Hello,
I will put my "Two Cents " in on this plane..... My friend Chris Maier (by the way, Fifth in the Futaba Extreme Flight Championships ) and myself went to Buck R/C club so that Chris could "put the plane through the wringer" for the Fly RC review, and he snapped the plane just fine. Pequeajim did a fantastic job building this plane, and Chris did a fantastic job flying it. It is a very nice plane, and if it is set up properly, it is a very stable plane, and will compete in IMAC just fine...
Check your wing incedence, and see if it comes out at -1.5 ( on top ) as Jim said, and that may be why your plane doesnt snap as well as you would like.....
Hope that helps......
Blair
