I got it finished and flew it today. I put the servos in the tail and it came out tail heavy. So far I've added 5oz of lead to the nose and it still balances about 1" behind the back of the CG range.

I could tell flying it that it was tail heavy too. It was very pitch sensitive and not at all comfortable to fly like that. I'm gonna have to shift some things around a bit to get the CG correct. I hate adding dead weight for balance. Because of the gasser engine I'm leery of shifting the R/C gear forward due to the possibility of interference from the ignition. Will try it again tomorrow with a few changes.
