DH 110 (oz2746)

About this Plan

D.H. 110. 38in span scale C/L stunt model, from Model Aircraft magazine, February 1956.

Quote: "A scale control line D.H.110 which is a stable flier and a fine stunter.

STUNT models have been my main interest for about four years. Most of them were just profile jobs, but I tried to develop a model that had a high speed, would stunt readily, and yet be rock-steady inverted. l succeeded in my aim, and had quite a few Northern contest successes.

Once I knew what the essentials were for a good stunter, I designed the model of the DH 110. It makes no pretence at true scale, but in the air deviations from true scale are not readily apparent. It flies at more than 60 mph with a good PB Amco on an 8 x 8 prop. It is smooth to stunt, and punches straight through wind gusts when inverted.

Wing: This should be built first, as everything ties around this member. The wing ribs are cut on a line level with the bottom of the trailing and leading edge, so that the wing can be built flat on the board. The top spars are glued in position, and the whole wing left to set. After removal from the board, the lower half of the ribs are cemented in place. The tank must be fitted next, before the bottom spars arc added.

Now the two fuselage bulkheads are cemented in. A wedge-shaped piece of balsa across the join of the two 1/4 x 1/8 in spars will provide a good setting for the rear bulkhead. After this construct the two booms and cement them securely to the wing ribs and spars, making sure they are lined up properly. Next, shape and cement the fins in place.

The elevators are hinged to the tailplane with nylon. Care must be taken to ensure that the tailplane is lined up properly with the wing, when it is cemented in place on the fins. I suggest using a simple cardboard jig..."
