An engine kill switch is a must have for all two-stroke engine powered RC cars. An HPI Baja is 9.4kg, and a Losi 5IVE-T is about 17kg these are the two most popular 1/5 RC models today. As you can imagine these cars travelling at speeds over 60kph can do a lot of damage to a person or property.

Have peace-of-mind with Killer RC's Super Bee, once installed; the Super Bee will detect when your battery is getting flat, damaged, or when your car is out of range then, it would cut spark to your engine and cause your vehicle to come to a halt.
