Traxxas TRX-3 / TCP / Blue Eagle LSII / SRT Hinge Mounts (Various Toe Amounts)

thingiverse

Rear hinge blocks are designed to fit various vintage Traxxas vehicles, including TRX-1, TRX-3, TCP, Blue Eagle, Blue Eagle LS, Blue Eagle LSII, Hawk 2, Rad 2, and SRT models. These blocks will not work on Rustler/Stampede vehicles that have integrated mounts into the gearbox. The standard hinge mounts require a triangular wedge to be placed between the block and chassis to create Anti-Squat, but this creates an odd bolted joint that often loosens. The new rear hinge blocks create the necessary Anti-Squat directly in the hinge hole. I can adjust the anti-squat amount for each model based on specifications. To install these blocks, bore the hinge pin hole with a suitable drill bit (~1/8" bit) and tap the mounts with an M4 tap. UPDATE 07/29/20: An error was discovered in the original design, affecting the dimensions. This made it highly unlikely for most cases to fit properly, as the chassis would interfere with the hinge pivot. Although I was able to get mine to work on my Blue Eagle LS II, this may have been due to an earlier revision. The design has been updated to match the latest Traxxas geometry (both 1 degree and 0 degree blocks). For the 1 degree version, some light filing near the front edge of the block should clear the chassis if necessary. New variants include 1, 2, 2.5, 3, and 4 degree anti-squat options for both 0 degree and 1 degree blocks. I may create a version that reduces toe-in by 1 or 2 degrees in the future.
