How to increase descent velocity

ArduPlane
1

Hi,

in AUTO MODE, when plane passes from Waypoint to more elevation to another Waypoint with less elevation, automatically reduce motor and glide. I need to set near this two Waypoint and increase descent velocity also without reducing the motor. How i can?
is onlu TECS_SINK_MAX ? or orther like PTCH_LIM_MIN_DEG and AIRSPEED_MAX ?
i use Airspeed sensor

Thanks

It depends on the actual performance of your plane.
Can it get a greater sink rate if you manually pitch it down more, at 0 throttle, while not flying too fast?
If yes, you should follow the TECS tuning guide to adjust the TECS parameters and unlock that extra potential.

I don’t think not reducing the throttle is a good idea. Why do you insist on that constraint?

now glide like glider from one waypoint to other waypoint ad not in correct elevations when the waypoint is too near. I not want this i want fly like ACRO.

now cruise speed like 150 km/h and max structural body is 350 km/h not gave problem to unlock this parameters… try with TECS_SINK_MAX… other parameters to unlock?

i find also TECS_VERT_ACC maybe need to change also this
