Switched a plane from right to a left hand prop without switching the wiring....

Minimal damage to all except my ego! 

This makes me laugh a little that even the greatest of us can have brain f***s once in awhile.  Remember the Mouse Racers that went back wards into the circle when the pit man was too anxious to release the plane.  Wonder we didn't get our fingers wacked on those starts.

Even though it costs some rpm, the local Mousers all use the ratchet type spring starters to guarantee correct direction starts.
