Propeller Model: 1045 Propeller (The "10" in 1045 indicates a blade length of 10 inches. The last two digits "45", indicate the pitch, which is 4.5 inches. Pitch refers to the distance that the propeller can move forward in one week of rotation.)

Distinguish between "CW" and "CCW" propellers:
· "CCW" propellers are marked with the letter "L" on the blade and rotate counterclockwise to pivot the airflow when viewed from the front of the "CCW" propeller blade.
· "CW" propellers are marked with the letter "R" on the blade, and the airflow is pivoted in a clockwise rotation when viewed from the front of the "CW" propeller blade.

Principle of "CCW" and "CW" propeller application on quadcopter：
The manufacturer's quadcopter is installed with 4 propellers, if they are all rotated counterclockwise, all 4 propellers will generate a counterclockwise spin torque, making the carrier spin to the right. So in order to counteract this spin, the quadcopter uses 2 CCW and 2 CW propellers (2 clockwise and 2 counterclockwise propellers) arranged in a circular pattern, with one pair of propellers twisting to the left and one pair of propellers twisting to the right to counteract the spin torsion of the propellers and equalise them.
