FLM Chassis - Roll Bar???

i use the plastic rollbar from the x, not the part that used to cover the engine, just the plastic "handle" but it doesn't do anything towards protecting the electronics since it mounts all the way up at the transmission...i smashed all my electronics from not having something back there, the towers compress too easily...im thinking of making something out of extra engine plate braces for the esc and battery...but i don't want it to stick out of the body (pickup truck body)
