* **Check the remote control**. Using `rc` command, check the control values reflect your sticks movement. All the controls should change between -1 and 1, and throttle between 0 and 1.
* If using SBUS receiver, **calibrate the RC**. Type `cr` command in Serial Monitor and follow the instructions.
* **If using SBUS receiver**:
* **Define the used GPIO pin** in `RC_RX_PIN` parameter.
* **Calibrate the RC** using `cr` command in the console.
* **Check the IMU output using QGroundControl**. Connect to the drone using QGroundControl on your computer. Go to the *Analyze* tab, *MAVLINK Inspector*. Plot the data from the `SCALED_IMU` message. The gyroscope and accelerometer data should change according to the drone movement.

### Control with a remote control
Before using remote SBUS-connected remote control, you need to calibrate it:
Before using SBUS-connected remote control you need to enable SBUS and calibrate it:
1. Access the console using QGroundControl (recommended) or Serial Monitor.
2. Type `cr` command and follow the instructions.
3. Use the remote control to fly the drone!
1. Connect to the drone using QGroundControl.
2. In parameters, set the `RC_RX_PIN` parameter to the GPIO pin number where the SBUS signal is connected, for example: 4. Negative value disables SBUS.
3. Reboot the drone to apply changes.
4. Open the console, type `cr` command and follow the instructions to calibrate the remote control.
5. Use the remote control to fly the drone!
