Yesterday, I put in 2 flights on the Huey and had a very close call. On the 2nd flight of the day, the tail started acting up. I got into a hover about 1-2 inches off the runway before it went into an uncontrollable yaw. I hit throttle cut, and there was no damage at all. On further inspection, the tail servo (MKS DS8910A+) was very jerky, and would randomly stick at certain spots. Guess its time for a replacement. I'm going to steal the one from the Apache so that I can have it ready for Helis Over Apache Pass this weekend.
