Today I attempted my first descend in manual mode which did not go well. I was about 60m high and in a hover when I switched the controller to manual mode and my phantom dropped like a rock. The phantom appeared to almost free fall, I quickly switched to ATTI mode and hit the throttle, I was barely able to save the quad from a very hard landing. My goal was a fast descend from high elevations to land quickly in situations when the battery is low. How do a properly descend in manual mode with out my phantom dropping like a rock.
