RE: How to make sure engine is put on straight?
Cowel fits nice... and it measures 1/4" evenly all around the back of the Nose Cone. The fuse wasn't pre-drilled for the cowel, but the fake exhaust holes were. I lined up those, then made my marks and drilled. I'll have to move the Cowel a hair closer to the Nose Cone so I can take up the gap a little tighter.
