Keep at my friend,

I managed to build the GP 40 size Cap at 4.27lbs.

Everything was done with weight reduction in mind. The first thing I did was to throw all of the wood away and replaced everything with contest balsa.

For your spar you should of used lite balsa square stock and 3M'ed a piece of uni carbon on the outside edge. When you lay down your sheeting, you just use thin CA and it wicks through the uni and makes the sheeting/uni/spar a soild piece. Very strong, very lite, very easy!!!

I ran a LA 40 ( super lite engine)with a Macs pipe and Nomex honeycomb firewall, and at this weight it had complete unlimited vertical. I used Hitec 225's on everything but throttle, which was a HS-81. Used Spider Wire for the Pull-Pull and had Stans Fiber Tech lay me up a single layer carbon cowl.

It took about three months to complete, but was well worth it.
