MultiWii 2.40 QuadCopter Experiment Platform Mk-1

Not shown in the video (you can easily find it elsewhere):

1. Calibration of Acc/Gyro sensors (IMU 6050)
2. Calibration of compass sensor (HM 5883L)
3. Binding of TX/RX After calibration, the platform was put onto my notebook, which was not flat, so the roll and pitch did not show ideal positions.
