Im back guys! My newest build the Siemens-Schuckert R.VIII, was a german bomber type aircraft from WWI, this plane had two puller and two pusher propellers, mounted between the mainplanes, by leather cone clutches combining gearboxes, shafts and bevel gearboxes. Two aircraft were built but only the first, R23/16, was completed. Ground trials commenced in 1919, after the armistice, but were interrupted by a gearbox failure which resulted in a propeller breaking up and causing extensive damage. The second airframe, R24/16 was never completed and the first not repaired after the ground running accident due to the Versaille Treaty restrictions. At the time of its completion the Siemens-Schuckert R.VIII was the largest complete aeroplane in the world.
