Descent, speed and more

Hi!

I am new with ArduPilot and I have some problems:

1) In AUTO mode the plane will not descent if the next waypoint is lower then previous...? Let´s say I need to descent from 300 m to 100 m, how to do this in AUTO mode?

2) It seems that the plane is flying 12-14 m/s, how to increase the speed in cruise? In setup I allowed to use 90% throttle (but it´s using only 50-60 maybe). I see where I can change the airspeed, but I don´t use AS sensor (PITO tube). Where can I change the ground speed???

3) my plane (FPV Raptor) is flying slalom some times like in this video: http://youtu.be/l-3_QgSBbrE  Why?

Thanks!

    1 - Ascent or descent will be automatic.  If it is not happening, you need to tune your parameter set.

    2 - There is no direct provision for speed control without an airspeed sensor.  Speed can roughly be controlled by proper throttle setting, and there is a provision for minimum ground speed.

    3 - Your "slalom" is due to your needing to tune your parameter set.
