This video includes some very interesting discussion about how a ground crew adds value, and why it is important to understand the background of the folks supporting you via the radio. On the early space programs they used non-flying pilots for this role, at Wasabi it's typically Justin and I trading off the test conductor / chase pilot role. Unfortunately Justin was in Hawaii supporting another Wasabi customer and he was sorely missed.
This video covers the entire Wasabi portion of the program from the inspection through the three successful flights to the final flight in the airplane. It's a long journey, feel free to use the timestamps to jump around.

The Wasabi relationship with the LongNose goes back to 2016 but this particular series is about the program to retrieve the airplane from Deland Florida where it was having some engine work done by Quentin Cook at Turbine Power Technologies. I hope you enjoy. Meet you in the comments.

A functional check flight is always a milestone in a program. This was particularly so because of my history with the airplane and the failed attempt the day before. The big questions surrounded the brakes/reverse thrust balance, and the new oil cooler arrangement.
When I arrived at the airport that morning Quentin had already started retouching the reverse thrust rigging and checking the oil leaks found the day before. Check out this extended sequence where we work to rig the reverse setup on the engine.
This engineer is doing his best to foreshadow an interesting episode 3. Let me know how I am doing.

This is the first day of the program which at Wasabi consists of aircraft inspection, engine runs, and low-speed taxi. We don't always get to talk about our inspection process but it's a critical part of the program and this airplane has some great examples of why it's so critical.
One of the first big lessons I learned as a professional flight tester was about the end of the program. When you own an airplane there is a connection to the future of the airplane which is long and therefore emotional. In flight test, the connection is to the data and the airplane is just a tool, a tool that will be taken away when the program ends. So you can't get attached.
The LongNoseThunder was one of those programs that despite my best efforts was hard to walk away from...so it felt good to see it again.
You can see the exact moment here: youtu.be/GXJ4dRiR4Cc?list=PLWF16HYaxBicK7vlp6Ec4c13j_OvwXcQT
This Walter turboprop equipped carbon fiber Thunder Mustang and I met several years ago in Chino California. When we met the airplane was dusty and out of annual in the back of a Threshold Aviation shared hangar. The airplane had sat patiently while the owner advertised the airplane for sale. This drooling engineer dork was super excited about the opportunity to work on the airplane. After six months of work and ~20 hours of flying I delivered it to the new owner in Colorado and didn't hear much more.

Check out Håkan's "stall vane" a lower drag alternative to the VGs we saw on flights 7 & 8. You may recognize the idea from the SR22 Cirrus (they call it a fuselage vortex generator). On this flight, we evaluate the handling qualities of the "stall vane".

Flt 009 Flight Report
Summary
Flt Date 12/30/2020
Engine Start: 9:28 LCL
Engine Shutdown: 11:04 LCL
Flt Time: 1.6 HRS
Landings: 1
Fuel State Takeoff: Full Tanks
Total Time After Flight: 7.8 Hrs
Chase: None
Data:
Takeoff MAP 26.2" at 2780 RPM. The throttle/mix/prop levers did not move with the nose gear retraction.
Three stalls at 45° flaps w/ gear down, ~48 KIAS.
Three stalls at flaps 35° w/ gear down, ~50 KIAS.
Three stalls at flaps 45° w/ gear down, ~48 KIAS.
All stalls found to be comparable to the wing/body VG stalls. Perhaps slightly lighter elevator forces w/ the stall vane, but not a problem.
Rate of climb check flaps 45° w/ gear down - WOT @ 2750 RPM and 80 KIAS, 275 FPM.
Rate of climb check flaps 45° w/ gear up - WOT @ 2750 RPM and 80 KIAS, 325 FPM.
2 cloverleafs at 55 KIAS (53 and 56 KGS) at 6,000' and 5°C, 48 KCAS. (indicating high by 15%).
2 cruise cloverleafs at WOT (19.4") and 2500 RPM, ~140 KIAS or 134 KCAS (indicating high by 4%).
The landing was flown w/ 35° flaps and an approach speed of 85 KIAS. The resulting landing was fast with the nose wheel touching first and an associated bounce.
The inner gear door actuator started leaking after the stalls.
After flight, it was determined that the altimeter and MAP indicator were both indicating in error. The altimeter showing ~1,000 feet low, and the MAP showing 1" high as well.

