pusher props
I finally received my combat models fa18 hornet. It calls for a pusher prop. How does the pusher prop work. I bought one and it looks just like a regualr prop. Does the engine run the opposite direction?clockwise? does the prop go on backwards?
I just can't understand how it works. I put it on one of my regualr planes and it worked just like a reguar prop. The only thing that looks different is it looks like it has more of a pitch.
Help Please!!!

Basic difference is that the blades (hence, "airfoil") are 180 degrees from the standard tractor prop.
To install the pusher prop correctly the writing or marks (convex or curved side) on the prop MUST face the engine (front of the aircraft).
My pusher experience has been OK but I find that the selection of pusher props is not the greatest - especially when you get into the .60 size and above.

pusher props
Hi, I have the CBM F-16N pusher jet and have 40 flights on it. I have to disagree with Dan. Pusher blades are not 180 degrees from the standard tractor prop. Pusher prop blades are a mirror image of tractor prop blades. In other words, if you place a tractor prop on a mirror, the reflected image of the prop is what a pusher prop will look like. Right now I am holding a tractor and a pusher APC 10X8 props together and what I see is that the blades are mirror images of each other.
I wonder if you actually bought a pusher prop. If you put one on a tractor plane and it didn't give you reverse thrust, I doubt that you have a pusher prop. The only way to get tractor thrust from a pusher prop is to run the engine backwards (and vice versa). If you have even a hint of dyslexia, your brow will be furrowed right about now. Pusher props confuse a lot of people and if you bought it at your local hobby store someone may have put a tractor prop in the pusher prop bin. I once ordered pusher props from Tower and they sent me tractor props for probably the same reason. If your prop is an APC it should have a P designation right after the pitch number on the prop like this "10X8P". Zingers have the same. Graupner pusher props say "pusher" right on them.
One solution to the lack of pusher prop sellection is to get an engine that can run in reverse (not all can do this, it is an issue of intake/exhaust timing). Then you can use tractor props mounted backwards. Whatever prop and rotaion you use make sure that the prop is mounted on the engine so that the rounded leading edge of the prop is ahead of the sharp trailing edge with respect to the direction of flight. Good luck with your F-18. If it flys anything like the F-16N, your going to love it.

PUSHER PROPS
CRAIG IS RIGHT ...CHECK FOR THE "P" FOLLOWING THE PROP SIZE & PITCH # JUST REMEMBER KEEP YOU PUSHER PROPS AWAY FROM YOUR REGULAR PROPS IN CASE YOU MOUNT A PUSHER ON YOUR PLANE WITH A ENGINE IN FRONT. THAT WOULD BE A SIGHT A AND AN NEW EXPIRIENCE.
CRAIG...HOW DO YOU LIKE YOUR CBM F-16N??? SEND ME A PM ABOUT YOURS AND WHAT YOU THINK OF IT.MINES STILL IN KIT FORM AND I HAVEN'T WRECKED IT YET!!!

pusher props
guys, i really appreciate all of your comments. they've all been helpful. I ordered mine from tower and there is no P behind the apc logo. So I guess I'll have to reorder. Thanks again for all your help.
