I believe this is the same gentleman I called early in 2001 and said lightning had hit his welder. I called back in Dec. and said lightning had hit his welder and it might be March , 02 before he got caught up. I was tempted to order one but I'm not sure what the deal is? There is plenty of info on the net if someone wants info including plans. We fly in a cow pasture so noise is not an issue. The turbines are still out of my price range. I built a couple of Schrecklings but havn't had much success with them. The pulsejet seems pretty foolproof.
