I gotta agree with the flutter thing. I lost my plane two days ago when the left elevator fluttered. It bent the pushrod giving the left elevator a ton of 'down'. Was able to get into final but couldn't hold enough 'up' to keep it from nosing in.
The real bite is that the left elevator pushrod (wire) was the only kit supplied hardware that I had used. After the crash I found I could bend the wire with two fingers. Both elevator servos were in the tail with short music wire pushrods. The CA hinges did not pull out.
