Heheheh

Another wing ? flap question ...
I'm building Brodak's "Oriental" and have followed the plans and instructions to a "T".
I'm ready to fit the flaps , but there is a fit problem .
The trailing edge of the wings (with trailing edge sheeting) is 3/8th's of an inch , but the flap material is only 1/4 inch thick .
I'm using barrel type hinges , not the cloth supplied .
The problem is , there is a noticable "step" from the wing TE to the flap hinge .
Should I get some 3/8th balsa sheet and redo the flaps ?
the 1/4 inch flap material just doesn't look right to me

First of all, what do the plans show? I've done elevators smaller than the stab, but not flaps. It might work just fine. But if your in doubt,
use 3/8 stock for the flaps.

A lot of folks use 1/4" as flap material....there are thoughts that the larger wing root verses the 1/4" flap will "wash" the surface, and correct some hunting issues.

the sheet for the trailing edge is tapered the last 1/4inch to match the flap had the same on my kit

Rob: Check your plans and on the side view of the wing you will see the taper on the trailing edge sheeting.
