Motor won't go backward

Hello everyone =) I face a problem I have a boat with 1 engine and a servo for the direction, the diretion is well taken into account in the menu servo output on the channel N ° 1, but when I put throotle that is on the N ° 3 the engine runs at mid revs , what I would like is that the engine is stop at neutra,l forward when I push the handle and vice versa for the back, could you help me accomplish this pls?

Best regards

Your question is a little hard to understand but it sounds like the ESC is not set up for forward and reverse.

First thank you for answering me, I’ll be clearer: in “pass trough” no problem the esc goes forward and back but as I attribute the function throotle, it goes into a spin, a configuration idea?

Best regards

Can you post a log of this behavior?

Hello, sorry for the long absence but I was very taken (future dad) so I made an update and everything is back in order!
I made the necessary adjustments at the PID but I would like the boat to slow down before reaching a waypoint,
can you give me the relevant parameter please?

Best regards
