I set damper up to 100,000 with the only effect being the surfaces moved slower, but inertia remained almost the same (it did go down a little bit but at a huge loss of elevator movement speed).

Set the damperMultiplier in rotators to high number
And Add mass on it

Make the elevators massless until you find a better solution ig

@Pita
Yeah we should remind them to fix that in 1.10

@Pita
Oh so I had it backwards

No u

@FishMiner or INF

Try adding damperMultiplier into the left empty box in jointrotor if you're using overload, and in the right box add either 100, 10,000, or 100,000.

@switdog08 Ill try dampening at some point and then I will try that, thanks

loloolo get rekt

@Wallaby
Try increasing the weight of the elevator. Because of how SP's physics work, it will be less torgue-y if the weights on both sides of the rotator are closer to balanced.
Also, pretty plane.

@Kernels I tried that

I think maybe mass scale. All that weight is being moved all at once so that may be it

@Kernels Didn't work. Thanks for the help though.

Maybe you need to disable aircraft collision?
