ET OSD Pro with FMA Co-Pilot
I have built my own FPV plane, 1.8m wingspan. Its got heaps of up front cargo space so have fitted the eLogger V4, OSD Pro, 5.8Ghz Video gear, TM1000, the Baro Altimeter, GPS, and the Guardian for stablisation.
I have now flown this in full FPV mode beyond visual range with a 5.8Ghz Video TX and RTH has worked nicely.
Below is my working wiring diagram, the main interest is the Aileron & Elevator going to the OSD, and the Rudder going direct to the servo from the RX. I was using the v3 Logger that needed the addition feed of 5V, unlike the V4.
I have the Baro Altimeter, daisy chained off the Guardian, as the GPS altitude is not reliable for me. It often stays on zero for the first half minute in flight, despite having > 7 sats locked up. The baro gives a much more responsive reading.
