r is 4 reverse, and if none of rolex's tricks work, it might be your glow plug, i ghad this problem for a little while(i have the firestorm) i still havent gotten a new glowplug, but if you turn up the idle engine speed, using the adjusty thing on the controller b4 u start it, it should run, just make sure to keep the car moving, dont let it idle for to long, that will work, but i'd recomend checking your glow plug, thats probably your problemo
