my only RC is a radio shack x-mod, that i've done custom body works on, and a few upgrades include non-retail turn radius mod (50% tighter turns, which does wonders...you'd know what i mean if you've ever driven a stock x-mod, even with aftermarket tie rods) have stage 2 motor(will be swapping magnets, i currently run 6-cell AAA 1500mah each, i have two identical cell phone lithium polymer batteries, but i need a new main board, so it sits on the shelf lately..