Summary
Flt Date 12/5/2020
Engine Start: 2:30 LCL
Engine Shutdown: 3:45 LCL
Flt Time: 1.3 HRS
Landings: 1
Fuel State Takeoff: Full Tanks
Total Time After Flight: 6.2 Hrs
Chase: None
Data: All stalls required more active Lat-Dir maintenance by the pilot, the missing wingtip VGs had more effect than expected. Alternate static resulted in a minimum indicated airspeed of 0 KIAS.
Cruise power (2500 RPM/WOT) at 8K (Press Alt) resulted in 144 KTAS (or 135 KCAS). At this speed the airplane indicated 126 on ship static. The significant reduction in cruise speed appears to be tied to the engine not reaching full power, likely tied to the throttle/gear interaction seen on flights 7 and 8.
Landing flaps up with an approach at 95 KIAS was adequate.

Next Steps:
Need to redo performance testing once full power is confirmed. Then after confirming the cruise speed is adequate the program would be complete. In the event cruise speed isn’t adequate I would test stall handling at AFT CG limit, then remove VGs until control and stall speed were only just adequate or until design cruise speed is reached.

In this clip (excerpt from Flt 7 of Hakan's modified Lancair) we explain the value of the trailing cone and how it applied to this program. We also went through the details of getting the cone to the end of the runway and then airbornes at this busy and towered airport. Come along and let us know what you see that we don't.

----Flt 007 Flight Report----
Summary:
Flt Date 12/5/2020
Engine Start: 10:20 LCL
Engine Shutdown: 12:35 LCL
Flt Time: 1.3 HRS
Landings: 1
Fuel State Takeoff: Full Tanks
Total Time After Flight: 4.9 Hrs
Chase: None
Data: My initial impression is that the difference in drag between 35° and 45° flaps is the most significant change. The aircraft handles nicely during a full flap stall with plenty of roll control and little tendency to drop a wing. The elevator position/force difference for flt 7 vs flt 6 was significant, likely due to the VGs added to the wing and tail. It took more elevator deflection to stall, and there wasn't the significant force change during the stall that was observed on flt 6. Worth noting, the flaps up stall is now the limiting stall.
The trailing cone showed little difference vs the ship static (stock location) in all configurations tested. The biggest difference was in the last 5 knots of the stall, during which the ship static would show an airspeed increase (~5 knots) while the airplane was still slowing, and the trailing cone showed a steady reduction in airspeed.
The GPS clover leaf showed an error (12% clean, 15% 35° flap, 20% 45° flap) at 1.2 VS, with the indicated speed being higher than the GPS calibration speed. Based on Hakan's CFD, he believes this can mostly be traced to pitot error due to high AOA.
On landing at 110 KIAS (as all previous landings) the difference in actual speed was apparent. Estimate the airplane was 15 knots faster than previous landings (recommend future approaches at 95 KIAS)

As Ashlee mentions Justin and I's initial interview with them was just a couple of weeks after the quickie accident. You can see my black left eye in one of the interview shots. The quickie wreckage is behind me in the hangar, I had it hidden because it was technically quarantined while we waited for the NTSB to review the engine controller data. The other incident mentioned is discussed in the most recent Lancair video (youtu.be/5jYgLp372Jo?t=255). It was a really interesting emergency on its own but it was certainly compounded by the recency of the quickie accident etc. The engine is related to race 33, which blew up a couple weeks later (youtu.be/mvu_9dATSG0).
Jennifer Whaley Seguin was pregnant with our first at the time and needless to say life was full. They say when it rains it pours, and all you can do is put your head down and keep swimming. I wouldn't trade that time in my life for anything, but looking back on it now...things were busy.

