RC Kill Switches

Has anyone found a good reliable electronic kill switch
There was some awhile back and some tried the rckill switch
but there was some trouble with them
I have a return spring setup that may help some
but i would like to have a kill switch that shuts off the engine
with low voltage or loss of signal and a switch just in case.

Are you looking to shut off a magneto engine or an EI engine?

There are lots of options for EI engines which are completely solid-state and optically isolated. As for the magneto engines, unless you're willing to run a separate battery pack to power a solid-state kill switch, all of the commercially available units seem to use a relay which has the risk of vibrating closed or causing RF interference in your power bus.

Technically speaking

You could make your own. I did one years ago for my 1005 from a relay switch that I got at an electronics store. Wire it to the receiver to open the switch, and wire the black wire through the switch and to ground.

This way the engine won't start unless the receiver has power. If power is lost to the receiver then the switch closes and the engine is killed. If you have power to the receiver then its a good bet you can shut the motor off. It was intended to prevent chicken dances should you crash and the battery fly off, but I removed it from my helicopter once I built some power redundancy in it.

42% Products makes nice stuff and has good customer service. They make a relay based magneto kill switch which will work with your Spectra. I ordered one, and had it mounted to my helicopter frame while I was trying to break in my first Wally motor. The relay failed due to vibration after about 30 minutes, but 42% Products replaced it for free. I never reinstalled it.

^^^ The kill switch in your link won't work with a magneto.

There are many options for an EI engine, but the only commercially available option for a magneto engine seems to be a relay-based kill switch. It would be possible to build a solid-state magneto kill switch using a simple transistor, but it will require either an external battery or a capacitor to power it. Capacitors don't do well with vibration.

I have never seen anyone produce a schematic or a prototype for a magneto kill switch which does not require an external power supply.

A+ for the Killer RC unit.

Get the Killer Bee Kit 1. I use the Killer Bee v1 for Futaba radios. Great company to deal with.

Check the killerrc website. They have different kits that are compatible with different radios. I use one on my baja and it works like a charm. You can add a buzzer or LED for visual and audible verification.

Isnt just using the choke an option?
I dont have a kill switch and have the choke there instead.

Setup is everything, All my heli's can fly far better than I can pilot them

Using the choke is an EXCELLENT option, or placing your hand over the venturi if you have one of those.

Pretty hard to kill it in flight with the choke. For safetly reasons, i think the killer rc option is best, if something happens at least you can take out the power while flying. Lets face it, alot can go wrong in a hurry. I have killed my rc 1/5 scale cars on occasion. Saved taking someone out for sure.

Just my opinion.

Clear this up for me . He wants a kill switch on his radio. The radio can stop the engine already with throttle trim etc. Then if there is a loss of signal the failsafe could do that too . If you have radio failure ,not set the failsafe correctly no switch is gonna help you.
Am I missing something here?? Sorry it's been a long day.

Yes, you can kill the engine with the throttle trim, failsafe if radio goes down , nothing if the flight power fails and hopefully the spring if the servo horn comes off (mine did last week)...

BUT a killswitch will sort out a jammed throttle servo, is quicker than cutting trim down and is very convenient for switching off simply and quickly on a landing when blades are spinning without messing about with trim or stressing the throttle servo low end point (not saying that set correctly it does), adds to safety when approaching a landed spinning heli..and is just convenient and handy and weighs very little.

Don't want one? Don't use one.. I like mine..it's the 42% version and been on there a long time and still works.

If it needs killing in flight, use the trim or throttle cut on the radio. But I doubt that you'll have time to do much of anything, including hitting some kind of "kill" switch. When it all goes pear shaped, the thing crashes pretty quickly.
