Speed Limit Side Effects

I'm developing a rocket with some built in mechanics and I noticed that the artificial speed limit causes the rest of the vehicle to slow down/pull when I articulate certain parts. I built this to demonstrate the behavior. The rockets have more then enough thrust to overcome the push of the servos.

I'm not sure what could be done about this short of removing the speed limit. Perhaps add exceptions for certain situations? Once again, I have no idea how you would define those exceptions.
