I just switched from a Spektrum DX6i to a Taranis X9D+ with Aerofly RC7 and found that the same JR-compatible cable works fine (USB dongle plus mono connector to trainer port on Taranis), *but* you need to make sure that the Taranis trainer port is sending an output signal: on the Taranis, create a model to use with Aerofly, and then in the MODEL SETUP Screen: set “Trainer Port Mode” to Slave/Jack. If your mac has a dedicated Mic input (not a dual Headset/Mic), you can use the iSpectrum oscilloscope app to watch the output and see PPM pulses.
Dear errorwolfi
I have the same issue as it seems. I cannot connect my Taranis to Aerofly 7 on a rather new iMac.
Assuming your connection kit does work, how did you connect the Taranis to you Mac?
Did you use your USB cable? If yes, then did you connect the Rx in Boot-Mode? Can you help me understand what do did?Many thanks, Georg
