Then you just flash the board as usual, and.dont need to manually download the firmware from diatone. Soon you will be able to select the FURYF3OSD board from the dropdown (from betaflight 3.2…). THis is usualy straightforward within betaflight, but since the Diatone fury F3 OSD flight controller is a custom board, it is not in the dropdown list (for now). However, for whatever reason, you may want to update, or reflash the firmware. If you have purchased a shiny (and fast) crusader GT2 2017 kit, it ships with the latest betaflight 3.1.7 firmware (as of the time of writing this article).
