And you are in fact arming like the picture says then correct? It could easily be something like endpoints and middle points. You need it right on the throttle and yaw.
I had seen this on another group. It is insane how badly they over reacted. If they were afraid for public safety, imagine how safe a quad with no operator....
It also will be slower at times, if the quad was not apposed by gravity or air resistance, and the props somehow still worked the 4.7 pitch means that they would move 4.7 inches per revolution. Imagine the speed of that haha.
I had seen a few other sited report on this last month. I think it may be a smart move for the company, as they are plenty big enough to take a lot of DJI's business.
