I received my Phantom 1.1(.1?) from B&H a few weeks ago. Upon unboxing, I connected to the NAZA assistant and upgraded firmware to 4.02. (And I'm thankful to this board for flagging the fact that I needed to set the receiver to D-BUS, or that could have been very frustrating!) But I read about setting defaults or download defaults or some such, and I don't know what that means. I've had the machine out and it seems to be working fine, but I'm curious...am I missing something, or is the "default thing" only needed if you're upgrading from earlier versions? Thanks!
