Want a real challenge? Most trainers can be flown with just the throttle and rudder, never touching the elevator or ailerons. Trim the airplane to fly level at half throttle and then go for it.
I like to do one better - take the plane up, intentionally dead stick and trim it out for a nice glide.
After landing, restart it and take-off. Set the throttle for a slight climb and don't touch it using only the rudder for control. Fly it until the fuel runs out and dead stick it back to the runway using only the rudder (not touching the elevator).
While flying under power, try gaining momentum and do a loop or rudder roll. Lots of fun to be had flying a trainer as a single channel. And for the newer flyers out there, they used to fly single channel aerobatics in competition.
