i have a pegasus 40. the plane flies great. BUT, i have an os 46fx up front and it came out VERY nose heavy. i changed to a macs muffler and moved my battery to just under the vertical tail, and still had to add 3 ounces of lead to balance. i also just realized that on hard up elevator the plane snaps to the right. i calle prince america about this and they have no idea why the plane is doing that. i'm going to check the wing for washout or washin, and we'll see if thats the problem. hope you guys are having better luck.
