Hot Racing Traxxas TRX-4 Aluminum Motor Mount
Nice quality upgrade to eliminate the stock plastic motor mount. I added this along with the matching HR aluminum spur gear cover plate which holds this mount in place when I upgraded the stock motor and ESC to the Tekin ROC412 HD / RX4 setup as the HD series motors are longer and a bit heavier so I wanted to make sure the mount was solid and I wouldnt have gear mesh issues under loads. I also installed the aluminum HR transmission case along with a set of the MIP driveshafts and the Yeah Racing aluminum axle housings and all the Samix brass portal parts, and the entire drivetrain has been bulletproof for 2.5 years now, even with the truck weighing about 2 times what a stock one does. I did have one of the small portal gears break early on, but thats not bad for how much more power and weight Ive been running for so long now. Highly recommended for people doing brushless of higher power upgrades.
