UPDATE ON THE TWIN PUSHER SUPER ENFORCER
The Custom Mufflers are finally and the rt motor counter clock crank is completed and tested
Stay tuned for the compled plane, I need to do the final prep for paint then assembly

left motor is a standard motor with a pusher prop, the right motor has a counter rotating crank in it I built, and uses a standard prop turned around, with these older motors you can remove the 4 crank hub bolts and rotate the assembly to the left now you have a counter rotating motor, or pay a machinist to make you a counter rotating crank, I just happen to have a full machine and wood shop so
I machine and build all my own stuff

the prop is on wrong on the left engine, the marking on the hup and prop are to face forward.
I once saw a guy with an Enforcer with the pusher prop installed wrong, labe facing to the rear. It had some thrust to taxi but never got off the ground until the prop was turned around.

APC is the best props to use best thrust and no confusion on which way to install them. The blunt or leading edge should face the edge to which the prop turns, on some other props you need to look at the pitch , its always best to do a bench static thrust test before going to the field., saves you from crashes

That may be true! The motor orientation makes perfect sense. But in the picture we're looking at the rear of the airplane, and while the direction (CW or CCW) of the pitch on each prop looks correct for the engine, it looks like we see the front of the prop not the rear. In other words looks like we see the upper surface of the airfoil on each prop - where the markings are - instead of the lower surface. Maybe it is a trick of the lighting, but it looks so convincing in the photo that it seems to be fooling everyone.
You must get pretty good elevon authority even at low speeds?

Dude, if that's the back of your plane, your props are on backwards. You can either listen to everyone else here, or please take video of the crash. Lol
Seriously though, the numbers on the prop always face the direction of flight, no matter tractor or pusher. You can choose to believe it or not.

Here is a example , you people out there who seem to think I am wrong, I suggest you get some experience with pushers, or do a bench test your self, the way I have the props set up, I have used this method for over 30 years with no problems, I am not some dumb ass flyer who puts a plane together without checking everything several times to make sure it is correct before flying, I see people every day who build and fly without checking the plane. then crash AS far as the numbers on the prop facing the direction of flight is also incorrect statement for APC props I called APC many years ago to clear up that matter. If it was a wood ZINGER prop then you would be correct about the numbers facing toward flight direction
Here is a example. if you take a standard rotation APC prop on the front of a plane the numbers facing forward, if you are looking at the prop it turns counter clockwise (left) and pulls the plane, if you were to turn the prop around with the numbers facing the rear and and turn the motor in a clockwise rotation (right) is now becomes a pusher prop

Sigh......where to start?
I'd sad to think you've been doing it wrong for 30 years. Please watch this video and you hopefully understand that you have the face of the prop facing the wrong way. Note the part where they talk about the numbers & letters facing forward, and about the spooned part of the prop facing aft.

Thank you for sending the video, it is correct for electric props. I just got off the phone with ROBERT at APC to clear all you people's confusion, as I stated I am no dumb **** and I know what I am doing, Robert confirmed I am correct and told me how to explain the correct prop installation for all you un experienced people, on APC props, the leading edge will have the numbers on that edge, not in all cases do the numbers face the front, . most all the electric props are made so the numbers face foward, with gas APC props, like mine the numbers DO NOT FACE FORWARD UNLESS its a standard direction gas prop because the numbers are on the leading edge. , in my case the pusher prop requires the numbers to face rear,( numbers on leading edge) and on my right motor its a counter rotating motor with a standard prop turned around, so in that case the numbers do face forward. I HOPE THIS CLEARS UP THE NON BELIEVERS, IF YO STILL DO NOT BELIEVE ME CALL ROBERT IN IN TECH SUPPORT AT APC YOUR SELF, AND HE WILL SET YOU STRAIGHT
APC'S NUMBER IS 530 661 0366 GOOD LUCK PEOPLE

Again, maybe it is a trick of the lighting. Nobody says you're a dumbass, but this forum is not populated by dummies either - experienced pylon racers, speed fliers, gonzo sport fliers, you name it. Everyone here that has looked at the photo sees the same thing.You could prove everyone wrong real quick with a close up of the two engines with the props in focus.
"left motor is a standard motor with a pusher prop, the right motor has a counter rotating crank in it I built"
In the picture above, the motor on the left looks like it has a tractor prop, and the right motor looks like a pusher prop.
Moving along..

Jockey,
I'm not sure what you told Robert, (who is not a tech btw, he runs APC actually) but you must not of been clear. I happen to know Robert, so I emailed him your picture. Below is what he had to say:
Hi Red,
Those props look backwards to me.
The leading edge of the prop should always be towards the direction of flight and towards the direction of rotation.
See you next week!
Robert

Hi Robert,
Sorry to bug you with such a trivial question, but are the props in the attached pics installed correctly for a pusher configuration? Not really important, just an internet discussion.
Cheers

It's unfortunate that you won't at least consider that you are incorrect. It makes no difference if the prop is for an electric plane or not, the answer is till the same. Notice what he says about direction of flight AND the direction of rotation? The cup of the prop faces aft, and the airfoiled side faces forward. Period. The prop orientation in your pic is simply incorrect.

Indeed.
If the left engine is standard rotation, and the right one is reverse rotation, then the props should be exchanged left to right...and both should be turned over front to rear.
As they are installed now, and the engine rotation is like you stated, the props are installed correctly for a plane that flies backwards. A twin-engined, backwards flying Enforcer, now THAT would be a first! ;-)

Folks looking closer at the photo of the motors on the plane I will admit I have them on wrong, I rushly put them on to just snap a photo attached photo is the correct way I was wrong in original photo only, sorry for all the confusion
this is the correct way they go I had them on correctly when I did the bench test

Here's a pusher.. looking at the front of the airplane with an invisible CCW engine.. numbers on the front as usual but the hub is reversed.