Some of the most frustrating experiences in flight test came after the airplane was broken and the owner felt like he hadn't agreed to the risks that had been taken. If I blew it in the cockpit that's one thing. But not communicating what we were getting ready to do and why when the airspeed and altitude is zero is a whole other level of blowing it.
Since then I have tried to do a better job with these tough conversations, then record them, and then record flight. These permanent records do wonders for limiting the space for the argument over the broken airplane parts.
If there was any one thing I wish could be taught about flight test it's here in this space. I have been trained to see and quantify risk, but the real art is in effectively communicating the risk to the stakeholders at the appropriate time.

The flight was a major envelope expansion for the program. The huge custom flaps had taken 4 years to get to this point and the results were mixed. The flaps had moved, they hadn't jammed or come off the airplane, the pitch trim had changed (an indicator that the flaps were making life) but the stall speed hadn't changed. There are a range of suspects from a larger area of separation at the wing root than expected, to the pilot's perception that the elevator had stalled, to the simple question of a new static port adding error to the indication. It's impressive that now several weeks later, after looking at all the data we don't know much now that we didn't know when this conversation happened.
Some of the most interesting experiences I have had in flight test have happened at this intersection between engineering and flying. And it's unusual to have such a great record of it that we can also share. I feel very fortunate to be a part of this program.

Summary
Flt Date 10/23/2020
Engine Start: 2:34 LCL
Engine Shutdown: 3:28 LCL
Flt Time: 0.9 HRS
Landings: 1
Fuel State Takeoff: Full Tanks
Total Time After Flight: 3.6 Hrs
Chase: None
Data:
First attempt to fly was stopped by a jammed propeller governor lever. We decided the problem was a drop of gasket seal that fell on the shaft of the lever. During the inspection the seatback was removed to make more clearance for the parachute. This was a much better cockpit configuration.
For the actual flight the engine started well and sounded healthy, we believe this was the induction work that Hakan performed. The engined reved to the new governor setting of 2800 on takeoff and the acceleration difference was noted on the ground and in the cockpit.
The data portion of the flight was flown between 9-10,000' MSL. The pattern was: at 90 KIAS change flap position, note trim change, accelerate to VFE (100 KIAS) handling check, trim change check. Slow deceleration to a handling/trim check just above stall speed. Alternate static check found no change in altimeter reading with valve actuation.
The flaps were checked at 10°, 0°, 10°, 15°, 20°, 25°, 25°, 30°, 35°. There was a small pitch trim change with the extension of the flaps, the trim was at the up stop, but the stick position change was very small. Wind up in the flap deployment mechanism was noticeable and it would take some time for the flaps to settle after being deployed.
The stall speed did not appreciably change in the range of flap configurations checked. While the bleed rate was not 100% repeatable between stalls this was not expected. It appears that the stall is driven by a loss of control power (large separation on elevator) rather than a stall of the wing, but there is a large separation forming on the wing at this same time. The flap does not appear to separate during any of the stalls. We knocked off at 35° to check the tail video for risk of tail stall.

---End of report---
Flight 5 happened the same day as flight 4. Since we had finally been able to get the engine to cool well enough to fly the entire first flight card (on flt 4) it was time to get a baseline (on flt 5) before we started flap testing. These huge Fowler type flaps are the result of tremendous engineering and fabrication effort on Hakan's part and it's super exciting to be wrapping up the last bits before that fun testing.

