Iron On ?
Too many options. Are you setting up a trainer or 40% aerobatic plane?
Iron on hinges (monokote or equivalent) are OK for small planes but not for larger ones. "CA" type hinges work well up to 60 size planes in most cases however pinned hinges are preferred for larger planes.
I personally like the ease of "CA" hinges but much prefer the function of pinned hinges. As your flight skills improve the hinges lasting longer is a definite plus.
