"auto rescue" never allowing the helicopter go below a preset altitude is already possible

Oh shit! I'm really sorry I didn't think of that solution. I should have because I use Taranis which has telemetry and I was indeed aware that they also provide altimeters if you like, so yes I should have thought of this solution prior asking for a gps module. Yet, I like to know if this was possible from the very first moment that spirit came out, or -if not- when did it became available? I mean on which FW version? I guess that unit-wise it would only require a rescue function and since rescue was there from the very first moment, it was possible from day zero for someone who had a Tx with telemetry and altimeter, right? Thanks again!
