Hi @Matt_D,

You can try setting the [`SERVOn_TRIM`](https://ardupilot.org/sub/docs/parameters.html#servo1-trim-trim-pwm) parameters for your motor pins to be `1100`, with [`MOT_PWM_TYPE`](https://ardupilot.org/sub/docs/parameters-Sub-stable-V4.5.3.html#mot-pwm-type-output-pwm-type) set to `PWMAngle (9)`.

That said, @tony-white is correct that ArduSub expects to be using reversible motors, so I’m unsure whether that will actually work properly / as expected, and am similarly curious what your application is.
