Ah go it, for some reason I thought F4 was the one not supported, anyway my bad
Great to hear it's something that might happen eventually, this Femto is yet to be made available thus yet to see is it good or not.
By the looks of it, it's very promising and I would certainly love to have the best of both worlds, a decent nano sized fc and the best GCS/fw out there.
Thanks for pitching in on this, highly appreciated!
