I have seen this topic mentioned several times recently. However I thought some of the members may be interested in my experience yesterday. I was flying with my Mini 2 from my favourite hill along with other drone pilots. Some of these pilots were training noobies. As I was flying one of the instructors passed by me and raised both hands making a pinching sign with his thumb and forefinger? He did the same again on his his return? After landing the Mini 2 I walked over to him and asked what he was signaling to me. He said you are flying with your thumbs on the sticks which is not precise. You should be pinching the sticks for greater precision. I said I am flying generally in a wide open area so precision is not really necessary. He just replied saying you should always fly with precision and the only way to do that it by pinching the sticks. End of story!?
