In Re the original question, there is probably plenty of room in a Kadet fuselage. A further thought on the transmitter is that you will want to change the battery if you haven't already. Transmitter batteries are kind of out of sight, out of mind and it may take enough of a charge to work the controls but old batteries definitely have a shelf life. One upside to old radios is that you seldom have to wait for a frequency pin. I was one of the last hold outs on 72 mHz in my club and I switched over 5-6 years ago.
