Stomper and Ultra...My CG is good as the plans call for 4- 5/8" back from leading edge and it balances just slightly nose down and no lead. A guy at the field said to move the CG forward for less sensitivity. Would four inches back from LE be a good start? Gonna have to balance it again anyway, with the extra epoxy and ply I added. The plane does not look bad with all the work on the inside of the fuse. When I originally put on the fin and stab I loaded it with epoxy and it feels quite sturdy. I heard of others losing the tail, so I was sure to have it strong. Thanks for your help. Hope to have good reports from here on.
