I agree with almost everything cabane said! I had forgotton about the laser cutting. I found it to be less than exact, and a pain to seperate the ply pieces.

rcman: The Seduction is smaller, and of lighter construction. I don't think you'll save any weight by cutting out a little bit of balsa on the 3D. It's got a VERY long lite-ply fuselage.

Remember, I sheeted my stab with 1/16" balsa and built the elevators out of firm 3/8" sticks. So you could save an ounce if you went stock, but fly it gently if you do. The sheeting is all pretty beefy, so I guess you could go to 1/16" light wood there. If you know how to land, as opposed to a controlled impact, you could get away with 1/8" music wire gear. And if you used a light 2-stroke that would save an ounce or three. But that YS is so sweet!

I'd like to scratch one out of contest grade! You could make way under 5 pounds easy.

Regrets? Wish I would have sprayed the interior of the canopy silver and stuck the tank on the CG. And sprayed clear poly on my custom graphics! YS 20/20 is hard on them, and it gets everywhere!
