Since I reduced the number of flights I am flying better again! As a freelancer and in my age I have the luck to be able to fly as often as I want.

All control inputs are reversed, especially up and down which can be very expensive. And it's windy like hell. Since almost two weeks I am flying much less batteries and even gave myself a day off from flying to allow my brain to recover. And I am feeling much more fresh and I have more fun again! Please write in the comments if you know this feeling or if you experiences something similar.
