Electronics Compartment Ring

I designed this ring to take the place of the radio box in the original model. This lets me access the entire inside of the hull and gives me more choices of where to mount electronics. It saves weight and lets you play with the center of gravity by moving things fore/aft. I put an L in the top of the ring to help prevent water from entering the hull. The L allows water to spend its energy against the lid and fall back down instead of forcing its way past the gasket. For a gasket I use adhesive backed neoprene strip. I haven't had any water enter the hull since switching to this setup. If you haven't printed SlightlyAbnormal's model yet you really should, it is an absolute blast to run!
I used hot glue to adhere this to the hull, but epoxy would work well too. Whatever you use just make sure it is a water tight join to the hull.
