If you have already built the wing, I would seriously think about cutting it, and using ailerons, you do not want to fly with 3 channels. Alternatively, don't cut the wing, but install the Ailerons, it will be a much better flyer.

If you are interested, I have a spare PT-40 "Sport" Wing, it was given to me by a guy who planted his PT-40 and trashed the fuse. It is yours if you want it. I am not sure where you live, but if you cover the shipping from Toronto, you can have the wing.

Feel free to PM me if you are interested.

Cheers!
