The RCEXL Opto Gas Engine Kill Switch V2 is an essential safety device for any petrol-powered RC aircraft, allowing you to remotely shut down your engine directly from your transmitter. Designed for use with electronic ignition systems, this kill switch provides reliable and interference-free operation for total peace of mind.

Using fibre optic coupling, the ignition system is completely isolated from the receiver and radio system, eliminating the risk of electrical interference. This ensures clean, stable signal performance even in demanding setups.

The unit is simple to install just plug it into a spare switched channel on your receiver. A bright remote-mounted LED indicator clearly shows when the ignition is armed, adding an extra layer of safety during operation.

With a high-performance MOSFET output, wide voltage compatibility, and built-in safety protections such as reverse polarity protection and automatic shut-off, the RCEXL kill switch is a must-have upgrade for any petrol RC model aircraft.
