Footage of my 2-Speed conversion kit for TRX4m. Uses a FCX24 trans. Mods for this rig:
Oppai Factory 2-Speed Conversion (High Clearance)
Mofo RC Torque Beast Brushed 180 motor
Crap 30a $10 ESC (just to get me goin)
Ebay full metal FCX24 2-speed w/ brass gears
Mues DIY Portals (25% gear reduction)
Injora Axles w/ 24/12t helical hears
DJ Crawler 68mm Tires
x2 Globact 5kg Servos w/ signal reverse for 4ws
Injora 12-Spoke beadlocks w/ full ring set.
Injora Tarantula chassis w/ pop can panels
Flysky GT3c Transmitter w/ GR3E 3ch Receiver
Super fun lil rig. Really makes you wonder why Traxxas didn't 2 speed them out the box. Almost as fast as my Prerunner build, which is on 3400kv brushless and Injora Speed Gears.
