i made a pun jet with the motor salvaged from a puller.
so obviously forgot to change motor direction.
somehow my mind went blank .. thought "ey why not change the direction from my transmitter!!"
so i did ... and by doing so i actually changed my throttle from 0 to 100% !!!!!!!!!
and then the carnage started .. as the pun jet was laying on my table with the motor facing my arm !!!
