David,
That is good to know. Sorry if I got your hopes up. We had heard from other iFly / SkyRadar customers that this was possible, but the model was unclear. We will make sure we advise properly going forward.
I've reached out to Alexey for clarification on this and for a demo of their new DX model to be coded up for the AHRS, but we have not received anything yet. Thanks for the info about the D2 only upgrade.
