THE MODEL

Airborne's Skyfox is a 1/5 scale model designed for a .35 - .40 motor. Outlines are shown for the Kitfox nose area for those who prefer the original version. If the full sized aircraft is an ultralight then the model is an ultra feather weight! It's nothing but sticks with a thin covering, plenty of wing area for a tiny engine to pull it along.

As with the full size Skyfox the model is not intended for aerobatics. The aerofoil used looks like something from an Old Timer model. Relaxed, slow flying or touch and goes is probably as much as you can do with this model. Despite its impressive slow flying characteristics the model Skyfox should not be considered a trainer. BUILDING THE WING Unlike the full size Skyfox the model does have a decent sized spar for the wings. Cut out all wing ribs, riblets, leading edge and trailing edge to size. Check size of servos you intend using for the ailerons. Mini servos are recommended but standard servos might just squeeze inside the inboard wing. Cut slots into the trailing edge for the ribs. Prop up the spar over the plan by 5mm and the underside front edge of the shaped trailing edge by 1.5mm. Pin to the building board. Cut out a section from the rear of the leading edge at the inboard wing to allow for the brass tubing. Pin the leading edge down onto the board. Glue all the ribs into place from W2 - Wing tip. Bind and epoxy brass tube, crimped at outer end to ply plate WP then glue into place together with W1. Glue in the rear brass tube also crimped at the outer end. Add riblets R1 over WP, then glue the remaining riblets R out to the wing tip. Allow to dry. Add the balsa wing tips, carve to shape. Note the different depth of the downturned wing tip plates of the Skyfox compared to the Kitfox. Sheet over the inboard wing between W1 - W2. Add the plywood strut supports.
