This kill switch is fiber optically coupled to isolate your ignition system from your radio system.(no interference). Including a remote mountable bright LED to indicate when the ignition is armed.
This device allows you to safely and remotely kill your electronic ignition equipped engine form your transmitter. Shut down the transmitter power or receiver to cut off automatically when kill engine.
This kill switch allows you to safely and remotely kill your electronic ignition equipped engine from your transmitter, giving you a sense of comfort. The engine can be remotely shutted off even when it losts signal or the transmitter is turned off.
PIC12F675 controller. Fiber optic coupled input/output. Li-Po/Li-ion/A/Ni-Mh/NiCad input. Up to 20 Volt 16 amp MOS-FET(IRF7) output. Low to 3 Volt 3 amp output. Low voltage drop-less than 150mv. Heavy gauge wires, universal connectors.
How to choose a good gasoline engines for rc airplanes?
On the surface, choosing a gasoline engines for rc airplanes seems simple. But once you dig in, it gets more complicated. Between technical differences, unfamiliar brands, and unclear features, it’s better to ask the right questions:
Usage: Will you use it daily or only occasionally? That heavily influences the right model.
Budget: No need to go for the most expensive one right away. What matters is the value for money.
Key factors:
Durability, build quality, lifespan
Truly useful features (not just marketing buzz)
User reviews, especially after weeks or months
Availability of customer service in case of issues
We’ve cross-checked multiple sources: Amazon data, detailed reviews, search trends… and a bit of intuition too—because numbers don’t tell the whole story. This mix allows us to build our ranking, which we update regularly. The goal isn’t to just list names but to guide you toward what truly works.

What is the best gasoline engines for rc airplanes? It depends on your needs, but the top 3 products are generally the most balanced options.
How do I maintain it properly? It varies by model. The best approach is to follow the manufacturer’s recommendations (yes, reading the manual is worth it).
Where to buy it with confidence? Amazon remains a solid choice: wide selection, easy returns, and tons of user reviews—hard to beat.
Do I need a big-name brand? Not necessarily. Lesser-known brands can be surprisingly good, with well-designed products that rival top names—at a lower cost. Don’t overlook them just because the name is unfamiliar.
What are the most common pitfalls? A super low price might be tempting but could signal major compromises (build quality, reliability, nonexistent support…). Also beware of product pages with no reviews or vague comments. Spend a few minutes reading real feedback—this is often where the most valuable info is.
