Yes BevThat was a common set up in the fifties actually there was a lot of rudder only. That airplane is a replica of my first successful RC airplane and at first this time around I flew it on rudder only but had to many near fly aways so later added a servo and changed engines to a vintage OS that had a baffle throttle. Rudder also contolled altitude based upon how steeply and how long you held a turn.

At one time AMA pattern contests had classes based upon the number of control surfaces you were using.
