Modelul avea radio cu lampi si iesirile cu relee. Rudder-ul era actionat cu un electromagnet:
"The job of managing director at ED was taken over by Jim Donald, one of the original seven, and on September 21, 1954, inspired by the success and publicity of the Channel crossing by a model boat, ED undertook a further promotional challenge, the crossing to France, non-stop, by a radio-controlled model aeroplane. The aircraft, powered by an ED 3.46cc Hunter, was a Radio Queen, ED's one and only model aeroplane kit, had been designed by Lt Col HJ Taplin. The radio equipment was the latest ED 3-reed receiver with rudder control operated by a solenoid. The third channel adjusted a trim tab through a Mk 3 escapement. Standard ED 3-reed transmitters were used, one on the ground and one operated from an Auster which followed the Radio Queen for the crossing. Extra fuel was carried in the wings of the model to maintain balance throughout the flight. At 13:35, following a successful and athletic launch from a field appropriately named Bleriot's Meadow, climb-out was controlled by one of the famous names of the day, Mr Sid Allen. Control of the heavily laden aircraft was then handed over to Honnest-Redlitch in a circling Auster which would follow the model during the flight. After crossing the French coast at 14:15, the plane had achieved its maximum height of 3,100 feet and was turned on course to Calais Marck airfield. On arriving over the field at 15:17, the plane was spiralled down to 800 ft and the Auster rapidly landed to regain control from the ground. Unfortunately, by the time the Auster had landed, visual contact with the model had been lost and it was last seen heading toward the south-east, flying in wide left hand circles. The Auster was once again scrambled to try and locate the model but without success. However six days later the model was found by a farmer in a beetroot field at Guemps, about five miles from Calais harbour[12]. It should be recognized that this achievement was accomplished using the vacuum tube radio equipment of the day, with an overweight model powered by a 3.46cc diesel engine. In this day and age power would probably have been a 0.60 cu in (10cc) glow-plug engine."

Prima data am citit despre acest zbor remarcabil in "Model Airplane News" din ianuarie 2004. Apoi am citit ca titanul care a construit modelul era aproape orb si surd. Modelul este creatia unui geniu. Cu un motor de serie a facut 1 882 de mile cu mai putin de un galon de combustibil. Va las sa cititi articolul. Il trimit lui Radu prin mail pentru ca sa-l puna el la o rezolutie rezonabila. Mai multe informatii puteti gasi cautand dupa: Tam 5 Si dupa numele autorului: Maynard Hill.
