Whenever there is no steering input form the transmitter, my steering twitches back and forth very rapidly. It doesn't always do it, maybe 50% of the time, and it doesn't go the full travel of the servo, a few centimeters in each direction. Looks like it is twitching? I can't tell if it is doing it while moving, I don't think is does, cause once trimmed in, it will do a straight line.
Anybody have a guess as to what would cause that?
Also, if I put it on it's roof, and take it up to full throttle, it starts to vibrate violently. Is that normal?
One last thing, no matter how fast, or slow it's moving, when it is going backwards, the throttle input acts like a brake, until it stops, then I pull the throttle again, and it takes off? Is that some kind of a fail safe? Why can't I go from moving backwards, to moving forward without first coming to a complete stop?
Any help is greatly appreciated.
