All Wing Wonder (oz3718)

About this Plan

All-Wing Wonder. Control line speed model for .049 engine, drawn by Paul Del Gatto, 8in wingspan, from Air Trails Magazine July 1953.

Quote: "HALF-A DELTA SPEEDSTER. All-Wing Wonder. For the new small speed contests Paul Del(ta) Gatto offers a quickly constructed 'futuristic' craft.

Now that the Half A speed event is a recognized one, the classification promises to be a hotbed of activity this season. This delta wing model represents less than twelve construction hours. If the model is built light and care is exercised in the construction and finish, your speed with an Atwood .049 should be in the 85 mph range.

At first glance the model's compact size and unusual wing structure may give the false impression that it is tricky to build. That just isn't so as you will see when you get under way with razor blade and sandpaper.

Begin with the fuselage. Cut out the 1/16 plywood ring (F-1) and cement to the blocks before carving. Carve to shape the blocks for the upper and lower shell. When the approximate shape is obtained, cut away the section on the upper shell which the engine will fit. The 3/32 plywood firewall is cut to shape and both the upper and lower shell are notched to receive it.

The cowl is made with two side pieces and one top piece. Cement the two side pieces together temporarily until the external shape has been obtained; then pry apart and carve out to the desired inside shape and cement to the upper shell. The top piece or 'cap' is shaped and cemented in place to complete the cowl.

From a piece of sheet balsa, shape and sand the rudder. Notch the rear of the upper fuselage shell to receive the rudder and cement firmly in position.

Start construction of the wing by cutting out the ribs and constructing the leading edge as indicated. After these preliminaries lay out the wing plan as you would any other. The leading edge is not cemented in place until the hard-wood spars have been inserted through the ribs. When the wing frame is completed, install the bellcrank and wire guide assemblies in place.

The upper fuselage shell is severed into two sections just aft of the cowl; the forward section..."
