I was flying alone at my local field and was holding the plane while taching it to get the lowspeed needle set. I accidentally bumped the throttle to almost full and the plane just rocketed. I grabbed hold of one wing and it started spinning me in circles. Imagine someone holding an 80" ws plane by one side of the wing, going in circle control-line style, while trying to pick up the transmitter every full rotation. It is funny, but I'm lucky the prop didn't rip my achilles tendon apart or mince my family jewels.
