Analog servo interface for Century, ARC Cessna and Stec Legacy servos.

Interface box that connects the SuperECO Autopilot Instrument to Legacy analog autopilot servos.

THIS PRODUCT IS AVAILABLE FOR EXPERIMENTAL AIRCRAFT ONLY. 

If you have a Century, Cessna ARC, Stec or any other legacy autopilot that uses servos that work with an analog voltage and a clutch you will be able to take advantage of this interface.  

The old electronics that drive these servos is obsolete, unserviceable or too expensive to update or repair.  Your servos are very good quality and they will last for ever. You can now replace these electronics with a modern SuperECO using this interface box.

The interface box will connect to the SuperECO via a serial RS232 port and will have output for up to two servos.  Each output consists of one pair of wires to drive the servo motor and another pair of wires to engage the servo clutch.  

If you need to connect a third servo for a Yaw damper, two interface boxes are required.

Purchase the optional custom made harness (p/n 3900194A) and we will prepare a turn key connection for a direct replacement of your legacy autopilot system.  If not, you can make your own harness and directly wire the interface box to your servos, purchase the standard wiring harness (p/n 3900195A)
