Rigga,
I ran a calculation, the paint removal is not enough, moves it .5% forward. I'll need another 2% which will have to be done with weights. I've heard that Brantly blades are weighted at 70% span to accomplish proper CWCG. Hoping that someone here will have some insight as to if tip weighting will work or, if it would be best to place it at 70%. I would of course have to subtract weight from the existing tip weight to maintain proper spanwise CG.
