FWIW, it happened to me. ~30 flights on the airframe. I was doing stairsteps when the horizontal stabs, elevators, vertical stab, and rudder all departed, along with the entire block that the horizontal stab bolts to.

I'm guessing that the stab hold-down block wasn't properly glued in. There's no glue residue anywhere on what's left -- I wasn't able to find the departed tail surfaces. I believe the vertical stab went when the horizontal stab ejected through it.

In the plane's defense, I tailslid it into a hard belly flop about 5 flights ago after the engine died in a hover at about 8' up. Maybe something gave in the tail then... But I think the hold-down block wasn't glued in properly.

So much for an inexpensive plane. 30 flights and ~$280 in flight damage. $190 airframe, 1 DS368 departed with the stab, and there was some engine damage.

I don't plan to contact GP on this since I did smack it in and it might be my fault. But I'm also not planning to buy another.
