The flaps and ailerons are the same size, 15.625" where they attach to the wing.

todhog,
I spoke to my LHS today about G26 starting problems. They said they have seen cases where the throttle butteryfly is rotated 180 degrees from where it should be. If you look in the carb, you should see the threaded end of the screw holding the butterfly plate to its shaft. If you see the screw head, it needs to be rotated.
