Default Problem with Gnat

Need some advise. On the maiden flight my gnat wants to tuck under or loop with power on. With motor off it seems ok. Has anybody had this problem before. The CG is about 3.75.

We are flying a bunch of Gnats in my area, most with the CG at 3 3/4 inch. They are flying pretty well. Do you have the ailerons pulled up so that the bottoms are AT LEAST even with the alum. channel bottom? If you want take a look at the article at [link=http://www.wildwingscombat.com]Wild Wings Combat[/link] for info on what we are doing. The Gnat is great for club combat as a starter plane for combat. Most here are using the OS 15LA with the 8 X 3 combat prop spinning at 17,500 rmp. Hey Good Luck! DickB

raise your ailerons a bit above the bottom of the fuse.

The ailerons are even with the bottom of the fuse. I will raise them a little and try it again. Thanks DickB and bhole74.

Thanks Guys I moved the CG forward a bit and adjusted the ailerons like you said and it flys GREAT.

Thanks again
