I run an APC 11-4 on my Jett .46 in a fun fly plane. As long as you keep the top end RPM at 16,000 or above it runs great. Dont overprop it. The Jetts are not made to lug big wood (or plastic) slow, but then again if thats what you want to do go with a 4 stroke.
Exactly how fast is your Jett .46 spinning an APC 11x4? My MVVS .49 spins an APC 12x4 at 15,000 rpm. A quick calculation shows that you're Jett would need to spin over 17,500 rpm in order to match the thrust...
