I know this is still prototype stage photos but the arm mounts look VERY similar to the XRay/Corally style arm mounts.
Please, please, please make it so the mounts are servicable without having to remove the bulkheads. Maintenence (for me) was a big issue on some of the older XRay cars and the RDX. It took forever to change some things.
Make it perform, make it easy to maintain, make it durable and you'll make a ton of $$
