I have a turnigy 9x And just bought a waterproof servo it says it has to run 333hz to get 270° instead of 180 where do I set this any ideas ?
It is running at 1520us at 333hz.
To get it to travel the full 270° you may have to use a setting called 'Extended endpoints' in your transmitter, but I cannot recall if the 9X firmware has that option.
