Thanks guys yes it's the foamie Extra 300 and main problem is the more flat on top and more rounded on the bottom airfoil. It's very twitchie even after 40% expo and if over or at 50% throttle it pitches wildly up and down. I have flipped the wings upside down to try but may see if I can trade it with someone for a T-28 Trojan before I crash it. I've flown it 3 times and don't find getting any better. I'm not the wildest flyer around but have flown 10 years or so. Dont' know if I want to try it with the wings flipped or not. Not the 3-D type of flyer. More scale like for me. I won the plane at a fly-in! Would not have bought it.

Thanks,
Jim
