i agree with all these points. overcorrecting and disorientation/reverse controls are by far the most deadly. i've had many opportunities to practice getting out of the death spiral because the student overcontrols, gets disoriented and inputs the wrong aileron input to correct, exacerbating the situation. but my pet peeve is when students pulse the controls. instead of a smooth input, they do a series of jam and releases that make their planes convulse. anyway... to add to the list

Flying Too Far to See - i can't stand students that fly so far that i have a problem seeing. i've had to run after a plane before. literally tore off the trainer cord and ran after the plane (or where i thought it would be since i couldn't see it!!!)

Flying Too Close to the Pits - i can't stand it... can't can't can't! when people (experienced alike) fly dangerously close to the pits. i hate it when i'm flying and a plane comes within a few yards of me on a low pass. i really just want to reprimand them. i've gotten hit just a week ago AGAIN! an electric pylon racer lost it while flying nearly completely on the wrong side of the flight line (what an idiot!) it came full throttle smashed into one parked plane, scoring the tail before smashing into my leg. luckily, i wasn't bleeding or anything. they guy comes by, claims radio interference and scurries off. i told him not to fly behind the line and he shrugged and said "radio interference" no amount of profanities could suffice!

i don't care how poorly you fly, how many mistakes you make and how out-of-square you put your plane together... just keep away from PEOPLE! i'm really dreading the day that someone gets seriously injured at the field.
