The engine mount is a really neat contraption and hefty too! I decided to use it for the RCS. The mount is adjustable both ways so you can mount your engine however you like.

I put the engine on the mount and heated up a wire with my torch, then pushed the wire through the engine mounting holes, burning a small hole in the mount where the mounting hole is.

This gives me a clear place to drill and the proper alignment for the engine. MrBonk noticed a slight upthrust in his mount and I have not noticed this with mine. If you have this problem, a couple of washers can be used as shims to take this out.

The cowl is big enough that the engine will fit inside with the pitts muffler. I love the clear plastic practice canopy. Make the cuts you want with that, get it right and then transfer the cuts to the real canopy.
