Injora Fat Viper Brushless Motors for the Traxxas TRX-4M
Injora’s going all-in on brushless power upgrades for 1/14 and 1/18-scale crawlers. Hot on the heels of their Purple Viper Brushless Motor release, they’ve unveiled the Fat Viper, a outrunner-style brushless motor for the Traxxas TRX-4M. With a larger diameter and a shorter length than the Purple Viper and other 180-sized brushed motors, the Fat Viper offers improved torque and overall speed thanks to two available KV ratings.
Available. in either 2000kv or 2400kv, Injora states the Fat Viper runs quieter than the stock motor and offers smoother overall performance. The motor package includes an 11T metal pinion gear and installation screw.
This motor is designed to work specifically with Injora’s 370-size motor transmission and isn’t compatible with the stock TRX-4M transmission. It requires Injora’s MBL32 Brushless ESC to function as well.
