Flaps

The flaps are not your usual simple flap that moves from level to down, but the type that moves out, then down. The technical name for this type of flap is a Fowler Flap, it may even be a slotted Fowler flap. The flaps were a little more tricky than I originally imagined. The two types of motion, lateral and rotational, complicate things somewhat, but using runners and a rack and pinion system made the whole system fairly straight forward to build.

The instructions for the flaps comes in two parts. The flap mechanism - which is the actual flap, and the flap housing which is basically part of the wing. Again this is a multi-part model so both files will need to be in the same directory for it to work in MLCAD.
