Pre-flight Check:
In many cases, the cause of a Quadcopter crash is not checked before takeoff. For the sake
of safety, we suggest that you check before every flight.The steps are as follows：
1.Turn on the transmitter and select the correct mode. Please confirm that the arming switch
on the transmitter is in the “disarmed”position and throttle is all the way down;
2.Please perform a physical inspection of the Quadcopter for damage. If there is damage,
please repair first;
3.Please comfirm the propeller is in the right direction and the propeller nut is locked,
otherwise there is a risk of crash;
4.Check LiPo battery voltage. A fully-charged LiPo should be about 4.2 volts per cell, or
about 12.6 volts for a 3S, or 16.8 volts for a 4S;
5.Please comfirm the battery is securely attached to the aircraft by the strap. And secure the
balance lead so that it can’t be struck by the props;
6.Please Scan the flight area for any safety issues that might be present, such as people or
animals;
7.Verify that you have clean, strong video in your FPV goggles or screen. If you see
interference or you see another pilot’s feed, resolve this issue before flying;
8.Arm the quadcopter. Listen for the props hitting anything like an antenna or the battery
wire;
9.At this stage, take off and enjoy flying.
Note: if you choose to fly close to water, please pay attention to the flight safety. It is difficult
to salvage the Quadcopter when it falls into the water, and the water in the Quadcopter is
not covered by the warranty.
