Thanx for the posts! The U Can Do, I'm gonna try it out on the .46. I'm not into 3D yet, just your run of the mill loops and rolls etc.
I may wind up thowing in a bigger engine in it when I'm ready to. I did notice on the U Can Do that there is a heckuva CG range.
From 2 to just about 4 inches from the leading edge. Probably for the 3D stuff, you'd wanna have the balance at the back end of the CG range.
