RE: Crazy servo question.
This may or maynot be the solution to your problem, but there was someone out at our feild who had a plane he flew perfectly the weekend before and then he brought it out the next saturday without chaning a thing and turned it on and realized his steering nose wheel was slightly cocked to one side. It took him about 45 minutes to an hour going over all his servo connections and receiver hook ups, but he finnally realized it was a switch on his transitter that he never assigns anything to. With this plane he some how has the steering servo mixed in with some other feature and it was controled with a switch on the transmitter. He flipped the switch and the nose wheel straigtened right out.
