The hydras report their position from the center of the base station (the green orb). Whatever is your parent (e.g. pawn's root component) of your motion controllers will then act as that center. So to move the positions forward you need to calibrate the hydras to a known point. On page 3 in this thread we talked about one calibration method, which is to make a T-Pose with your arms and hitting calibrate (capturing the positions at that pose), which then gives you the offset from the base to the shoulder midpoint (and arm length from the vector/2), you can then add this offset so that the controllers appear almost 1:1. You can set this offset as your controllers' parent position. E.g. make an invisible component parent the two motion controllers and just set that component's position as the offset and it will work as you expect it.
There are other calibration methods which may work better for VR, e.g. if you place your controller by your face (you know your hmd position) and then extend your arm and take a second calibration point, you get the same offsets but with higher reliability to get closer 1:1 match.
