Just a hunch but I'm guessing the rear spar location, being behind the CG and CL, might have a bit of a stabilizing factor over the forward spar location which is directly on the CG location. Then again, it may have a bit of de-stabilizing factor with the turbulence it creates. I guess that's what testing is all about. Larry Flesner
