VTOL 4+1 fixed wing 4 motors do not stay at constant pwm in quad mode


I’m doing 4+1 VTOL and I have a strange problem. When I make the throttle level 100% in Quad mode, except for one motor, the other motors do not reach the max pwm value and the pwm values ​​decrease. I did the Esc calibration. This issue is only resolved when I set the Q_ESC_CAL parameter to a value of 1. Will it be a problem if this parameter remains at 1 during flight? Or how do I solve this problem?

Under what conditions are you testing this? There likely is no problem.
