Some progress
G'Day Paul,
I've made some progress. The supplied Y lead has the wrong plug on the HKPilot end. Once this is swaped and the Tx and RX of the Osd are connected to the TX and RX pins of the HKPilot (that is tx to tx and RX to RX) the Osd came to life. To be fair the HK instructions do include this info, but in a comment about the GPS port! Still no joy with the data radios. The elevon mix setup for a wing has me stumped as well at the moment. I'll keep you posted, but I'd love to hear if anyone else has a working setup.
Regards
Mark
