Gullie (oz3707)

About this Plan

Gullie. Free flight sport model. Here's one from 1963 Model Aircraft: The Gullie.

Quote: "Colin Read's exciting 50 inch free-flighter for 1-1.5 cc. Gullie.

GULL wing spells models have a fascination all their own, so it is surprising that one does not see this attractive layout more frequently. Gallie is the result of much experiment with parasol and gull wing designs, built in various sizes over the course of several years. It is big enough to accept single channel radio, but also makes a tough, stable, free-fighter that is exciting to fly, with its fighter-like lines and racy per-formance.

No attempt was made to build a light-weight model, everything being solid and with plenty of sheet covering. Although I covered the original in orange jag tissue, silk or Viscotex would be beam. Viscotex can be dyed any colour, using nylon dye of a good quality, orange being good for visibility.

Construction. Commence by cutting out the fuselage sides and formers, then build up u/c former F.2. Upon the choice of engine will depend the spacing of the cut outs in F.1 and F.2, any 1 to 1.5 cc diesel or a low powered 2.5 cc glow motor being suitable. Araldite the engine bearers to F.1 and then cement both fuselage sides and u/c former F.2 in place, afterwards adding formers F.3 to F.6. When dry cement together the fuselage sides at the rear and add the remaining formers.

If a separate fuel tank is to be used, this should be cemented firmly in place at the rear of F.1 between the engine bearers and level with the jet assembly of the motor used. Be sure to fuel proof this bay thoroughly.

The upper and lower surfaces of the fuselage are now covered in 3/32 in. sheet; strips 1/4 in wide being used to plank the curved portions. Cement the cowl sheeting temporarily in position and sand to shape, then remove the cowling and carefully make the cut outs for the engine controls. Several coats of dope will be required to prevent fuel seepage..."