Total Time After Flight: 2.7 Hrs
Chase: None
Data:
Engine start was normal. During climbout engine would not rev above 2600 RPM. Climbed to ten thousand for the dive test. Stick wraps found the pitch axis the least damped (still very damped). Both roll and directional axis were dead pan. After the dive test we descended to 8,000' for a speed power. At 170 KIAS (WOT, 2500 RPM, 1250°F) it wasn't clear that the airplane was done accelerating so I knowcked it off. Then we climbed to ten thousand for the stall checks. Three stalls were performed (power off, gear and flaps up). The first two were at roughly 70 KIAS and resulted in a right wing drop and no other noticable characteristics, stick still had 20% aft stick remaining, stick force was still positive. On the third stall I led the stall with left rudder and was able to get a pitch bobble and a left wing drop, not to mention the stall speed was closer to 65 KIAS. After the stalls we dove the airplane to 180 with stick wraps to clear the speed envelope for another cruise check. Cruise check speed power at 8,000' MSL, WOT/2500/1350°F, 170 KIAS (215 MTAS). In cruise #1/290°F #2/364°F #3/359°F #4/352°F OT/180°F. During the descent the gear speed envelope was opened to VLE (122 KIAS). Landing was nominal.

Besides the obvious the first flight card included a "first look" at the low speed handling chracteristics of the airplane. The concern is that while the flaps may allow the wing to make enough lift to support the airplane at very low speeds the controls may not be powerful enough to control the airplane in this condition. Most obviously this is a pitch problem as the giant flaps are sure to make for large pitch moments. But also the airplane will need to turn (roll/ailerons) and yaw (rudder) at these slow speeds or worse during a go around.
Hakan is an experienced homebuilder so knocking out this small lip on the cowling exit was not a major challengefor him. We added to it by taking advantage of a low "marine layer" day and flying early when the air was still cool.
Yes this mod adds drag to the airplane. But right now highspeed performance is not the main concern.

One of the more frustrating things in flight test is when there is a problem that can’t be tested except in flight and the over and over again you aren't able to make progress. Trying to be professional and deliberate when despite all the pageantry the flight doesn’t seem to progress takes discipline. This flight was the third time that we tried to fly this card and even during briefing you could feel the fatigue.

Chase: Gillen/N131RG
Data:
The flight was delayed with a very busy traffic pattern. This was the first time we were asked by the tower not to make status calls on tower frequency, which dramatically reduced the value of having chase. By the time we were cleared for takeoff the engine was hot (CHT 380°F, Oil 180). Takeoff was flown at WOT, full RPM 2640, full-rich mixture with the fuel pump on. Before reaching crosswind CHT was out of limits but the tower was very busy and traffic was lined up to get into the airport so I stayed at climb speed (125 KIAS) and power (WOT/2500) until downwind abeam. Peak CHTs by cylinder 1/408°F 2/451°F 3/398°F 4/428°F. Power was reduced and the approach was flown at the corrected approach speed 110 KIAS.

Landings: 1
Fuel State Takeoff: Topped
Total Time After Flight: 0.8 Hrs
Chase: Gillen/N131RG
Data:
Takeoff was flown initially with full mixture but was leaned (~2") shortly after brake release. This was done by feel due to rough running and a "high fuel flow" alarm. Before the crosswind turn CHT showed 400°F at which point prop was reduced to 2500 RPM, mixture was set to full, and the aircraft was accelerated to 130 KIAS. The flight was aborted due to high CHTs (417°F peak)during the downwind leg. Peak temperature was reached at 130 KIAS WOT/2500 with full mixture and the boost pump on. The EFIS was not set up to show which was the hottest cylinder during the flight. The aircraft would not climb very well in this configuration/speed (peak altitude 1100' AGL). Oil stayed remarkably cool 100°F peak for the flight. Nose gear doors much tighter than the previous flight.

Thank you for reading all the way down here. I (Elliot) feel very fortunate to be able to do this work and more so to be able to share it with you. It means a lot to me that you come along. So again thank you let me know how I can return the favor.
This video is a very long archive of our work with Raptor up to July of 2020. This includes our decision to pass on the Cherokee airport as a location for the first flight. This has been a difficult trip/program and a hard video edit, please let us know in the comments what is unclear.
We typically film to keep a record of our test programs. However we don't get to talk about most of the work we do. On previous trips to see Peter we kept details light per Peter's request, he runs a well-manicured vlog on the program @Raptor Aircraft and needs to control the story. This was the first time that Peter asked us to publish a detailed video of our work and we are excited to do so. I hope you find it useful.
Warning!! This is a long video, below is an outline with timestamps if you want to jump to a specific part of the flight.
My apologies for the popping in the microphone, it's new and I should have tested it more before we left.
Thank you for coming along with Wasabi Flight Test. We hope that there are lessons learned in this video that can be applied to your aircraft projects. We would love to help you with your flight test project, give us a call. Thank you!

