majortom,

Myself took the extra expense of ordering contest balsa for all the sheeting and AAA for all the leading edges. Lite ply to replace the fuz sides. I will have to dig up a digital scale myself to see if it was worth the extra cost and to play the matching game.

What was the materials weight that you are going to swap, and what is the all up weight of the new material. Hence what is the weight gain going to be on you flier?
