Arduplane with second pixhawk

Would like to setup a second pixhawk that would crash the plane (full down elevator) if for whatever reason the plane has deviated more than 100 m buffer from the geofence set on the main pixhawk.

 This is for additional safety and would also ensure t

 The setup delivers ~35 min with 16,000 6S lipo and 1.8 Kg useful payload.

 More scope for extended endurance beyond 40 minutes with la

 Especially with auto missions it is rather frustrating if the system goes out of range and then there is no telemetry for the rest of the flight

 My device, an arduini mini, works fine if I use signal pass-through to the axillary channel but it doesn't get triggered with CAM_TRIG_DIST.


I am using PIXHA
