Hi Geoff
I just posted this on your other topic re hunting. I think it is important enough to repeat here as I think you are talking about the same servos.
URGENT. URGENT
STOP IMMEDIATELY
I just had a look at several data sheets for a MG995 Servo
They all say operating voltage between 4.8V and 7.2V.
There is little wonder your servo seems to traverse as you say “Violently”
This would not help with the “hunting” either.
If you haven’t destroyed the electronics get the supply to within specified range and try again.
I would get 3 new servos anyway as any damage due to over voltage could be cumulative and fail down stream.
Cheers Bob
