Maximum drone lifting power

Hi all.
My drone was able to have a MTOW of 5.5kg.

Somehow I’ve changed a setting where now the motor power seems reduced and the MTOW is reduced to 4kg.

What setting could I have changed such that motors now deliver less total power.
Thx.

Need a .bin log from “before” the issue started and another one from “after”

Preferably logs with equal TOW.

Hi.
Is a parameter available to set max motor power output?

Send a .bin log and we’ll be able to see what your parameters are like.
There are things to do to limit power and other aspects, but it will take forever for us to guess what you might have in place.
Also list exactly what motors, props, ESCs, batteries and frame you have.

These params can affect motor/thrust output, some more than others, and there would be more :

RC* <-depents what throttle channel you are using
Servo* <- motor outputs
MOT_BAT_CURR_MAX
MOT_BAT_VOLT_MAX
MOT_PWM_MAX
MOT_THST_EXPO
ATC_THR_MIX_MAN
ATC_THR_MIX_MAX
PILOT_SPEED_UP
PILOT_ACCEL_Z
WPNAV_ACCEL_Z
WPNAV_SPEED_UP
WPNAV_SPEED_DN
PSC_POSZ_P
PSC_VELZ_P
PSC_ACCZ_*
RPM_*
TUNE_MIN/TUNE_MAX <- depends if you’ve got your TUNE set up

If you don’t know what any of these do, don’t guess and make things worse. Just post a link to a .bin file and we’ll check it out.
