Wing/pylon assembly

Note: this step may be eliminated from production kits which may come with pre-drilled wings.

Test-fit 1/16" ply pylon reinforcements (the last remaining laser-cut parts) to wing tips and mark the locations of all 5 holes on the wing. With a sharp needle, mark 4 pilot holes for the #0 screws that will hold pylons to the wing. Using a 1/4" bit, drill a hole about 3/16 deep. This hole is needed to accommodate the protruding lower end of the rotor shaft. There is some up-down play in the shaft. The hole you drill must be deep enough to accommodate the shaft in its full-down position (its position at rest). The shaft must spin freely even when it's fully recessed into the pylon, or friction will make it difficult for the rotors to spin up.

Glue the 1/16" reinforcement on the wing.

Using #0 screws, fasten the gearbox housing (pylon) to the wing.
