Can you animate a joint without it having any effect in the physics world?

I am trying to animate some parts of a drone without them having any consequence in the physics world.

For instance, let's say I'd like to animate the four propellers of my drone, I could attach an animation to the model with SetJointAnimation for each propeller to make them rotate around their axis. The problem is that when the drone is dropped from a few meters, the constantly moving propellers slow the fall of the drone down. How can I prevent that?

you have 2 possible solutions:

You can write a system plugin for that and just update the visual using ogre directly(client side plugin).
Or you use an animated ogre material on the visual which is rotating... (Ogre Rotate texture Material ref )

EDIT:

it might possible to specify no collision for the link, but I think that it still influences the sim speed(because there are still forces applied to the links...)
