Spline controller orientation

[itsGama]

Hey ! 

First, thank you for this amazing asset, I think it's very well made and it fits my needs perfectly, good job !

I have a small question regarding the Orientation of the spline controller. 
Currently, my spline controller is oriented like this (green lines) :



As you can see, it's orientation doesn't follow the spline perfectly.
I'd like to know if there is a way to orient my controller perfectly toward the spline. (Green lines should almost merge with the spline)

Here my are my parameters: 



I setup my controller on the spline using:

Code:

float nearestPoint = refSplineController.Spline.GetNearestPointTF(transform.position, Space.World);

refSplineController.Position = nearestPoint;

Thanks you and please let me know if you need any additional information.
