Very true bob. I don't remember the specifics, but my ultimate was quite a bit lighter than the recommended weight with a very low wing loading. Same goes for the skybolt that I'm getting ready to go do the maiden on. The kit version should be 8.5 to 9.5 lbs, mine is just barely 7 lbs with a wing loading of 17.34 and 6.8 cubed. It should be a real blast with a 120 surpass up front. I'll let you know how it flies later. Steve.
