About this Plan

Howard GH-1 (DGA-15). Radio control scale model. Wingspan 84 in, wing area 1081 sq ft. Scale is 1/5.4 (18%).

Quote: "Constructions Manual: United States Navy Howard GH-1 (DGA-15). This is a 18% sport scale model of a WWII era light personnel transport aircraft manufactured for the US Navy by Howard Aircraft Corporation, Chicago, Illinois.

Before the war the Howard DGA-15 was one of the finest, most powerful light aircraft available in the USA. While the fuselage was constructed of rectangular steel tube, with some areas being sheeted with aluminum, the wings were constructed largely of wood. The entire aircraft was fabric covered.

Dimensions and Specs were as follows:
Wingspan: 38 feet.
Wing Area: 210 sq. ft.
Fuselage length: 25 ft, 8 inches.
Speed at sea level: 192 mph.

At 18% scale the model has a wingspan of 84 inches, or 7 ft, and a wing area of 1081 sq in, or 7-1/2 sq ft.

The plan for the Howand GH-1 model was drawn primarily, from a set of 3 views with text and a photo which is available from Bob Banka at Scale Model Research, 2334 Ticonderoga Way, Costa Mesa CA, 92626. The 3 Views also include Specs, dimensions and color notes.

CONSTRUCTION: Before you get into actual construction I suggest you cut out all the parts you need for whatever major assembly you are going to be working on In this way you will not have to stop construction to cut out parts.

Also it is important that you build 1 degree of washout into each wingtip (leading edge down trailing edge up) during construction or covering. This tames the stall gulte a bit by causing the center section to stall before the wing tips.

FUSELAGE CONSTRUCTION: Onto the 1/8th inch lite ply sides assemble and attach the 1/4 x 5/8 inch hardwood uprights in the cabin area. Bevel the 1/4 x 3/8 inch balsa strip uprights and install onto the fuselage sides at F,G,H and I. Be sure to make a left and right side, rather than two of the same side! Install the cabin top ribs onto the hardwood cabin uprights. Drill out the holy hole in the cabin upright at C.

With the sides upright over the plan top view, install bulkheads at B, C, D and E, Look for the locations indicated by the symbol. On these lines you are going to score the lite ply sides vertically about 1/3 the thick ness of the wood. Of course you will want to use a metal straight edge and exacto knife to make this score line..."
