I've the DX2 and with my nitro crt.5 when i'am near of my truck (when i just start it and the truck is on the starter box) the trottle and stearing servo is crazy, goes from full trottle to full brake and steering goes left/right, like if the demon was psses the truck.
But when i'am with my electrique, nothing hapened, all is OK.
One thing that i'am sure, is that this winter i save some money to buy the new Futaba FAST.
