Description: |
This scale De Havilland 100 Vampire, designed by A J Cockle, was published in Aeromodeller in August 1947, just ten months before the Jetex motors were released onto the retail market.
Its 40 in. wingspan gave it, according to the plan, a 1 in. to the foot scale. Fully sheeted, it weighed 12 oz. ("without rocket"), giving a wing loading of 7.2 oz./sq. ft. A fixed undercarriage enabled it to take off, in Cockle’s phrase, "like a 'Vampire'". It boasted such details as a sliding cockpit cover and (mock) elevator counter-balances.
The accompanying article gave no flying hints and no details of the motor. Indeed the plan describes it as a "petrol driven model", yet has dotted lines in the centre of the fuselage showing the "position of rocket" and an outline of the fused rocket end emerging from the rear of the fuselage. |
