Yeah, good point, Mike. The way the Goldberg ARF's are coming out now, if he in fact decides to get an ARF, they have been coming out somewhat tail heavy. Even the kits are somewhat tail heavy. I've written several posts about my Tiger 120 (not the subject of this particular string, but it applies) and the fact that I needed over a a pound of lead in the nose to meet the CG requirements, and that was with an OS 1.20 AX up front.

A friend built a Tiger 60 and was totally disappointed to have to add a lot of nose weight to get it to meet the CG. And what was with my old OS 61 SF. I think the larger engine is a much better idea considering your point and the CG issues that have been cropping up with the Goldberg models lately. And, it will definitely have plenty of power with the OS 91 four stroke.

DS.
