When the red bars for roll, pitch, throttle, yaw, and radio 5 (and optionally radio 6, 7 and 8) are set at the minimum and maximum positions, select Click when Done. Mission Planner will show a summary of the calibration data. Normal values are around 1100 for minimums and 1900 for maximums. If the bars go in the opposite direction of the direction you’re moving the sticks, that means that the channel is reversed on your RC transmitter side. Use your RC transmitter’s channel-reverse function to reverse it at the transmitter sid. (see your RC gear’s manual for that, if you’re not familiar with the process)
