Man, this ARF is nice. It went together with great presicion cut parts and the covering is beautiful. I built it over a few weekends and today was the maiden. I took off after checking everything. It only took a few clicks of aileron and it was pretty much trimmed out. About 3 minutes into the flight I was still not really doing anything but circling the field and WHOA big time flutter. LOUD. I immediately tried to line up to find the runway...it was still controllable... landed with a small hop..not bad at all. Went out to get it and the right wing was obviously having issues. The covering was wrinkly and warped on the top side and the underside was screwed up and some broken balsa was exposed. Amazingly, The broken area around the servo seems to have preserved the integrity of the servo gears. The other wing was undamaged, but the servo gears are stripped and the servo endlessly searches for somewhere to stop. I was not flying aggressively nor fast. The servos are Futaba S3004, just standard ball bearing servos. I also flew my TT Spirit 3D today and its got full span ailerons unlike the Wildstick which was using only 1/2 the span of the wing's ailerons (flaps weren't activated). To me it seems like, well, I'm probably screwed. I think the right thing for Carl Goldberg Products would be to ship me a wing set. We'll see.

Wow; I have one of these in the box in my garage right now...

i got a hot stix 40 w/ about 50 flights on it .. havent had any problems. but i do the throttle managment thing. hardly ever fly it wide open, were you ?? just wondering

I test flew my friends, cranked around hard with it for a couple of minutes no problems. May be you just got a bad wing, did you have any slop in you linkages? This has a thin wing for such big surfaces, you can probably overspeed into flutter.

I was not doing anything but circles. Maybe a roll thrown in, but definitely nothing fast or 3D. Probably at 1/2 throttle when it happened. Linkages were tight. I used the supplied hardware. I'm going to call CG and see what they say.
