Having a transport and too much time on my hands, decided to try hovering. Actually, all I am trying to do is show pilots that if you can control the 3 axis, it can hover.
So what I did is I know I have airflow for the ailerons, provided airflow for elevator and to get airflow for rudder(not consistent), I decided to incorporate thrust differential for the props. I used a GWS mixer, reduced the rate of rudder and provided some expo. Result was a nice differential range which allowed me to keep the wings level.
Also, explored putting the battery vertical in the nose to improve the balancing. So here is the video practicing 3D hovering. For those who try/do hovering, if it get to far out of whack, get out and try again. Otherwise, you will dump it.
