RE: PROP SUGGESTION - .60 SIG HOG BIPE
Hi!
Yes! A 15x4 APC will work just fine. I use that prop size on my Great Planes "GEE BEE R-2" powered by a 15cc two stroke.
I even use (Best prop for it) a 16x4W APC on my You-Can-Do .60 powered by a MVVS 15cc (.91) two stroke using 5% nitro and 15% All synthetic oil.
