Building Smart Drones with ESP8266 and Arduino

The drone moves in any direction

The drone moves in any direction even though the stick of the transmitter is cantered. To solve the problem, you must match the RC channel's 1 and 2 values to the PWM values displayed on the Mission Planner. If they are not the same, this error will happen. To match them, open your Mission Planner, connect it via telemetry, go to the Advanced Parameter List, and change HS1_TRIM and HS2_TRIM. With the roll and pitch stick cantered, the RC1 channel and RC2 channel should be the same as the values you wrote for the HS1_TRIM and HS2_TRIM parameters.

If the values are different, then calibrate your radio. The HS1 trim value must match the live stick cantered roll value, and the HS2 trim value must match the pitch ...
