H.King Armament of British Aircraft (Putnam)


Type 3. A carrier for four 20-lb bombs appears to have been fitted beneath the fuselage of this 1917 trainer, though the makers quoted the military load as 64 lb. It may be conjectured that anti-submarine operation with a 65-lb bomb was envisaged.

The Sage No. 3 was designed in the autumn of 1916 as a primary training machine and was fitted with dual control with a full cut-out gear in the instructor's cockpit. The undercarriage is of the oleo-pneumatic type and has a pair of small wheels mounted on the front Vee in addition to the landing wheels.

THE SAGE MACHINES

The Sage Type 3

  The next Sage machine to be designed was a two-seater tractor intended for training purposes. It was, therefore, designed with a view to good visibility, ease of handling, and low landing speed. As the machine was intended for instruction purposes she was fitted with dual control. The most unusual feature of the Type 3 is the undercarriage, which as will be seen is fitted with an extra pair of wheels in front to prevent overturning when in the hands of a novice.
