Servo not working


Ive upgraded the Arduino (it worked the 3rd time) - but when I connect to and try using Q A Z to control the servo nothing happens (I havnt configured the ESCs yet - but this shouldnt matter?).

I see the value goes up on the servo from 1500 to 1800 so something must happen.servo image as you can see from the reading in the cockpit picture attached.

Any idea why? The cable is connected to D11


solution is probably: "To get the servo to work, a ESC has to be connected, and powered on. the servo gets its power from the ESC's"

as described in this post:

so ill configure the ESCs and try again.
