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.
?? he's asking about a 91 4 stroke
My experiance is that 4 stroke engines really don't like to spin up that much,, that's why I never run less than an 8 pitch with mine

Well,,,
I don't think a Hog Bipe will ever be a 3D machine,, but I like to run a 13-8 on my 91 4c engines
good luck
I agree that it is not an ideal 3D plane. Just a good intro bipe for me. I am going to purchase either a 100cc Ultimate, Python or Beast. This was just one to get my feet wet. Even in knfe edge it takes so much counter aileron it is just not the best plane for serious 3D but I do like to try. I think that being able to pull off ''tricks'' wtih a plane that wasn't designed for them really build some skills. ( like hovering a cub for example). I appreciate the input. Anythoughts on a bigger 4 stroke like a 1.20? Obviously throttle managment will become much, much more important with that set-up but it may be the solution for my verticle issues.

I guess yes, if you want to fly 3D you need at least a 2-1 thrust to weight ratio,, what does the plane weigh?
