It will fly just fine. If you do not need any of the benefits or new features introduced in newer FWs, do not updateOne more question... If I get this new unit, and hook it up to the internet, it will likely check for new updates... Will it still fly if I don't perform them? With my mavic 2 pro, I have older firmware, and it complains every time I fire it up, but it still flies fine... Just dont want to brick this second one as well!
