I had a midwest cap 232 with a quadra 40xl. The throttle stuck a little over half open. The engine was running a little fast for normal flight so I started spiraling up and when I was high enough I would flat spin it back down careful not to get to low in case the engine would die and then just start over again. I am considering a self destruct mechanism so that I can destroy the plane before it gets away though (just kidding) Jon
