How to Get Component Velocity in World space?

Ref_Prop and Ref_Rudder is reference point in my blueprint. Not visible and no collision.

I want get SpeedOfComponetX and SpeedOfComponetY. But non of them work:

And I tried to enable collision in reference point, but I got this:

**I addforce at propeller on Y direction, so that the Pawn is rotating, so that propeller and rudder goes around the Cockpit. The velocity of propeller and rudder should in opposite direction, and definitely can’t be same. **

But as I showed in screenshots, I get same value for different component, I guess the result that I got is the velocity of the root object, not the component. How to get the velocity of component?

Came across this and have the same question. Did you ever figure this out?
