A V Roe's Roe 1 Triplane, July 1909. This machine ("...with self aboard" as Roe put it when writing to Flight in June 1909) weighed 400lb and relied on just 10BHP from its JAP motorcycle engine. Roe tilted and twisted the main planes of this machine for control. "I usually run along with main-planes at a slight angle; this allows machine to gain speed and the tail to rise; on increasing the angle of main-planes to about 10° the front comes off the ground, but owing to insufficient thrust it soon comes down again."
