Raideron, did the " glitch " happen near the same spot area over the ground each time ?
The reason I ask is the field where I fly has some violent updrafts and down drafts on calm days in one area. The first time I hit them I just knew I was having a mechanical malfunction or a radio hit, until I realized that no matter what the servos did my plane was not capable of maneuvers like the ones it was doing.
Just a thought.
