I like the concept, but I do have a few suggestions. You might be able to save some footprint on the battery mount by changing from the folded sheet metal to a few pieces of aluminum 1x2 angle (or something similar cut out of some 1x2 rectangular tube) or something similar. Also, I'd be very wary of having the battery on the drop down bellypan, that seems a bit sketchy. As previously mentioned you're probably better off designing a few drop down brake pads and making sure that they comply with the rules (though the 2015 rules haven't actually been announced yet). Not only would you not have to drop the battery, the bellypan would go a long way towards stiffening your frame. Best of luck with the beta testing, and nice job on the design head start, you'll definitely have something you really like by build season.
