Killer RC Engine Kill Switches

Killer RC makes engine kill switches aimed at owners of petrol and gas RC vehicles — typically large-scale 1/5 buggies, monster trucks and on-road cars. The kill switch is a safety device that lets you remotely shut down the engine if the vehicle becomes uncontrollable or you simply need to stop it quickly. They suit serious large-scale hobbyists who already understand 2-stroke engine basics and want an extra layer of safety on top of standard radio failsafe behaviour.

No — Killer RC kill switches are designed for petrol/gas RC engines that use a spark ignition system, not glow-fuel nitro engines. The switch interrupts the ignition circuit to stop the engine, which only works on spark-ignition powerplants. If you run a nitro (glow) engine, you would need a different shutdown approach such as a servo-controlled fuel cutoff. Always check that the kill switch you are buying is matched to your engine type before installation, and follow the wiring instructions carefully.

We currently stock just one Killer RC item — the SBK3 kill switch — in our Australian warehouse, so availability is genuinely limited to that single SKU. If the SBK3 suits your large-scale petrol setup, you can order it locally without needing to import. For Australian buyers needing different ignition kill switch options, we also carry HiLantronics, an Australian-made programmable kill switch brand, which gives you a local alternative within the same product category.

Our Killer RC range consists of a single product at the moment: the SBK3 kill switch for petrol/gas RC engines. Because it is a one-item range, the live Killer RC category page on our site is the most accurate place to confirm current availability and pricing. If the SBK3 is not in stock or does not suit your specific engine setup, take a look at our HiLantronics range — those Australian-made programmable kill switches cover similar large-scale petrol and gas RC applications with several model options.