Flt 015 Flight Summary
Engine Start: 12:03
Engine Shutdown: 12:44
Flt Time: 0.7 HRS
Landings: 1
Fuel Used: UNK (totalizer failed)
Total Time After Flight: 14.2 Hrs
Start CG: 89.20
Data
Planned to be a short leak check flight (with neon oil tracer in engine oil). The hydraulic anomaly on initial gear retraction cut the flight even shorter than planned. On landing the oil leak of concern was found, traced to an oil pan leak.
Power Settings
Take Off 42" 4200
Climb 30" 3500
Cruise 25" 3000
Speeds
VL - 130 MIAS
VF - 150 MIAS
VAPP - 100 MIAS
Maintenance Before Flight
- Play in the stick was addressed, bolts found loose (1-1.5 turns) in roll and pitch axis at the base of the stick.
- The hydraulic system was checked and adjusted.
- P1 actuators were rebuilt due to failure (overpressure) on the previous flight.
- Hyd system pressure was adjusted down from 1300PSI to 1050PSI
- The gear was cycled on the ground to check for leaks and functionality.
- Refilled the reservoir.
- Engine oil leak was addressed, traced to a 90° elbow fitting that drains the dry sump oil pan. The fitting was replaced and the engine was extensively ground run to check for leaks.
- Analog tachometer (intermittent) wiring harness was checked but nothing was found, the problem is believed to be in the gauge.
- Fuel flow sender (not indicating) was sent to the manufacturer and passed their checks. The problem is believed to be in the engine management system and or wiring harness.
- PSRU pressure regulator was adjusted down to 100 PSI. This system feeds the propeller governor.
Squawks after the flight:
- 2 cylinders fell off (EGT) on the descent, backfiring. The mixture was full for the entire flight, this is likely the problem (hot summer day). The boost pump was off.
- Fuel flow not working
- Analog Tach Indicates 50% of the digital tach
- Pitch bellcrank behind rear seat center bearing loose.
- Gear would not retract initially at 130 MIAS, likely due to low pressure. system pressure 650 PSI for up and 1050 when gear selected down. With time and a low G bunt, the gear finally retracted (confirmed by airborne chase). Gear extended normally.
- Engine oil on belly after shutdown
- Hydraulic oil on the right gear after shutdown.
Next flight:
The first priority is to confirm the gear is functioning again (pressure is high enough to actuate with air loads, but not so high seals are failing). Once the engine is confirmed stable again we need to work on extending the CG range.
Thank you for tuning in, we appreciate the support and feedback. Airplanes are cool

Flt Time: 0.5 HRS
Landings: 1
Fuel Used: UNK
Total Time After Flight: 0.5 Hrs
Chase: Gillen/N131RG
Data:
The flight was cut short due to engine cooling. The radio sounded good. During the high-speed taxi the engine was determined to be rich (based on sound, engine smoothness, and indicated FF). The engine was leaned (~2”), found to run smoother there. That mixture setting was used for takeoff. Normal takeoff, normal gear retraction. Nose gear door was found to be open ~1”. One minute after brake release the CHTs were out of limits and increasing. To cool CHTs, the mixture was set to full rich, we accelerated to 130 KIAS, and the power was reduced to 10”/2500 RPM. This reversed the trend on the CHTs. While we waited for CHTs to get back in limits to continue the test card, the oil temp went out of limits and increasing. At this point, the decision was made to RTB. A normal landing was flown flaps up. During the approach the airspeed was checked with chase and found to be 10% off, the Lancair was indicating 110 KIAS but chase showed 100 KIAS.

