RCEKS-5G - the 5th Generation of the 2-stroke RC engine kill switch designed and made in Australia. With new updated firmware and wider operating voltage. It is a 3 in 1 version (version RCEKS-2G, RCEKS-3G and RCEKS-4G). It works with most 3 or 4 channel radios. RCEKS-5G will automatically kill the engine if you have a low battery, radios glitch, lose connection, or power loss.
