I have a bunch of continuous rotation servos that I really want to use in my cockpit because they are smaller than steppers and fit better inside 2" instrument casings. The problem I am having is that when I test the servo, it spins and spins and hitting stop simply reverses the direction; it goes until I unplug it. I'm not getting expected results from running it connected to P3D/FSUIPC, either.

Is there any way to use these servos with Mobiflight?

Hi Jmcmanna,

welcome to MobiFlight!

Did you use the TEST-Button in the MF Wizard?
Then the servo can sometimes hook and does not run until the doctor comes, but until the power fails.

Have you ever tried the servo tutorial at the top of the menu? Here are some valuable hints for handling servos.

Normally the servo is stopped when it is controlled from the MF-Run mode.
If the servo can be controlled as in the tutorial, it should also be possible to control it via P3D / FSUIPC.

I tested the servo in MF....hitting "Test" causes the servo to spin endlessly, and hitting "Stop" makes the servo spin endlessly in the other direction. I have tried a couple of different servos and they act the same way. My regular 180 degree servo works just fine with MobiFlight. I did go through the tutorial and successfully built the flap gauge with a regular 180 degree servo.

Ok, I meant, if you have also tested the flap gauge with the 360 ° servos.
I think it's possible that they will work properly

Yes... The "TEST" Function in the Config itself at Display Tab. (Not the Test Button in Main Mobiflight window near Stop and Run) is the Key.

I not know your Servos... Maby they can´t work with MF.... But you can simply find it out in the Test Modus.

Please always note.... The "Range" of Value should never be override (Whatever on lower or upper end) .
If you define a Value Range for example of 0-1000 you should get shure the INPUT Value ( Or the Testing Value) is NEVER below 0 or higher then 1000 .

Now simply try out to change the Rotation Set Value ( From 180 standard to 360 for example) .... Try out multiple Test Values....
I Would recommend to use a Range from 0-1000 and use Testing Values like 100, 200, 300, 400 and so on.
Simply find out what happend in this situations to understand the logic how "YOUR" Servos work !

Hello again,
How you can fix it? I want to use 360' servo (mg955) for Spoiler. However, when I connect to my servo on Arduino, the servo starts to rotate continuously. And if I click to test button, then the servo starts to turn the opposite rotation. How can I programed to servo for example to turn 220 degree.

However, when I connect to my servo on Arduino, the servo starts to rotate continuously

Thats technical not possible i think !

For sure there exist 360° Servos (instead of the standard 180° Servos)
BUT
From my point of view a SERVO have a clear Start end End Position. It can not turn "continuously"

So in theory a servo with a specific gear e.g. can turn 8 Times e.g. But not endless!

Please confirm we have no translation issue.
do we talk about a SERVO or about a STEPPER ?

Was there a solution to this, I'm having extactly the same problem using MG90S servos. If I adjust the max rotation percentage to zero it stops the servo. if I go plus or minus it gets faster but still constantly rotates
