The blue side of the tray is the last remaining part I have left from my Fine Design nightmare. It's crappy with only the two "rubber band" tie downs he supplies but with a front bracket and Gorilla strap it works very well; still use the bands to secure the batt. wires. Underneath the tray is a piece of 1/8 inch plate supported by the original motor mounts, pipe wire mount and 1 nylon spacer in between. Clean settup but the CG is too high on the stock mounts. I intend to purchase the two piece Nitro motor mount and cut the spacers in half to lower it half the distance to chassis and eventually replace the alluminum plate with carbon fiber.
