I try to practice my RC flying skills daily. I use a Dromida Kodo mini and a Syma X5C. Kodo inside if the weather is inclement. I break up the practice with each battery. So, for example, I will burn 1 battery just doing nose-in hover, another with flying the quad towards me with the quad facing me and another doing figure 8s etc. I wonder why the DJI simulator requires that the quad be powered up while I use the sim. I think I would be much more inclined to use it if I did not have to run the quad to do so. Anyway, was curious if any of you other folks do this kind of thing.
