Note
There are many integrated functions of flight control, and the components are very dense. During installation, please do not use tools (such as needle-nose pliers or sockets) to tighten the nuts, which may easily scratch the fly tower hardware and cause unnecessary losses. The correct method is to press the nut with your finger, 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 when installing and debugging the flight control, try not to test flight indoors, so as not to cause a safety accident. Before installing the propeller for the flight test, please check the motor steering and propeller direction again. Safety Tips: Please do not fly near the crowd. Our company will not be responsible for any loss caused by the crash of the aircraft.
Do not use non-original aluminum columns or nylon columns to avoid damaging the flight control hardware. The official standard is a custom-sized nylon column to fit the flying tower.
Before the aircraft is powered on, please check whether the installation between the fly towers is correct (pins or cables must be aligned and installed), and then check whether the positive and negative electrodes of the welding are correct and whether the motor screws are against the motor stator to avoid short circuit.
Check whether there is any solder that is thrown out on the electronic original of the flying tower, which may cause a short circuit. If the short circuit occurs during the installation of welding, the buyer is responsible for it.
