Is it just me, or is this the most compact and tidy layout you've ever seen. That electronics box is perfect, and makes everything so tidy. The tranny is perfectly place low down on the center-line of the chassis, yet doesnt hang out the bottom at all. As for battery trays, I would suggest some like
