Hey, so I have a Happymodel EP2 RX, and the connection diagram labels two of the pins, tx and rx, now on the schematic for my Mamba FC, it labels them ch1 and ch2, connecting to a crossfire nano. Which is which?

Awesome, thanks! SO. I now have the ESC all soldered up, the fc is soldered to the rx, and following Oscar Liang's guide, I'm to test the motors. However he gives no information on betaflight, fc firmware, etc. Basically all the guide says is plug in the drone, and in betaflight spin up each of the motors... I assume I have to a) install betaflight on a laptop or something b) plug in the fc to the computer c) flash firmware to fc, and d) probably some other stuff? And I don't know how to do any of that...PLEASE HELP
