I don’t understand your problem. It is similar to that question: “On ground floor is light on, why?”

Hi @xxin,

So I guess you’re using a BlueRobotics submarine or is it a custom frame?

and I guess you’re saying that after you arm the vehicle the motors start spinning but it descends?

There are many possibilities and it would be best to provide an onboard log so we can see what’s happening.

The first thing to check though is perhaps your RC transmitter. I imagine that perhaps channel 3 (throttle) has been calibrated so that it is always low. Maybe you didn’t move the throttle stick to the center at the last stage of calibration. This is just a guess of course because we need a log to know for sure.

Txs for using AP

Hi @xxin,

If you’re using a gamepad controller, can you share a screenshot of your joystick axis ranges, from the table view of the joystick page? This kind of problem has occurred previously when people reassign the axes without matching the ranges - note that Axis Z needs to be between 0 and +1000, instead of the -1000 to +1000 range used by the other axes.

We have some plans to make it harder for that kind of issue to happen in future.
