SW - Mann and Grimmer M1

In the year 1914, the synchronization between gun and propeller hasn't been developed yet, so the two young British modellers, R.F.Mann and R.P.Grimmer found a bit strange solution of this problem. Their two-seat fighter prototype had a radial engine placed in the nose, but with two propellers driving behind the wings, in a pusher configuration in order to give the gunner a good field of view.
The prototype was completed at Hendon Aerodrome in February 1915 and made its maiden flight on 19th February but its complicated chain drives created some problems and underpowered the engine. When it was expected the prototype to be tested by the Royal Flying Corps, it crashed when landing after trying to beat the British altitude record on 16th November 1915.
Mann had designed an improved version, the M.2, but the lack of funds made it impossible its creation.
