Well, I moved my cg back to 4.25 yesterday and flew it before the rain came. Doing that made quite a bit of difference. Inverted flight takes very little forward stick and knife edge mixing was all removed. It will still pull to belly a tad but not enough for me to worry about. I was going to try my first low inverted pass and touch the tail on the runway, but now that it's flying like a totally different plane I dont want risk it. Harriers still no improvment, maybe the saito 91 is just to much wieght for those little wings. I think I'll try 4.50 and see where that gets me. You guys running yours at 5.0 how stable is it?.........Dave
