usage notice
There are many integrated functions of the flight control, and the components are very dense. When installing, please do not use tools (such as needle-nosed pliers or sleeves) to screw the nut, which is easy to scratch the tower hardware and cause unnecessary loss. The correct way is to tighten the nut with your fingers and the screwdriver can quickly tighten the screw from the bottom. (Remember not to be too tight, so as not to damage the PCB)
Do not install the propeller during installation and commissioning. Before installing the propeller, please check the direction of the motor steering and propeller again. Do not use non-original aluminum or nylon columns to avoid damage to the flight control hardware. The official standard is a custom-sized nylon column for the fly tower.
Before the power is turned on, please check whether the installation between the towers is correct (it must be arranged with the pins or cables aligned), check whether the positive and negative poles of the welding are correct, and check whether the motor screws are against the motor stator to avoid short circuit. Checking the electronic components of the tower for soldering out may result in a short circuit. If the short circuit occurs in the installation soldering, the buyer is solely responsible.
