I'm building an ultra sport 60 from plans. I plan to compete, eventually, in sportsman class pattern with her. On selecting wood for my wing, what weight range/balsa grade should I aim for with ribs and sheeting to keep her light. I am not planning to build her crash-proof. I have made patterns and jigs to set this bird up, fully expecting to need them in the future. So I want it light, but sturdy enough to compete. I've heard this plane comes out stock around 9lbs. I'd like to keep her between 6-7 lbs. I think this is still a realistic goal. I think I will need to purchase a pump to keep the fuel tank directly on the CG, so there is some "extra" weight that I hate to add, but a necessary evil.

I'll ask about fuse wood at a later point. One thing at a time.[8D]
