The neighbors don't have to worry about the squiters tonight. I can't wait until I get the chance to try it in the air. Might even get a fes pictures.

Status: offline 		Has anybody had any aileron problems? My right one broke off about 6-8 inches from the end.(While in flight) Boy what a great flyer. I never could tell it by the way it flew. I'd not even got nervous if the others would have just said to land and told me what had happened. Instead of screaming something came off. Boy that gets your bp righ on up there. I did not see it come off. I heard a strange noise, but one of our other pilots saw what happened. They walked out in the bean field and found it. I have made repairs and am fixing to rehinge the aileron. She'll be ready to fly again soon.

Just to clarify: Did the aileron come apart or did the hinges fail and it simply came off? The stock CA hinges included with the ST90 are a known, well-documented problem and should definitely not be used.

Status: offline 		P-Diddy,
Some of the guys at the field said that it looked like the hinge had failed.The one on the very end was broke in half along the hinge line. and the wood had seperated from the hinge on the next one in. Are you using robaart type hinges or CA hinges?

Zippi,
Mine was purchased used two months ago. I never saw the guy I bought it from fly it, but I feel like it is a newer version. Mine does not have that snap tendency that everyone talks about. Mine flies great at slow and fast speeds even with 2/3 of the aileron missing.
Thanks
Alan

Right before the aileron broke my buddy did some beautiful rolling circles with it. Could this have weakend the hinges? Also do you think I should replace all the hinges.

I've replaced all the hinges in my plane because, one by one, they all failed. Luckily, I was able to find 'em and fix it before a flight.

Status: offline 		I got some hinges problems too. I replaced all for Dubro nylon hinges. Much more precision and durability.

I believe the snap tendence of some Showtimes is caused by CG problems. Mine was flying some months ago with an OS 160 FX without any mods. She was nose heavy and had a huge snap tendence.

Now I made some mods ( http://www.rcuniverse.com/forum/m_7598780/anchors_7598780/mpage_1/key_/anchor/tm.htm#7598780 ) and she does not snap anymore. CG is like manuals says (I think a little bit more tail heavy). Is the same plane. I Didn't buy a new one.

After one of my elevators came off due to the hinges failing, I replaced them with Robart-style hinges. It doesn't take too much time, and they aren't that expensive, so I highly recommend replacing ALL of the stock hinges, especially if you, or someone else, are planning on doing any 3D maneuvers. The stock hinges are known for breaking apart at the hinge line and for separating, (plastic inner layer separates from fiber, porous outer layers).
