i get a "glitching" of my Spektrum + TC Spec combo sometimes..
its not often enough to be annoying or worry about though, but it does happen
occasionally when i power on my car the throttle control is very stuttery
turning it off and on, allowing for the rebind of the rx/tx, then trying again etc makes it go away
only once ever has my car cogged forward a bit and then stopped as if there was a frequency clash, but never again has it done that
