FHHuber, I realize that the Kadet is a relatively new design. What I meant was "if the Kadet had existed in those days, it would have been powered by a 29-30 size engine". In the fifties, I had an airplane called a "Buzzer-D" that was of similar size and characteristics to the Kadet. It had a home built WAG three tube single channel reciever that worked a rubber band powered escapement to actuate the rudder, and was powered with a Forrester 29. The transmitter was a large ground based unit with a nine foot antenna and the control was a pushbutton switch on the end of a chord. A push of the button would swing the rudder full deflection and it alternated with each push. As primative as it sounds now, we thought it was wonderful. If the minature equipment with the full range of proportional control available to us today, that we take for granted, had been available in those days, it would have probably have been a closely guarded military secret and would have cost thousands of dollars.
