So next I need to make this compartment usable. I cut out the right and left side of the motor controller mount out and removed the zip ties for the wiring. This has created a slightly deeper and wider space to work with. I believe I will hot glue in some fleece fabric and soak it in resin. If needed I will reinforce from the back side only to keep this area open. I am not worried about weight as this is designed to haul around a 300 pound payload.

Ok great, a couple hours later I have a fiberglass compartment
