Hi,
thank you for your support!

In the wizard it mentions that it's important to use the correct pulse and frequency but does not say what will happen if it's set wrong. In the link you provided it mentions that setting it to high can over heat them. Is that all that can happen or are there other signs to look for?
When servo is running with higher frequency than designed by manufacturer, it can:
- Overheat
- Jitter randomly or put whatever deflection
- Not cause anything - servo will be not moving
The first two could damage the servos permanently, but it will rather take some time. Unfortunately it is individual for each servo. Usually when servos are really digital, they can handle also higher frequencies with no damage.
But always if you will set lower frequency, it can't damage the servos.
Regarding next question about frequency - manufacturers are rating their servos with frequency, but in some cases even if there is stated it can work on this frequency, it might get too hot with some kind of load.
For example if you will use Cyclic servo on the tail, then it can work, but usually not at the same frequency, because rudder servos must handle very fast movements that are there continously - it is doing something without a stopping and with a big jumps all the time.
While on the cyclic the servos are less active and movement is more smooth.
But for a short time it will of course work.
On the cyclic you can't set a bad Pulse - it is 1520us. So the reason for abnormal deflection could be only the frequency and that the servo is not "too digital".
But you will rather smell something if it is really damaged. Maybe the servos were connected just by one port off. E.g. instead of CH1 it was in AUX - but this will not damage servo too.
