KaP- I never had a ground loop issue- i only said that I bought the GP ARF Skybolt from a fellow who ground looped it, and damaged the front end. So far I have had no issues with both of mine, both handle well on the ground, fly superbly, and land with only a click or 2 of power. I did put a little tow in on the orig L/G, on both, and they are very smooth and straight on takeoffs and landings. On my OS 61SF's I'm using a 12/8 APC on the yellow one, and since the GP is a lot lighter, I put a 12/10 APC on it, and it hovers nicely. I'm not a 3D pilot, but I had one of our best 3D pilots in the club wring out the GP, after repairs. and he really put it thru the paces. He really did enjoy flying it, even though it's a lot smaller than most of the stuff he flies. Keep us posted on ur progress-- Dean
