One way to recover from a spin is to throttle down the engine
then turn the rudder in the opposite direction of the spin.
Eventually, your aircraft should level out, provided you have
enough airspace to execute the maneuver. At this point, you 
should throttle up the engine, remain in level flight for 
several seconds to boost your airspeed, then seek out your 
next target. Of course, you can always recover from a spin 
by cheating--just press Ctrl-S.
