I'm a new user and I didn't succed in using ma SkyLark AAT IV.
I have no OSD (for the moment), so I do the wiring only with GPS, AAT convert module and return with the Audio of the Video TX. Calibration is Ok, north is OK but when I move my wings, the tracker didn't follow it. the audio LED on the AAT is still fixed (no blinking).

Do you have a idea ?
