I am an experienced photographer but very new to the world of drones. I just purchased a DJI Phantom 4. I would like some input on the following as I have never seen it explicitly mentioned in the literature I have read. You can use both the sticks on the controller simultaneously during flight, am I correct? That is, I can make the craft go forward (right stick up) and up (left stick up) at the same time. The reason I ask this is: one combination of the two sticks operation, namely bringing the sticks inward during flight, will result in the motors stopping and the craft falling out of the sky. So one has to be careful during the two stick operation to not go near that particular combination. Am I correct in the above observations?
