I did a little more research on the C-26 and discovered I have to really cut the cowl up alot[]. I don't mind to much having to cut the side for the carb but, to have to cut the other side as well? I know it will be hard to find an engine that will fit in the cowl but I really don't want to cut it up to bad. The YW will fit in the cowl with just the velocity stack sticking out.

Birddog-RCU I don't want 3D or anything like that but I have discovered that having some extra power is nice to get yourself out of trouble. I even found some pictures of a Rascal 110 hovering a few inches off the ground with a G-26. The reason I was considering the YW-48 is because it is lighter than a G-26 and those cylinders would look really good sticking out both sides of the cowl. I figured I could throttle back or even program in a governor in the transmitter. I don't think I will actually go for this engine though.

I really don't want to cut the cowl so I think the Zenoah is out.
