The owner's manual I have for my '07 rustler xl-5 says that the xl-5 can handle 9.6V. when I asked the Traxxas Live Chat Support they absolutely refused to acknowledge that they had ever said that... What are your guy's opinions? Could it handle it or would it just burn up? (Now that I think about it my old non-waterproof xl-5 burned out on 8.4V...)