This video introduction to Jason Hodge's new Tora Tora Tora “Zero” T-6 was the supposed to be a simple functional check flight. But a gear anomaly on that flight stretched the program out. So this video contains all three flights we did in the airplane after the propeller overhaul at Sanders Aeronautics before repositioning the airplane to it’s new home at Nut Tree Airport. Jason plans to take the airplane on the airshow circuit but otherwise it will be on display in the Pacific theater area in the Warbird Aero Services hangar.
The gear issue we experienced on the functional check flight is still a bit of a mystery. We examined the linkages for the up and down locks, serviced the hydraulic system, and inspected for broken parts. And we cycled the gear several times on the jacks in the hangar. So, for now, we will just keep an eye on it.
For the handling qualities portion of the program, I focused on the longer wingtips. As you can see in flight one the stall speed was lowered by the tips, so the question was what other effects did it have. We looked at the dihedral effect, dutch roll damping, and roll rate. There was some discussion about whether the three-blade propeller would be destabilizing we could effect dihedral effect and dutch roll damping. We didn't have great baseline data (we may have some soon), but it seemed unlikely the tips had a major effect on any of these handling qualities. So if you back up and look at the entire zero mod package the most noticeable difference is likely stall speed, or perhaps more acceleration on takeoff.
The firewall forward on the airplane is off of a DeHavilland Otter. Its a geared 1340. Despite being geared the manifold pressure and rpm settings are the same...which is likely why it's rated for the same power as a stock R-1340 on a T-6.
I didn’t grow up with Tora Tora Tora the movie, but I certainly saw the airshow. Meanwhile “Empire of the Sun” was absolutely a big part of my childhood. That being said I never appreciated the effort that went into these replicas. They actually flew modified T-6s off the deck of the USS Yorktown (simulating the Akagi aircraft carrier) in pre-dawn light during the making of Tora Tora Tora. Really impressive!
There were 19 T-6s modified to look like Zeros for the movie at a cost of roughly $12,000 USD each (~75K in 2020). The modification work was done at shops in both the US and Japan. A total of 52 aircraft were modified for the movie including a B-25 which was modified with a single tail to resemble an A-20 (it was crashed for the movie).
For 5 months in early 1969, a small airforce averaging 27 planes burned 3,000 gallons of gas a day. Twelve full-time mechanics were required to keep the aircraft flying and every aircraft eventually needed an engine overhaul. The pilot cadre was made up of active and retired military pilots as well as civilians. They treated the flying job like a military assignment with early morning briefings and flights as they gathered footage and developed procedures for the movie.
If you get a chance look into the footage of the P-40 crashing on take-off. The RC controlled full-size P-40 was rigged to explode but lost control and went through the row of static P-40s also rigged to explode. The stuntmen running from the explosion is impressive because it’s real. Check it out, it will stick to your ribs.

Flight thirteen was cut short when a feed line for the propeller governor came loose emptying the PSRU of oil and compromising propeller control. this video is an experiment for us, with more technical depth than we've ever shared, making it the longest video we've done on the #Bowerspony. A big thank you to Rod and Eric for letting us be a part of the program and share these lessons learned. Also a big thank you to Justin Gillen, the other half of the Wasabi team and our chase pilot for this flight.
The flight was planned to be a shakedown flight after a six-month maintenance stand down. On flight 12 the PSRU (Propeller Speed Reduction Unit) had started leaking and after a lot of effort Rod and Eric believe they have it surrounded. We look forward to flight 14 where we can continue to develop this new firewall forward for the Stewart Mustang.
Thank you for coming along with Wasabi on this day of testing. We hope that there are lessons learned on this flight that can be applied to your aircraft projects. Let us know what you think of the new format. Thank you!

