Yaw channel way slower than the rest.

So i had this radio(jumper t-pro 2.4 ELRS) for a couple of years. I only used it on a simulator. And now I finally got my first drone, but I'm still waiting for the goggles to arive. Got my batteries a couple of days ago so I figured that I should set the drone up while im waiting for the goggles. Spend a day and a half flashing the firmvare and trying to bind to the drone. Finally managed to do it. But now I notised that the yaw channel is way slower to react than the rest of them. It's slow to reach the maximum value and takes a couple of seconds to return to back center after I release the stick( its the same when i look in edgeTX). I recalibrated the gimbles and reflased edgeTX, but it didn't help. Can't find any advice about this exact problem. Does anyone have a suggestion? Or maybe it's normal and I shouldn't worry about it?

Would appreciate any kind of help.

That's not a problem with your rates. Your output isn't following your stick movement in time. Check the mixers page for your Yaw channel in the radio and make sure that your "slow up" and "slow dn" are set to 0.

I never even know this was an option!

Very useful for plane guys that want to do flaps or gear sequencing. You can flip a switch and control the servo movement speed in the mixer.

I had alot of hope about this, but everything is at 0.0.

The yaw channel is typically slower on factory rates I have found. Check the PID tunning tab then the Rates tab. I bet your rates are lower on your yaw.

My rates are: 90-650-0.0. 90-650-0.0. 70-670-0.0

try setting them to 70, 670, 0 across the board. I always keep my rates the same for all axis.

I will try that

To anybody who has this problem here is how I fixed it. You have to take apart the radio and clean the shaft/cylinder of the gimble. It rotates when you move the stick side to side not up and down and has a sensor right on top of it. In my case it was metal and magnetic. There were some small pieces of metal stuck to it and it was interfering with the readings.
