However, you will still have the prop turning in one direction and fuselage trying to turn in the opposite direction.  I would bolt a wooden "fake" spar in main spar slot with at least a couple of bolts each side and I would anchor the left side (sitting in pilot's seat) to a ground tie down with a rope.  That would ensure that the CW turning prop (sitting in pilot's seat) would not be able to turn the aircraft CCW.

That would probably be the safest thing to do, but I just can’t imagine that it’s necessary.  I’m hoping that we have a few people here that can say they ran there’s with no problems.  Todd recently ran, and I assume it’s without the wings, but he’s got that training wheel <G> on the front, so it might be different.  I know Tracy said he ran his numerous times in his neighborhood, before first taking it to the airport, but I didn’t ask about the details. 

I don’t plan to do anything more than make sure everything is working while running it at home, so I’m not going to be blasting full throttle or anything. 

Good Luck!  Is this with turbo on or not?

Ha! It has been hard to keep up hasn’t it :-)   Roger, turbo- manual wastegate, relief valve currently set at 1.5 psi.