This the last flight of the JellyBeanThorp program included a dive to VNE (never exceed speed or redline), a wind-up turn to the published maximum G for this weight, and finally a minimum entry speed exploration for loops and rolls.
Likely the highest risk flight of the program it was also tons of fun. Super stoked to have been able to fly this famous Thorp, let alone take it to the corners. It's always a bit bittersweet when a program wraps up and you have to give the airplane back to the owner...and I can admit this one hurt more than most.

The Raptor is a new aircraft designed to revolutionize the GA market. Canard, five seats, carbon fiber, powered by a diesel automotive conversion engine. The airplane features a wide cabin, glass cockpit, and a BRS.
Marc Zeitlin of Burnside Aerospace was brought in to help with the inspection. We met Marc when we all worked at Burt Rutan’s Scaled Composites together. Now he works for himself doing engineering and A&P work, he specializes in canards. We brought Marc out as a subject matter expert on this class of airplanes.

This was after the series of pitot-static calibration flights and included the newly installed fuselage-mounted static port. Previous flights are linked below.
The build-up was flown over 4 flights that morning. Because the airplane had previously been through a phase one test program we could move much faster than normal. But we were able to get clean and dirty stalls at each CG. And with the cameras (and google earth) we could back out take-off and landing performance.

This was the first flight of the new pitot probe. The goal was to compare the cruise and stall points we had gotten on the previous flight were not dramatically changed with the new pitot probe.
The biggest difference between the two probes was the initial probe was a larger Prandtl style pitot/static probe (static source on the probe). We were at this point pretty confident we would be drilling holes in the fuselage for a conventional tail cone style static probe. But drilling holes is scary, so we wanted to do anything we could to confirm this was the right path.
The crosswind ended up dying down during the data portion of the flight so the effect ended up being small. But this was an interesting chance to learn about all the side effects of a trailing cone, especially in a small test team without safety chase.

A trailing cone is a device used for pitot static calibration. The device consists of a drag cone that trails behind the airplane suspending a static probe. By positioning the static cone well behind the airplane the static measurement is less affected by the presence of the airplane itself.
I was trained on trailing cones at the NTPS (www.https://www.ntps.edu/).
The FAA provides some limited guidance in AC 23-8C "Flight Test Guide For Certification Of PArt 23 Airplanes", in appendix 9.
There are some drawings of trailing cones with dimensions that were released by Bede (27 & 28). bd5.com/BedeDesign27.jpg

I was looking at the logbook and realized I hadn’t done an airborne pickup or drop off in too long. So I bribed mandude with beer 🍺 and flowers 💐 to act as a target for #wasabinought safety chase practice. Retracts, a big motor, and a controllable propeller make energy control easy in the SX...and it’s always good to fly with Sparkle.
Part of Dennis' painstaking rebuild of the airplane included many updates to the airplane. Lou Sunderland (builder of this airplane) was a tremendous homebuilder/experimenter, and what a tribute to him that Dennis fell in love with the airplane and decided to bring it to the "Sanders" standard. This included complete rewiring, an overhaul of the flight control system, and most notable to this conversation a new panel. That new panel included a new (more conventional) wing-mounted pitot/static probe and a new engraved panel. The trouble was this engraved panel included the published speeds for the airplane (including stall speed) which drew attention to the error.
A pitot/static (or Prandtl) style probe combines the total pressure and static pressure ports in the same probe. This makes for a super clean install and a great looking probe, however, it is not typical on the T-18. This stock Thorp had the pitot and static probes in the top of the vertical, and this airplane was set up that way when Dennis got it. I assumed the path forward was to a more conventional tailcone mounted static port. So before I asked Dennis if I could drill a hole in the side of his gorgeous airplane I decided we should be super confident in the path forward. So I decided to do some homework, get out my old NTPS notes and get this problem surrounded.
Super stoked!!

This briefing is for the high-speed taxi and first flight of Alex Russell's gorgeous RV-7. It was a big group that morning, so I tried to give an informal brief that would help the group understand what we were planning to do. Big groups for first flights are hard but Alex had done a great job that morning of setting the tone and that really helped.

