So the next step was the wings. I used 400mm length servo extensions for the flap and ailerons. The gear and brakes were included.

The aileron servos are typical door/cover mounts. Minimal work was necessary to fit the Futaba servo. I aeropoxy carbon over all of the horns. I used SeCraft 20mm servo arms (2mm thick) with 2mm pin holes. I replaced the stock 1.6mm MPJet connects with 2mm pins as I couldnt find any horns with holes less than 2mm.

The flap servos were a bit more difficult to get too. I had to use the Dremel attachement and chuck to be able to get a drill into the wheel well. Some work was done here to open it up to accept the Futaba servos. Although not final, this was the basic geometry I was looking for for the flaps. With the flaps in the down position the servo arm is full extended so the load is minimal to the servo motor.

The retract bays were painted black and coated with a finishing epoxy for waterproofing. There was already a glass covering some of the critical parts on the l/g blocks.
