Basic understanding of propellers on a
Lesson: If you find your multi-copter flipping on take-off or
just don't seem to take off, the first thing to check is your propellers or
motors. If your propellers are spinning on the wrong direction, the thrust might
just be pushing your copter down instead of lifting it up. If you have the
propellers in the same orientation next to each other, it may just topple your
copter. Propeller are usually marked with the spin direction and they
should match the diagram illustrated below.
Setting correct spin directions
The direction the motors spin (clockwise or counterclockwise) is determined by
the connection to the ESCs. As you apply a small amount of throttle to the motors, check and
see what direction they are spinning in, stick a masking tape to visually help.
Motors should spin as indicated by the diagrams below according to type.
Check the diagram below to see what direction each motor should spin and verify
that the motor does spin in the specific direction.
Take note of which motors needs to be reversed and disconnect the
battery from your copter.
To reverse the spin direction of a motor, switch two of the three cables
connecting the motor to the ESC by disconnecting two of the bullet connectors,
switching the wires, and reconnecting as shown below.
While it is good to charge and store your LiPo batteries in fireproof bags, we
actually have our little DM tip;
add another base layer of silicone bake ware. Yes, silicon have been tested
and proven to be high-heat resistant up to 500°F or 260°C. So, visit your kitchen,
you may just have one handy.
Inspect your LiPo carefully after a crash, a punctured LiPo will
begin to bubble at high temperature before releasing a thick smoke and burst
