Took this when cleaning after a trip, I think I missed the kitchen sink! Probably one of the most important add-ons would be my power source chargers, when the controller runs down in the middle of a flt I can plug into the micro port and keep going.
Let's look at it another way. If it's calm on the ground it does not mean its calm up higher. The best way to Guage is to look at your drone in the air and look also at the rpm on your rc control. If it rises and falls it's likely attempting to compensate for wind. Also when flying around objects or bluffs winds can be redirected. I like your kit but better to look at trees if there are any, birds if they are heat soaring off a Ridge for example or just lick the old finger for low flight. In theory if it feels too windy one may choose to not fly and save the $ for a GPS locator. Lol
I have added a Firehouse strobe attached to one of my leg extenders to my tool bag. This sure makes it easier to spot my drone at a distance and a simple 360 yaw tells me which way it is facing without even looking at the screen.
