Currently I am working on my first project related to RC models. My vehicle is a V-tail plane, as shown in the following image.here. My throttle output pin is therefore the main pwm pin number 3. The next step for me was to calibrate the ESC. I am using a Red Brick 70 A esc. Both the ‘all-at-once’ calibration and ’ Manual ESC-by-ESC Calibration’ failed for me. However, after the manual calibration, the motor began spinning when my throttle stick was at its maximimum position. Then, using trial and error I managed to get everything to work well after using the alternate esc calibration method as written here.
The RC channel throttle input to the pixhawk had a PWM approximately in the suggested range of 1100 to 1900. However the servo output at the main pwm out number 3 which I used for the ESC had the range as shown in the following image.
