You guys are propping the OS .46 with 12 inch props for this plane? Did I miss that or are you running four strokes? I am just finishing one of these but was planning on a 10x6 prop. I want to be able to hover and all that with it with either an OS .46 SF or a .46 FX. Am I under propping this engine for doing the 3D stuff with it? Thanks for any input.
