Not gonna lie, but for me, it's gonna be mostly the hobby relaxed ones like
r/diydrones
r/fpv
r/radiocontrol
because I don't think many of them are willing to switch to another platform. The tech subs about 3d printing and stuff already exist here and simply need to grow.
I'm hoping for an fpv community on lemmy, I've been flying and crashing my apex for a few months now, and it's about time for the largest repair yet. I'd love to share the process on here somewhere.
