RE: what 35 % is the best for 3D
For 3D I like the Edges. They have few if any bad habits in very slow flight. For tumbles and spins it is hard to beat a CAP. The Extras fall in the middle.
If you want 3D look at the Edge! I like the flight of the AeroTech and the Carden Edge. They are very sturdy and can take a lick and keep on ticking, most of the time. If you go with these you won't go wrong. If you are a "builder" the Carden is a great kit. If you "can" build the AeroTech goes together much easier being all laser cut. Both of these birds fly great at 28-30 pounds with a 100cc twin on the nose. Some people are totally hung up on being the lightest, it may help the wing loading but it has its trade offs as everything does.
