ok , so as I was previously indicating, I will use the second plate I have to make a raised platform. The temporary spacers will be swapped for custom vibration isolators normally used for camera gimbals.  This also raises the sensors and gps module higher and farther away from DC ESCs the DC power wires and the 110v /220v wiring as well to reducing any possible interference. Here is the 3D model and I am printing 12 pieces to make 6 vibration isolators now.
