Airbrake animation bug

[Scorpion_SK]

I have weird animation bug on the stock airbrake part - when airbrake is deployed, it's animation angle not matches the deployment angle which is set in the settings of the part.

Screenshot of the bug:

I have deleted all mods, started a new savegame, even reinstalled the game completely but the bug still persists even on a completely clean and reinstalled game.

KSP 1.9.1(x64), Windows 7.

Have someone seen the same bug before? How to fix it?

You have found a new bug.   In older versions of KSP the "Authority limiter" ran from 0% to 100% and the full 100% was 70°.

There are now two sliders, "authority limiter" and "deploy limit", but it only makes sense to have the second for airbrakes, and only the first seems to have effect on deployed airbrakes.  Recently (around 1.7.2, I think) the  sliders on aerodynamic control surfaces changed from % to degrees, and the separate control for "deploy limit" was added.  It looks like Squad made a mistake on the airbrakes at that point.

We could report it on the bug tracker.  It is very likely that someone in the forum will see how to repair the problem by changing the configuration file.  Then we can patch the problem ourselves (on PC versions of the game) and also put the fix we want on the bug tacker.
