I can attest that the extended wings add to the climbing and aglity of the plane. It also is a lot more stable. You lose a bit speed, thats why I havent done it yet. However it is still way, WAY faster than when the wings were in the lower position. (out of the box) The loops that it is able to do out of a stall, with the larger wings, is pretty badass. If bigmilo wasnt so lazy he'd go to his OWN OFFICE and get his video camera and tape this stuff. His office is really far, its like 2 doors down.....
