where the head points to, the forward direction is still the direction of the head when it took off.
Propellers
The 4K/3D aircraft use 9450 propellers
，
the propellers feature black or silver-colored caps,
each representing a different direction of rotation.
1. Attaching the Propellers: Find the motors that have a hole, attach the propellers with a
black cap onto them and rotate them tightly counter-clockwise. Attach the propellers with the silver cap
onto the motors without a hole and rotate them tightly clockwise.
2. Detaching the Propellers: Please hold the motor on one hand, then rotate the propeller in the
unlock direction to loosen it.
* Make sure that the black and silver propellers are installed on the right motors; otherwise,
the aircraft cannot take off normally. Please manually tighten the propellers, and ensure you
tighten them firmly, otherwise an accident may happen. Since the blades are thin, be careful not to
hurt yourself with them.
* Please use the original UPAIR propellers, the propellers must correspond to the exact
aircraft model.
* Propellers are easily consumed, if necessary, please purchase an additional one.
* Maintain a safe distance once the motors and propellers start spinning in order to avoid any
injury.
* Ensure the propellers are in good shape and tightly attached before flight. Deformed or broken
propellers should be replaced.
