propeller expression

hi, i'm working on an animation that will have a propeller attached to a submarine, the way i thought to do this would be to parent the propeller and submarine to each other and write a simple expression to make the propeller rotate as the sub moves along a path. am i on the right track and if so what would be written in the expression.

thanks.

I'd suggets to group the propeller with itself to create a new transform node to it. Then parent the group (not the propeller shape) to the submarine. This will allow to transform the propeller freely while it still moves with the sub. Then create the expression to the propeller's (not the group) rotation. For example:

propeller.rotationZ = time * (some value);

I used rotationZ just for an example. Your may vary...

I did this in the past by just keying the first rotation of my sub's prop, and then in the graph editor, setting the keys to pre and post infinityuser added image

Can you change the speed of the rotation just by adjusting the keys later?

I just do it the way Ragecgi mentioned. in the graph editor.

not sure on the syntax the way kbrown suggested would be the best way
