When you install the prop is the sharp side the leading edge. for instance the airscrew prop do you install with the logo forward or the sticker?. Boy am I green

the molded information (brand, size, etc.) should be away from the engine--the nut should tighten up agains it. I'm assuming you're talking about a traditional front mounted engine, and not a rear-engine "pusher." The prop will turn counter-clockwise when looking at it from the front. While turning that direction, it should blow air back, toward the aircraft. The leading edge will be the fat edge--just like a wing's airfoil--and will taper toward the trailing edge.

the master airscrew or what ever the logo is goes on the outside.

thanks guys

There's an "outside"? Outside what?

"Logo" FORWARD.....

Remove the sticker and balance the prop. On Master Airscrew, it's a good idea to lightly sand the leading and trailing edges, or they'll be calling you two fingers.

or better yet, just look at the airfoil and decide yourself which way is forward. some props might have a sticker/logo on the back.

Yeah, my prop ends got sanded down... Damn prop strikes...
