Hi,
I have Favourite Sky III 30AX4 4 in 1 ESC. I'm calibrating the ESC like this;
1. I put radio on, I set full throttle
2. I power up Pixhawk and wait for musical startup tone of Pixhawk and then disconnect the battery
3. I reconnect battery and I hear a low sound which after I press the safety button
4. Pixhawk goes to ESC caibration mode
5. I reduce the throttle to minimum and I hear as the escs accepts the calibration and saves the values to the ESC
6. Then I disconnect the battery from Pixhawk
After one minute I power up the Pixhawk but the ESC sound is similar as the throttle would be up. I have understood that Pixhawk shouldn't give any PWM outputs before arming. Why Is Pixhawk giving the ESCs indication of full throttle????
