Welcome to this detailed Build Guide of the 2018 rereleased Tamiya Super Astute Rear Wheel Drive racing buggy. In this Part 2 we cover steps 12 to 17 of the build manual which uses all parts in Parts Bag B. The steps include the construction of the gearbox, building the differential and slipper clutch (or the TTC - Tamiya Traction Control system) and fitting the gearbox assembly to the chassis. Hopefully you will find a few tips and tricks thrown in along the way.
This Super Astute was a very generous donation to the channel from @RCJunky Thanks you so much, this wonderful kit is very much appreciated! 🙌👍
About the Super Astute:
* This is a 1/10 scale 2WD R/C model assembly kit.
* 2.5mm thickness FRP chassis gives a low centre of gravity for excellent balance.
* The battery pack position has been slightly enlarged. Please note it
is not compatible with square-shaped battery packs.
* 4-wheel double wishbone suspension employs CVA oil dampers.
* Sealed gearbox features TTC, which was Tamiya's first slipper clutch and protects gears from impacts and gives stable drive by limiting wheel spin. Externally the same as on the original, it features a modernized internal design, and can be adjusted simply by removing the gearbox cover and turning the lock nut.
* Efficient 0.5 module gear included. (25 tooth motor pinion)
* A low-profile servo is required for this model.
* High-traction front rib-spike and rear square spike tires provide superb response and awesome cornering.
* Comes with durable and lightweight polycarbonate body and rear wing, plus a protective under cowl.
