I doubt ypou will burn that out.

Stick a prop on and check the air goes backwards
Thats it soldered up right then. All motors go backwards, a few timed
ones just do it rather less efficiently. You won't have a timed motor there.

Then the only other thing is to make sure the prop is right way round,
or it will be less efficient. Make sure the concave side of the blade is
towards the back of the plane.

1. You can't burn most motors out by running them backwards.
2. The + terminal on many cheap can motors, like the POT 03, is marked
with a red dot.
3. In a typical single-gear-reduction system, you would connect the -
(negative/black) wire to the terminal by the dot to make the motor run
backwards for a typical tractor prop.
4. "Normal" propellers rotate counter/anti clockwise when viewed from
the front of the plane, facing the rear.
5. The propeller will blow air in the same direction even if you flip
it over. The only way to change which way the prop blows air is to
spin it backwards.
6. Direction of rotation is irrelevant as long as the propeller blows
the air in the correct direction.
7. There is a right way and a wrong way to install a prop. Flipping
the prop over won't change the direction it blows air, but it will
make it much less efficient.

if you follow that link there is a picture of the motor assembly click on
that to get a large image that shows which terminal is + and which is -
relative to the circuit board on the back of the motor.

The motor uses a

If it's configured for reverse rotation, it will run more efficiently
backwards, that is, the shaft should turn clockwise with it pointing at you.
These motors are used either in a direct-drive pusher configuration, like on
a Zagi, or with a gearbox.  Your motor will still run in the normal
direction, but it run better backwards.
