Yeah, he had sent the engine in for the third time with problems and he ended up with that new ignition and no instructions...
I know, treat that prop like a loaded gun! I know that there was a hint of brain fart on my buddy's part here, but I am not sure I would have expected the engine to kick like that either! Fortunately for me, my only ignition switch is on my transmitter and I don't need to get anywhere near the prop to turn the plane on, and obviously never turn the plane on unless it is secure behind someone's feet or a restraint.
