All the debold RC designs from that era were basically the same model scaled up or down. I still have a Livewire Cruiser that I built in 1956. I think it was the largest of the Livewire series. I bought it because it was large enough to contain the radios I was experimenting with. It had rudder, elevator, and throttle using pulse proportional single channel radios drivng Southwest Magnetic actuators for rudder and elevator and a three postion escapement for throttle. I was also experimening with ways to add ailerons but never got it reliable enough to fly. Probably why it survived.
I did use it to check out my first proportional Microavionics radio in 1967. It has been in the attic ever since.
