I'm in the process of a complete rebuild for my PA12 and am putting on PA18 flaps. The original had PA14 flaps but the paper work described PA18 flaps. As most may know PA14 flaps are 65" and come up to the end of the wing. PA18 are 62.5" and would require a 3" fairing. My question is, since I'm building the flaps should I stay with the standard PA18 at 62.5" or build them as extended PA18 at 65". I would appreciate comments on possible tail flutter with the wider flaps.
