You can launch payloads and use RCM, just download the software that it says and then you can go to SDSetup page. It would be better if you have at least 64 GB sd card or more. You can't avoid groundingOk so it sounds like choosing fusee-gelee is the way I should be going forward. Now Im debating if Im on the stage where Im supposed to check if my Switch has the capacity to use RCM to launch payloads, or if I can go directly to the step labeled "SD Card Setup Fusee-gelee"
Assuming if its the former, then it seems I need to do that jury rigging with the ground pin 10. Dont know if there is a way for me to avoid that or not. Or maybe Im misunderstanding the step Im on. Sorry for the continued questions
