When I helped out a nearby school with their TSA Flight Endurance event, my plane was the only one with a underslung stab. All the others were built with the stab on top of the boom. The one guys plane flew amazing even better than mine. Ana again I dont know why.

I fly with stab on top of boom, and other than the difficulty in assembly, I prefer it to the underhung stab. I have no scientific explanation for why it is better, I just like the look.

Joshua,
I've never seen a plan of Larry's F1D. However, I know how much a wing of his weighs. I did a really sweet patch on his wing tip when I was junior TM in Serbia in 2008. At the 2010 USIC, Larry broke a motor on the same plane which totaled the wing. Since the patch was still there, he gave the wing to me. I went down and weighed the wing and it was 0.29 g, albeit with 1/3 of the front wing spar missing. This weight also is not surprising given that he uses Y2K2, which gives about a 38-40 mg weight advantage over OS on a F1D wing.

If you strike out on published plans, maybe ask around (privately) for his phone numb, and he might easily rehearse or recommend weights. If LC is still flying what I recall seeing circa 2004, it was conservative design, and no one would go wrong to copy any aspect. (For example, stab on top of boom, one of mine flies fine that way, but's it's seemingly out of vogue.)
