same thing happened to me aswell. I came out of a loop and a loud drumming sound straight infront of me. I pulled up, and nothing. It glided down at idle and smashed up all the nose. I have fixed it and fibreglasses the nose. Looked at the crash site and the clevis came straight out of the horn on the elevator. The clevis was still intact too, fuel tubbing and all. WEIRD!!! I replaced the clevis with the Dubro Safety Lock link and will be test flying this Sunday. But other than that one of the best flying planes I have ever had. Just the hardware that comes with the kit needs a bit of an upgrade.
