Pic. 1, Shows cross section of flap. (Note: sheeting gos over LE of flap on top & bottom. Since the LE is not wide enough to go fromtop of flap to bottom, I chose to stop the sheeting at the back portion of the LE. Then contour as shown on plans.
Pic. 2, Show 1st step to build flap
Pic. 3, I elevated the bottom of the flap 1/8th inch so when I contour the bottom of the LE it would match the profile of the bottom portion of the flap.
Pic. 4, Shows the profile of LE and the TE attached.
Pic. 5 & 6, Shows slots to accomodate hinges.
