What's the issue you encountered?

When I use any of the setAngleRateControllerGains, setAngleLevelControllerGains, setPositionControllerGains, or setVelocityControllerGains APIs, the quadrotor rapidly loses altitude. I am trying to understand why this is happening.

Settings

Deafult single quadrotor

How can the issue be reproduced?

I am using this script to control my quadrotor through checkpoints and adjust the PID gain:
