Hi David,
Here is a complete parts list for a 2-axis G5 Based autopilot in an RV7, which includes the servo mounting hardware required to attach the servos to your specific airframe.
- Part Number 010-01946-00 GMC 507 $1160
- Part Number 011-01824-01 GMC 507 Connector Kit $50
- Part Number 010-01485-01 G5 Unit Experimental Aircraft $1495*
- Part Number 010-12493-11 G5 Installation Kit $111
- Part Number 010-01068-20 GSA 28 $885
- Part Number 010-01068-20 GSA 28 $885
- Part Number 011-02950-00 GSA 28 Servo Connector Kit $55
- Part Number 011-02950-00 GSA 28 Servo Connector Kit $55
- Part Number 011-02952-12 GSA 28 Servo Installation Kit, RV-7/8/10 Roll $105
- Part Number 011-02952-14 GSA 28 Servo Installation Kit, RV-6/7/9 Pitch $105
With this equipment your autopilot would be capable of flying the aircraft in the following modes:
- PIT - Holds an absolute pitch angle, as programmed through the flight director
- IAS - Holds the flight director commanded airspeed target
- VS - Holds the flight director commanded vertical speed target
- ALT mode - Holds the flight director commanded altitude target
- GPS track - Holds the aircraft on the flight director commanded GPS track
- ROL mode - Holds an absolute bank angle, as programmed through the flight director
- LVL mode commands the aircraft to straight and level flight with a single button push.
If you have existing DC Trim motors installed that drive your trim tabs, you can wire them through the GSA 28 servo(s) and the system will automatically drive the trim tabs while the autopilot is engaged to ensure the aircraft is in trim when you disconnect the autopilot. There is no additional equipment required for this, it just requires some wiring changes.
Here are some components you can add in the future to add more capability to the system:
- GMU 11 Magnetometer - Enables HDG Mode
- GPS Navigator - Example Aera 660, which Enables NAV and VNAV mode to follow external navigation guidance. A GTN 650 Xi would allow the autopilot to additionally fly a fully coupled approach procedure using the APR button, as well as provide the ability to follow SmartGlide emergency guidance.
- GAD 13 - Provides Outside Air Temperature data to the G5 which is used to calculate winds aloft and True Airspeed
