Your multicopter's maiden flight

Are you ready to get this thing in the air? Let's do this. You should have your laptop and guidance system interface cable (USB cable) with you. The batteries you use should also have a full and fresh charge on them (within 24 hours of flight, they should be charged). We'll be conducting several flights as a part of the maiden. The first one will be a battery calibration flight.

Battery calibration

When your multicopter spins up and takes off, that is called putting a load on your batteries. Even though your batteries are full, immediately your voltage will drop. In order for your guidance system to know when power is getting low, it needs to know what your load differential is. This is the difference between the resting voltage of your batteries and the load voltage. For that reason, either mount your camera to the multicopter's gimbal, or something that is of equivalent weight. (For your maiden flight … I advise you to use a weight.)
