OMP FF540P engine?
Termagator test flew my OMPFF, with an Irvine 46. Did everything I can't do. The only reason I went with the 46 instead of the new 39 was I needed the nose weight. Termagator wanted to move the engine back to the next set of motor mount holes that I had put in so I could move it back if needed. We ran out of time. Hover, harrier you name it.
