Hello Community,

I'm reaching out to seek assistance with regard to controlling the Sentinel drone in Position mode.

When I transition the drone into Position mode, I've noticed that there is no response from the throttle until the throttle stick is pushed above 50%. Once it surpasses this threshold, the drone begins to take off and ascend, and everything operates as expected from that point onward.

I'm curious about the reason behind this behavior where there's no response until the stick exceeds 50%. Is there a way to adjust this so that the drone can initiate takeoff immediately when the stick is raised from zero?

I appreciate your help in shedding light on this matter and look forward to your guidance.

@SMRazaRizvi That's expected. In position mode the drone is holding altitude. In order to make it descend you move the throttle below 50% and to make it ascend you move the throttle above 50%.

@SMRazaRizvi please refer to the PX4 documentation, position mode behavior is detailed here https://docs.px4.io/main/en/flight_modes_mc/position.html
