1) Wing Span & chord:
Go by the name of the plane, not
the wing span. Over the years it has been entered 2 different ways.
Some measurements show the actual wing span of the plane, some show the foam
only, no wing tips. This can make a big difference. Use the wing span as a
reference only. Same thing for the chord, some are the chord of the foam
only, some are for the finished wing. It's easy for this to happen, since
the list goes back about 40 years, and through 3 different owners. This is
slowly being remedied.
2) Pieces:
* If present, this tells the
number of pieces of foam make up the wing. The vast majority are 2 pieces,
one left and one right. This is standard.
* 3 pieces means there is a
center section, and two outer panels, That is used on planes where the center is
flat, and the outer panels have dihedral.
* 4 or more pieces is for planes
like a mustang, where there is an inner panel that has a Leading Edge Extension
(LEX) and the outer panel has a different sweep, like in the picture below.
There may also be a center section. A lot of gliders are this way also, although
not as drastic.
