Is it possible to use the Reserve Video-Downlink Port (USB) for a secondary monitor? I'd love to use my cinemizer goggles while still having the app run through my phone.

Hi there, thank you for reaching out. Regarding with that it's not possible to use 2 ports at a time but what I can see possible is your device must be capable of having an output display for example device that has a HDMI out capability and also mirroring the screen of your device going to other monitor.

Unfortunately not. I used to do this with my spark. It connected to the RC via wifi, leaving the usb port of my phone open for a usb to hdmi converter.
