The Ho VII Twin Engine Combat Trainer
The two seats were arranged in tandem between the two 240 HP Argus engines, each driving a constant speed pusher propeller, with feathering capability. The retractable landing gear featured two main wheels, and two parallel nose wheels on separate struts.
The aircraft had the same span as the Ho V b, and weighed only 400 lb. more than the V a, but with four times the engine power, it was a potent aircraft indeed!
My brother Walter made the first flight in May 1944, and remained in the test program throughout. The aircraft was demonstrated before Reichsmarshal Goering in an attempt to quell the official distrust of flying wings.
There was great concern about the aircraft's ability to fly on one engine. "Of course it will fly on one" said Scheidhauer, following a single engine demonstration, during which, he was unable to restart the dead engine. "Even in approach configuration can proper directional control be maintained simply by lowering the wing with the running engine. The resulting skid sets up a yaw moment to offset the asymmetric thrust. Why, once when a propeller malfunctioned, and went into reverse, could I land the airplane safely after shutting down the engine!"
My brother Walter, demonstrated the single engine performance to me by circling almost at ground level, both into, and away from the dead engine.
The Ho VII had a new type of rudder installed. It consisted of "tongues" that slid spanwise along the spar, and protruded from the tip for additional wing tip drag. They worked very well, nevertheless the 20 Ho VII's in production at Peschke at the end of the war had conventional drag rudders.
