Jesse Haven't tried that myself. But they are the same hardware

Jesse No it must be hand-washed, just wipe it with some cleaning cloth such as Alcohol.

Jesse This is an analog receiver on the goggles, you need an analog transmitter. It's not HD.

Jesse Connect the inverted SPort on RXSR to a vacant Tx port (T6 for example). Setup serial half duplex on betaflight, turn on FPort. Note you have to solder the TX+RX wire to inverted SPort on RXSR. SBus connection could still remain, but not used if you use FPort

Jesse In total 3, one is for the VTX, one for receiver telemetry, one more free for ESC telemetry

Jesse Depends on the mounting size on that frame. If it's 19x19mm you can just use a nano to micro mounting transfer

Jesse It’s fast because it’s very lightweight with 1408 motors at 4000KV. It will not explode on a 4S, unless if you’re going full throttle for the whole flight. Motors could draw 30A but the ESC could take momentary burst.

Jesse A bit too small for a 15-inch, don’t hope for too much space. 13-inch will do
