Look at this image.
The thing is i want to find new position of the blue dot if i rotate aircraft

I start from positioning the center of an aircraft then i move whole model to geometric center (red dot)
i already have fixed airframe (alieron) position so i know where to translate it when no rotation is applied. But then rotation appears:

I know the front direction of an aircraft, its up direction and its right direction, but i have strange feelings about my solution so i ask here:
I want to do something like this:
- go to red dot
- multiple vector AB X value by normalized right direction
- multiple vector AB Y value by normalized up direction
- multiple vector AB Z value by normalized front direction

and here is the deal i think this will position the airfoil in the right direction but with wrong distances? am i right what i need to do?
