Sorry to necro this thread, but I didn't want to start a new one.
Last night I was trying Route Mode for the first time on Death Valley, and it seemed to fly me quite high. When I approached the waypoint from which I was to commence my attack, I tried to make a descent. Apparantly I did so to fast, because something happened and I just continued to descend until I crashed. None of my collective inputs mattered, although my rotors were still spinning. I'm assuming I descended too fast.
I guess my question is twofold:
1. How is flight elevation handled in route mode?
2. How do you make a controlled descent. Obviously if I pitch the aircraft forward I gain speed.
