I really get a kick out of this quote at Tower Hobbies:
"* This unit is designed and manufactured for an expert driver at racing competitions only.
* Wiring and soldering are necessary. Please wire this using your own responsiblility.
* Because this product is designed for racing competition, it is not equipped with the thermal protection circuit. It is likely to ignite by the paradox and the overload of the power supply.
* Please promptly stop and check this unit when you feel there is an abnormality after you have started using it."
"[I]gnite by the paradox..."????
