Thanks guys for your input. That makes me feel much more at ease. I just checked it again, and appears that I will only be moving down about 1/2" max. I think I'll give that a try. Its only a plane. I can always build another if something goes wrong. At least it wouldnt be getting a virgin. I've rebuilt them before. In fact, I have always contemplated folding up one of those plastic sacks you take your groceries home in, and put it in the tail of the plane when I build it. Then I would be able to carry the plane home easier if something should go wrong. Or is it when something goes wrong. thanks again for the input.
