Horsepower is suspect, but is as shown in Jane's. Vertical rudder aft could "be converted into a flat plane at will;" horizontal rudder in front also acted as a brake (was that really necessary for 8hp?). Over the top wing was a "mushroom-shaped plane on springs, capable of any distortion, intended to act as a bird's tail does," which Orme claimed would "prevent the sudden plunging of the aerial craft to earth if any mishap occurs." Despite that feature, it plunged to earth on 12/25/08 when a loose wire broke the prop, but news report stated it would be repaired and "the tests resumed." No further word was found.
