I put the maiden voyage on my sukhoi today. I have the CG set exactly as shown on the plans and the beast flew like it was way tail heavy. Every time I would get on the elevator it would try to snap. I have the high rate set at 1 3/4" 50 % expo and low rate at 3/4" 28% expo. I will move the battery pack forward and see if that will help tomorrow.

If anyone has a measurement on the CG from the leading edge on a plane that flys good please post it

Thanks
