Lightwing Rooster II

leeroost2


The Rooster2 is John Lee's two-seater and, although it looks totally different from the Rooster 1, it uses similar constructional techniques and materials, and its steering arrangements are also similar; braking, however, comes not from a nose skid but relies solely on the air resistance of the thick-section wing. Along with its 'boxy' fuselage, the thick wing section (entirely a John Lee creation), the aircraft is fitted with a Robin EC44 engine which, because of the engine's position, is mated to a smaller-than -ideal prop. Conceived largely as a trainer, the Rooster 2 has a certain degree of flexibility built into its construction, to enable it to cope with bad landings by inexperienced pilots. The thick cantilever wing was chosen largely to simplify construction - it eliminates the need for rigging wires. While the aircraft can be re-rigged for trailer transport, portability is not a high priority. This aircraft does not in anyway pretend to be car-toppable.
Tandem two-seat single-engined low-wing with conventional three-axis control. Wing has unswept leading edge, swept forward trailing edge and tapering chord; conventional tail. Pitch control by fully flying tail; yaw control by fully flying rudder; rod control by fully flying rudder; roll control by 40%-span ailerons; control inputs through stick for pitch/roll and pedals for yaw. Cantilever wing; wing profile; 100% double-surface. Undercarriage has two wheels with tailskid and nose-skid; no suspension on either wheel. No ground steering. No brakes. Wood fusel-age, partially enclosed. Engine mounted above wing driving pusher propeller.
