Wing construction is standard built up balsa and ply construction. Light ply and balsa make up the ribs. Stringers are balsa squares, sheeting is 3/32" contest grade balsa sheeting to save some weight.
After the basic bones are laid, the top is sheeted:
Retracts are fitted and installed. The retracts are Down and Locked electric retracts.
To accomodate wires for lights, servos and pressure tubes for a functional pitot tube, conduits were placed inside the wing structure that will go from servo bay to servo bay. File folder paper was used to make the square conduit (wing tip to aileron servo) and round conduit (aileron servo to flap servo) . The tubes for the pitot tube are Sullivan Golden Rods. The telemetry module for the airspeed sensor will be located in the same compartment as the left aileron servo. So the Golden Rod goes from the end of the left wing to the aileron servo compartment. The botom center is then sheeted. Ailerons are going to be attached with Robart point hinges, so blocks are installed at the trailing edge to accept the hinges.
With the internals complete, the bottom is sheeted. "Mail Boxes" are cut into the top and bottom sheeting on the wing tips. These slots were used to reduce the stall speed of the plane. The slot ports the low pressure on the bottom of the wing to the top surface to keep the boundary layer on the top of the wing attached at high angles of attack. This was used in order to help with short, low speed landings (i.e., carrier landings). Wing tip mounts for the navigation lights are installed, and openings for the formation lights on the top of the wing tips are made to communicate with the installed conduit. After sanding, filler was used to fill in scratches and dents.
The center fairing for the belly is made from balsa, shaped and installed. The center slot is then open for the bomb release mechanism for the belly bomb.
The wing was then covered with 3/4oz. fiberglass and Zap Epoxy resin. Fiberglassing added approximatley 2.5oz to the wing. The Dauntless carried a 1000lb bomb in the center of the wing and a 100 lb bomb under each wing. Bomb release mechanisms were made from G10 fiberglass to bolt into each location. Bomb stabilizers for the 100lb bombs were made from brass rod and are spring loaded so that they are functional. The following pictures show the release in the open and closed position:
The wing mount for the bomb release is angled to match the wing diheadral:
The center release uses a similar principle as the wing releases, except that the center bomb stabilizers are different and therefore are not part of the module.
For the airspeed sensor, the Frsky airspeed module is used. However, the pitot tube that comes with the Frsky module is way too small to look scale. Additionally, the actual pitot tube had a fin on the top of the assembly. Therefore a pitot tube was fabricated from brass tube, balsa and body puddy to create a functional ptiot tube that will also look scale when installed. The front part of the pitot will be painted aluminum, the rear portion (starting behind the fin) will be painted the same as the underside of the wing.
