My checklist is this... all mental of course:
Turn transmitter on, turn wi-fi booster on, turn Phantom on, go to networks in cell phone, wait until Phantom is connected, go to Vision app and select camera. I don't need no stinkin' written checklist! Oh, yeah, I've forgotten to put the SD card in as well! Wait! I'm the one who always forgets to hit record! I did it again today. I was near some railroad tracks and as luck would have it I was in the air when a train went by. Too bad I wasn't recording. There will be another time.
