Why can that happen? When I'm switching between Stab-Althold-Poshold quad kinda switches motors off for a sec. Is that normal?
-
The GPS modes are mainly velocity controllers. When you change the sticks you are effectively instantly commanding a different velocity. The response is to accelerate as quickly as possible. For bank angle, that means max angle. For throttle, that means full or zero.
Banging the yaw stick back and forth you can really notice the high motor speeds. Then leaving the yaw stick at max, the motor speeds taper off because they have reached the requested rotational speed.
When you switch modes, it is probably switching into or out of one of these velocity modes or there is a step in the requested value.

Thanks for the explanation. So basically that's a normal behavior?
-
It can be. You could upload a video and describe exactly what mode you are switching from and to if you want more exact info. Also, your settings (uav) file and describe what you have set non-default in AltHold, FWPF verticals, etc. settings.

I too have noticed that happening when I switch flight modes.

Same here.
Jump up or down sometimes when I change mode
PosHold to VelocityRoam
VelocityRoam to GpsAssist
VelocityRoam to PosHold
Also
Position 6 i have a ReturnToBase when i change to this all well the ship returns normally, but when I close TX (FS) sometimes develops a high return speed and always rotates (like ruder).
