I wont even attach the glow driver from the front. I heard of a guy who put his glow driver on a never ran Saito and it started on it's own. I guess thats possible if its on the compression stroke. Being a creature of habit I have a routine. I fill the tank and prime the engine. Then I turn the prop way back to just after compression stroke. (I only use 4 strokes). Then Ill get behind prop before I turn on the TX and RX and hook up the glow driver. 99% of the time I'm flying with a bud and Ill have him hold the plane from behind so I don't have to reach over the props arch to hold the plane while applying the starter. The inside of the forearm has some pretty big arterys and I want all the blood I got!
Never remove the glow igniter from the front of the plane and never adjust the needle from the front of the plane. And be extra carefull with big 4 strokes. Sometimes they start up running backwards and Ive had a 15" prop, spinner and all back off and fly 30'.
That dude in the video is crazy. He had his face right down there in front of the prop more than once wearing what is probably glass sunglasses. If that broken prop would of hit him in the eye at that range, it could of drove glass and prop into his brain killing him.
