There have been some rumors that the composite-arf arplanes have been experiencing some wing failures. There have been 4 such rumors in my flying area alone, and if the rumors are true then there must be others. This is a concern for me because I have recently purchased one of these aircrafts.
If you know of a case where the Comp-Arf airplane has had a wing failure please respond. If there is enough response we may be able to find a solution to the problem or at least become more informed.
Thanks for any information regarding this issue.

Mr G,
Do you know if the wings that failed had the aileron servo bays 'boxed' as they should be?
I would guess that without the boxing there could be a little, yet enough, flex to induce a bit of aileron flutter which could almost instantly destroy the wing?
Let us know if you find out some more info.
rgds,
Mark

Mr, G,
Those claims are un founded me thinks. Some dude had a problem with the 52% composite (I forget the make, but it was not Comp-ARF or Fiberclassics) with wing failure, but it was concluded that he had aileron flutter wich lead to the break up. Don't Fret it - just fly the heck out of it![Wink](https://www.rcuniverse.com/forum/images/smilies/wink.gif)

The failure of the 33%ers are nonexistent as far as I am aware of, now the 3m wing has failed once that I know is fact, on the 20th or so flight pulling level from a down line the wing folded. The end result was my friend got a replacement withen 2 weeks. But this IS a extremely rare thing that a wing folds on any plane, and with the carbon blade spar I cannot see how you can fold it, maybe this is one reason they engineered a blade spar in the Super-Xtra? Fly it like you aint gotta dime in it! Stop worring your self!

I know of a 2.6m extra that 'exploded' in flight last year when the aileron
horns came out due to poor instalation (epoxy was still soft).
I wasn't there but I asked a bunch of the people that were at the event
and all said the same thing. It wasn't caused because of some defect on the plane.
At the time I think I was either waiting for mine to arrive or was just getting ready
to start instalation so I was concerned.

OK Guys, I've had a wing failure. Composite-ARF 2.6m Extra. Coming in to land I hit a pole and the friggin' right wing couldn't take the hit. Bummer
Good news is that the fuse was not much damaged and the left wing was 100% OK. I had to spring for a new right wing (outstanding issue as of now, I'll report on that after it's resolved). Must say I was impressed overall at the way the airframe withstood the crash.

One of my buddies had his wing seperate at the tip. It came apart right at the seam.
He noticed it after a days flying when he was putting it back in the bags..
He is sure he flew it at least once that way..
This was a 2.6M FiberClassics.
He re-glued it and has been flying it ever since.

Barry Finks brother had a wing blow apart last year at a competition. Don't remember what happened but it was a defect as far as I remember.

That's what Mike Brown told me when I asked what happened. It was during Mike's contest last year.

Hopefully these were all "older" planes that had the failures, and they've got the bugs worked out now in the assembly process. We'll still probably see or hear of failures (nothing is perfect), but I hope they are few and far between.
