Should this post be in the helicoper forum? <sarcasm>

Neat concept. I have a home built stand too, but it's optimized on accomodating one engine at a time, but with an easy and flexible set up for each. It's a one foot square of plywood, with a few 2x4's screwed down and I clamp down on the case lugs. While I'm impressed with your stand, I am more envious of the number of engines. Nice!
