I’m answering here, so we won’t derail the other topic. I think you should first do a few flights with it in 2D. Sometimes BATC just won’t understand a simple line and keeps asking back to repeat, so I was taking some chances doing that flight. Once you get the hang of it I think it’s safe to jump back to VR, but still, be aware that you might need the BATC window no matter what.
I hope the VR window for BATC is not far off. That would make it a lot easier.
