Replacing propellers
The propellers on a quadcopter have two rotational profiles, counterclockwise and clockwise. Getting these
right is important for proper flight. Take note, or use the picture below, to find out which way the leading
edge of the propeller should turn. The kit comes with two sets of propellers.
1. Use a small piler to use as a lever to push the propeller off the motor shaft
2. Separate the new propellers into two batches, with the letters facing up; counter-clockwise (marked
B1 or B2) and clockwise (marked A1 or A2) type
3. Use the picture above to install the propellers on the motor shafts. An easy way to remember the
rotation is that the leading-edge/tip of the two front propellers always face each other and likewise
on the tip of the two rear propellers.
