So the last set of pictures it is DEFINITLY on wrong everyone agree ??
Yes,..prop is definately on backwards...and speaking of props,...look at this one,...while flying today, the high speed needle valve bracket broke, letting the needle valve assembly get sucked into the prop. Don't have a clue why it did that,..snapped in half.
Holy cow, I've never seen such debate over prop direction. Poor dragraces,,, Your prop is on the right way! according to this picture you took.
Forget ever thinking about letters and direction. Commonly your engine rotates counter clockwise looking at the cranshaft. So on a pusher craft/prop, your prop leading (thicker) edge hits the air first. Then your trailing blade edge should be closer to you (looking at the crankshaft) than the leading edge thereby forcing the air toward you. Make sense?
Crashpro, I have this happen 2x with a Tower .75 engine. That metal is stamped and weak and eventually will fail. Be advised on this to anyone flying this engine, you must reinforce this mounting, use a piece of carbon fiber or flat bar or something. There are voids in the stamped metal used and the vibration of the FG fuse will lead to the failure.