My first flight in Dennis Sanders’ freshly rebuilt T-18. The rebuild included engine upgrade to the 320 and a constant speed Hartzell. We had some questions about the pitot static system, the charging system, and the GPS/autopilot. A great excuse to learn a gorgeous airplane.
🚀⚡️⚡️⚡️
This week's #bowerspony flight 12 was all about leak checks and breaking in the new rings. The engine was rebuilt after some FOD damage in the spring. A quick flight to compliment the ground leak checks that @bowers51mech has been doing to confirm the new engine installation.
Jim had never been in Dreadnought, and had never gone this fast, his face when he landed said it all. With a little more work we will get him converted to this type of flying.
Meanwhile there are always airplanes to be moved between the hangars, and Owen (Dennis' grandson) has taken to riding along on the tug. Dennis built that seat on Tugnaught for Shannon when she was Owen's age, she also liked to ride on the tug. As excited as he is, Owen isn't big enough yet to run the tow bars, so Stephen takes that job.

The flight went well and the airplane flies as good as it looks. There were some issues with cylinder and oil temperatures (typical) but not so bad that we couldn't complete the test card. Thank you, Alex, for letting me be a part of this special day, congratulations on your tremendous new airplane. Artwork by @btmichael

This was the morning after our late night low-speed taxi. We had arrived at the airport with the intention of moving quickly through fast taxi and into first flight.
~~--~~---
The goals of the fast taxi were similar to that of low speed just at a higher speed. At full power, as the airplane accelerated, directional stability was checked. When the airplane reached 50 knots power was reduced to hold that speed and the elevator was checked. Forward stick raised the tail for the first time. Then roll power was checked, power was reduced and the brakes were checked. As with all fast taxi testing there is some risk of inadvertent lift off, we briefed that in that event we would go ahead with the first flight card.
~~~---~~~
While this “to the book” RV-7 is not the highest risk work that we do, we still use the same approach, with similar milestones and risk build-up. Fast taxi also has the added benefit of giving me one more chance to nail the sight picture for that first landing :) Airplanes are cool

This was the night before we flew the airplane. By the time I drove from Sanders Aeronautics to Lincoln it was too dark to do the high speed taxi test we had planned, so we were limited to low speed. By keeping the airplane below 50% of stall speed we could get work done without big risk exposure. The card had other items but running the engine, comms check, and attempting to get the tail up were major tasks that we were able to get done despite the low light. All of which would have otherwise had to be done the next morning before the flight.
~~~ ~~ ~ - -- ----
Practice session to get the rust off. The fire guys were busy so we had to clear the course in the middle of the session, but we still got 4 laps. Good to be back on the course, the airplane is running great. Thank you Dennis and the rest of the Sanders gang for a great opportunity.

An airborne check of the two newest Smokewinders in existence. We normally ground check the generators before we ship but since we recently flew a set of Belgian generators on Argonaut the airplane was ready to go. So we took advantage of this opportunity to triple check that the generators are working great before shipping them to the customer.
-------
These are the 21st and 22nd Smokewinders delivered this year. A record year for our young team of technicians and staff. To celebrate we invited Sanders team members Katy Lewty and Geoff Highsmith to come along on the test flight. Geoff manned the camera in the chase plane (#Wasabinought). Katy sat in the back of the Seafury (Argonaut) and ran the generators. You can see Joel Swager (pilot of the Seafury) tell Katy when to turn the generators on and off on this less technical portion of the test flight.

A great day at Sanders Aircraft.

We used a bed pillow folded in half to boost him up a bit, I wish we had doubled the boost. You can see I was keeping the airplane in a bank as much as possible so he could see what was going on.
Gid wore a Bose headset which fit much better than we expected, and he was able to use the intercom which made things nice.
We flew off to the west of Rosamond Skypark, past Willow Springs Raceway and out over the windmills toward Tehachapi.
A lovely flight.
Thank you to Dennis and Ruth Sanders for the opportunity.
