The following photo and description is from Frank Beafore of Select Tech GeoSpatial. Frank has become a modeling enthusiast and UAV manufacturer as well. It appears to be an example of the first ever electric powered RC helicopter that was manufactured for general sale to the public. It’s an interesting unit. If you know more about it or the history of hobbiest early electric helicopters, please stick in a comment.
Attached is a photo of the first electric RC helicopter offered to model builders back in 1981. It was manufactured by Ishimasa Co, LTD, Tokyo. It used NiCad batteries with less than a 2 min. flight time. To train on it, you needed a 25 foot umbilical to supply current to keep it going. The tail rotor was coupled to the main drive via a fragile rubber belt that broke in mid flight. I do not think that it was 3-D capable.
I was lucky to get all the spare parts and the original instructions.
