Wow, an .82FS on a 4*40 - that should really move! I only have a .91FS on my 4*60 and moves pretty well.

Gene, I think the counter balances are a good idea personally - it will be interesting to see what effect they have on the plane, especially knife edge. I'm probably going to build a 4*120 sometime in the next year and want to incorporate all the things I've learned from the 4*60, plus all the ideas of others (like the counter balances) into the plane. Now I just need to decide what engine to use on it (maybe a YS 140 sport?!).
