Recently I have assembled a four axis UAV, wanted to test the performance of the UAV.
In the beginning, I used the stabilize model, controlled the UAV to translate, climb, descent, hovering, and its performance is very normal. Next I greatly change the rocker angle, the UAV performance is normal. After about a minute, I found that the throttle is out of control, and other RCinput is in control. I pull down the throttle, the UAV will not fall. Waiting for about 10 seconds, the UAV began to slow down to the ground at a very slow speed, but the motors don’t stop.
What's the matter with the UAV?
