I had the same thing happen to me on my second flight last week. Had a .46 FX with a 12X4 prop. In straight and level flight at half throttle the stab broke about 2.5 in. out from the fuse, on both sides at the same time. Plane went straight into the ground. NO FLUTTER INVOLVED. My plane had Dubro swivel links and Sullivan Quick links with Sullivan metal horns ( ABSOLUTLY NO PLAY ). All of my controls surfaces were gap sealed as well. Great Planes told me to send it back no questions asked. Am waiting to see if they will replace it? I have friends that have this same plane and they abuse their planes and nothing like this has happend to either one of theirs. Theirs fly so well thats why I bought mine.

Waiting to see how Great Planes Handles it. This was my first GP ARF, we will see if its my last!
