Rick,
I had great results placing the ailerons (pinned) on the wing, then sliding the Pheon Decals into position and cutting them at the hinge line once in place and "blotted down". The extra overhang then dropped down into the opening between wing and aileron with just enough "wraparound" to look complete.
I need to get a few photos onto my Build Log, the decals worked great.
Cheers,
Lance
