A 33g 3-inch toothpick? Oh yeah! This thing is awesome! It has quickly become one of my favorites for ripping around my backyard and community parks. You gotta see this! Full parts list and tune below...

There is no bind-n-fly drone like this at the moment, but all the parts are listed below. If you want to skip the build, then I suggest this 2.5-inch drone: bit.ly/2OmkbHw. It's also pretty amazing and has a similar light weight feel.

Parts:
- BabyTooth Frame (1.5mm thick version): bit.ly/babytooth_3in_frame
- FPVCYCLE 1202.5 Motors: bit.ly/2U1YUHj
- BetaFPV F4 AIO w/ VTX (I used the older FC without VTX but I think it has been discontinued): bit.ly/360DJtO
- BeeBrain v2 Canopy: bit.ly/3a12kjb
- RunCam Nano 3 Camera: bit.ly/39w6QFK
- Gemfan 3018 2-blade props w/ 2mm shaft, as shown: bit.ly/2t3Ee6Y
- Gemfan 3016 3-blade props w/ 2mm shaft are another great option: bit.ly/2tM6NWN
- RENY screws on the canopy: bit.ly/3au3KD5
- Custom Rx and VTX antennas made by cutting these cables: amzn.to/2UoTOFg
- M2x3 motor screws (titanium if you can find them).
- Cloth tape for motor wires: amzn.to/2GUm5PD
- 2mm zip ties for antennas (Cheap option: amzn.to/3bSgBAu, better option: bit.ly/2DVSsfF)
- No prop screws (they are already tight enough with the 2mm shaft)
- 20AWG power lead

Batteries:
- GNB 450mAh HV 80C 1S: amzn.to/2Rh9ojz
- GNB 520mAh HV 80C 1S: amzn.to/2QV5AF6
- BT2.0 connectors: bit.ly/33XOhHW
- Check out this video to see how I replace the battery connectors: youtu.be/nmwOxncToJM

Tune:
- JESC 48kHz v2.3 (this free ESC firmware makes the drone much smoother and more efficient)
- Betaflight 4.1.1 with RPM filtering turned OFF
- Thanks to FaebuFPV for sharing this tune: bit.ly/2Jkzrme
