Changing receiver pins

[sph311]

Hi everyone,
I plan on using a arduino mini pro for a tricopter build. I need to control another servo with the arduino, so I was wondering if the pins that connect the receiver to the arduino need to be PWM. So would I be able to switch the YAW pin to D8 instead of D6 so I could have a spare PWM pin?

Thanks for any help

arduino mini pro is 328p?
In general, do not move around pin assignments unless you know your way around.
328p with MWii would allow for more than 3motors+1servo outputs, I think.
Try and find how additional gimbal servos are supported.
