Just as well do the ailerons they will warp after you cover them and each weather change may re-set them for you. I have already tried to salvage the origionals, I was not happy with the results and made the new ones which work well. Leave enough gap to allow really high deflection w/out pulling the hinges out, just a tip I remembered. Have fun....12.25x3.75 apc prop. should be just the ticket?
