Roe was experimenting at Lea Marshes with a triplane of rather curious design the pilot having his seat between two sets of three superposed planes, of which the front planes could be tilted and twisted while the machine was in motion.
Mr Roe's triplanewas chiefly interesting otherwise for the method of maintaining longitudinal control, which was achieved by pivoting the whole of the three main planes so that their angle of incidence could be altered.

Their requirements are great lifting power and great stability, and these, the triplane with its extra lifting surface, best fulfills.
His distinction in the pioneer days was that he managed to make his triplane lift into the air and fly a short distance, with the aid of a motor-cycle engine developing no more than 9 h.
For some time he was an advocate of the triplane form of machine--a craft, that is to say, with three main-planes fitted one above another.
