I've been reading forums and watching videos prior to purchase but I finally pulled the trigger and bought one. The rain has finally passed (for now) so I think I'm about ready to fly. I've charged the batteries, unpacked everything, and downloaded the GO app, etc. although I've not turned anything on yet. I've FAA registered the drone and have chatted with the local airport manager (small unmanned airport is 3.3 miles away). Before flight I think I need to check imu and calibrate the compass. Anything else? I doubt that firmware is up to date...can I at least try flying without an immediate update? I'm on iOS and plan on using an iPad air2 so I hope that's not problematic. Finally, the sd card was already in the camera slot when unpacking. Is it formatted, or will it format when I turn on the RC, or do I need to format it? Thanks for any help.
