RE: Goldberg Ultimate Engine mounting suggestions
AirborneSGT. that engine is quite interesting. Your Christen looks great, a friend of mine has one of those. Can't expect Hilton accomodations when you're in the military. I remember those kind of accomodations (RAF U.K.).
Can't go wrong with the CG Ultimate ARF . Any ARF or plans build require somekind of modifications. I will choose the CG Ultimate ARF over having to build it. It is a lot of work building a bi-plane. I've been there. Besides that, the ARF (CG Ultimate) is supplied with better stuff, fibreglass cowl, aluminum landing gear etc..... by the time you upgrade the plan build kit plus the covering it will end up costing more than the ARF.
