Thanks for your patience. Turns out it was really simple when you know what to look for.
For my tests I just use the same servo tilt unit. The one that comes standard with BR2.
I found that all 3 AUX servo outputs are very jerky and quick compared to MNT1 (where tilt is usually connected)
Is there a way to slow down/make the tilt motion as smooth with the Aux outputs?
Secondly, the range of the tilt is very limited. Can I use the full span of the servo motor?
QGC says the limits are 800 to 2200 why is that?
Lastly when fully tilted down, there is a noticeable “hum” coming from the motor until I jerk it up a bit. This hum is also present if connected to MNT1 output but MNT1 is less noisy.
I am wondering why this hum is present, how much current it wastes and if it is damaging to the servo.
