Tricopter servos

Hi,

I'm looking at building a Tricopter and I've been struggling to find any details on how people choose the servo they use for yaw. So...

What are the factors that people take into account when choosing the servo? Prop size, copter weight, etc?

And how do those factors affect the servo stats that we would ideally be looking for? torque/speed/servo weight/...

I'm looking for more generic "rules of thumb" answers than something specific for the setup I'm planning. However in case it helps my current plan is for a ~180mm MTM Tri swinging three bladed 5 inch props (early days in planning), with servo mounted on the Tri's main body (i.e. whole rear arm turns).

I've tried running through a few searches without luck, so if anyone has any pointers I'd appreciate it.

Thanks,
Nic
