Hi Looking a my planes, from the front, to back, mine turn counter clock wise for a tractor ( motor on front of the plane ) and as a pusher looking from the rear to forward, it turns counter clock wise, I use a tractor prop for a pusher, and have the numbers on the prop facing the front of the plane, as long as you have the motor turning in the right direction for the prop, I really dont think it matters, because you can reverse the rotation of the motor, by switching 2 of the 3 motor to ESC wires, hope that helps, take care, Chellie

Ps there are no Stupid Question, as long as a person learns from asking

There is such a thing as a "Stupid" question, it's the unasked one.

A brushless motor can rotate in either direction. The conventional direction for standard props is counter-clockwise looking at the front of the prop (the front curves out towards you and usually has any writing on it).

Default Hacker A30 12L

I bought a used Hacker A30 12L. The whole can rotates with the shaft. Is normal for an electric motor?

Yes. That's what's called an 'outrunner.' In an outrunner, the outer can spins. In an inrunner, the can stays still and the shaft (and other parts) rotate within it.

On any brushless motor (3 wires) you can change the direction of rotation by interchanging any two of the three wires. That way you can use any prop (the so called "tractor" or "pusher" version) and just set the motor to rotate in the proper direction to produce thrust in the desired direction by the way you connect the three wires. You want the face of the prop with the lettering on it to face forward; i.e. in the direction of the desired motion of the object.
