Autopilot Configuration Question

[nealdraper]

Chuck,

I understand from a previous owner the autopilot system was working, so I assume the correct size hydraulic pump had been installed.

It appears I would need an EV-200 Power Pilot, an EV-1 sensor core and connection to an eS series chart plotter acting as the course computer.

Would I need to utilize a P70R Auto Pilot control Head as part of this system, or as an option, to control course changes?

Thanks for your help. The information you provide will make it easy to deal with the electronics retailer / installer as I will fully understand what it will require to upgrade my autopilot system.
