well for obvious reasons u dont use your hand!!! i found out (and it wasnt even a nitro)

(i had a "mishap" before with a peed 480 motor and a 9 inch prop - was checking something on the plane and holding the tx and plane at the same time, one of them slipt, throttle to full, and to catch both with out any damage i kinda had to face teh prop [&o] with my finger tip = bruse/cut in one - funny thing is i didnt notice it cut me until it leaked blood on my tx; thus ended flying for that day haha)

thanks guys for answering this question! all input is appreciated[8D]
