No, there is no way to do this unless you make the mods personally. You can mount the throttle servo and tank from the underside of the upper deck. You can also use the MTX-3 engine mounts and smaller flywheel to help lower cg. But, unless you rig something on the steering servo, it is almost impossible with the design of the car to lay that servo down.
