No matter how I launch drone, I hover above VPS range to check for accurate GPS hold and give drone time to save home point. Sometimes I resave homepoint after I know I have good GPS hold just to be on safe side when flying over water.
Gesture Palm Launch works really well for me - one gotcha to be aware of is that it seems to lock the camera to ‘camera’ mode and you can’t switch to video. The trick is to go into the the flight mode menu after palm launch and change it to standard etc. You can then freely switch between photo and video mode! ...and then change back to gesture mode if you want to palm land.
