Type Description

• Mosquito Mk.1
• Single seat open cockpit gyroplane, the fuelage of which was a simple structure of high strength alloy and steel tubing and featuring a stepped keel and a glass fibre fairing. It was fitted with a two bladed auto-rotating, semi-rigid main rotor of laminated birch, reinforced with a steel spar at the root, and with a cyclic stick for rotor control. The tailplane comprised a horizontal stabiliser, fin and rudder of resin bonded glass fibre ribs and panels. One 1,500 cc. Brooks modified Volkswagen powerplant.

• Mosquito Mk.2
• Production version of Mk.1, with straight keel, no horizontal stabiliser and conventional stick controls. One 1,600 cc. Brooks modified Volkswagen powerplant.

• Hornet
• As Mosquito Mk.2 but featuring a gimballed rotor head. Originally designated Mosquito Mk.3.

Production Summary

Notes

The actual c/n and registration tie up for the Brookland machines is extremely unclear, but the following notes summarise this authors conclusions.

1. G-AVHC was the second machine registered and the second to fly. This could mean that, although c/ns were allocated to the machines at some time, they did not necessarily reflect build, or at least completion, order.
2. The CAA at G-INFO [3] gives this as c/n 4; Ellis [2] gives this as c/n 2, which is more logical given the registration dates.
3. Ellis [2] gives this as c/n 3, which is logical.
4. As no other French registered Mosquito is known, it is still possible that c/n 7 became F-WMEF, with c/n 6 unknown.
5. C/n 11 would appear to be most logical as this is a Mk.2, but see note 6.
6. In 1978,Tony Phillpots acquired various components enough to complete nine Brookland gyroplanes. These presumably are machines c/ns 9 to 17. Four aircraft are positively identified (c/ns 9 to 12, 16 and 17). Two further machines were produced from Phillpots' acquisition:
   G-MIKE, c/n MG-1, recorded in G-INFO as built by Gyroflight in 1972. Regd to Michael Howard John Goldring, Newton Abbot, 1978. G-MIKE, c/n MG-1, recorded in G-INFO as built by Gyroflight in 1972. Regd to Michael Howard John Goldring, Newton Abbot, 1978. These presumably account for two of the three c/ns13-15, the third remaining uncompleted.
