0o a BEC failure! Have you tried powering it up via a Rx pack and the Rx? It sounds like the BEC coil is shorted if it's heating up like that and not outputting power to the other electronics... BrianG had a thread a while back on how to fix a busted BEC circuit. Hopefully he will reply here. If all else fails send it back to Castle and wait it out. Maybe you'll prefer to send it in first, I ALWAYS try to fix things before I claim warranty service.
