Remote Kill Switch
 
Anyone know where to find a wireless remote kill switch? Like those on small 4-wheelers.

robertdjung 03-26-2008 02:50 PM

wireless?

I can think of a way to make one using one of those cheap forward/reverse radio control toys, but it wouldn't be very reliable. I didn't know they had "wireless" kill switches.

In an emergency a wireless kill switch might be unreliable especially if battery condition is unknown. A hard wired switch might be less weight and less expensive.

i just got my northern tool catalog they have a switch for 10 bucks, but it not wireless.

Yeah, I was thinking of one of those when I read this thread... But...

Anyways... those 27MHz ones absolutely stink. You get like a few feet before they die out. You'll need to get like a 75MHz transmitter (3-4 channel will work fine)... ect...

It's not gonna be cheap though :sifone:

That's why I said that it would be unreliable if it was one of the cheap ones. Not all 27MHz systems are bad. My Nitro R/C truck could go about 1/4 mile before I started losing signal.

I agree with kibble I have a MGT 4.60 and I had it way further that 1/4 mile and still kept going.

just was woundering why are you wanting a wireless kill switch and not just a wired one.

you could just make an 'external' system, a servo motor connected to your existing on/off switch via a linkage.

[pic of servo motor on my rc car. that red piece moves backwards and fowards]
is that what u were talking about kibble, or did u mean wired up? :huh:


talk to your local hobby shop, they sell servo motors for r/c petrol cars. [not cheap chinese kid stuff] and just rig it up..

kibble 03-28-2008 12:34 AM

No, not with a servo, I meant wired directly to it using a relay.

jr dragster T 03-28-2008 09:19 AM

I think kibble has got the right idea. Just need a reveiver and a transmitter.

kibble 03-28-2008 06:51 PM

If I happen to have a cheap R/C or find one, I'll show how to do it. It's quite simple to do.

I want it for the safety factor. My son is only 5 and this is his first kart and I want to be able to kill the engine just in case he goes where he shouldn't. I have about 2 acres and there is highway near by. If you recall this kart is a bit extreme so my focus is safety. I will have it governed way back and maybe even throttled back to help keep him in check until he gets used to it. He will be able to grow into it for quite some time, that's why I am building it on the extreme side. Just want to make sure he's around to enjoy it for years to come.

Dude, thanks! That is exactly what I'm looking for. The price is a bit steep but worth it.

kibble 03-28-2008 08:25 PM

Well after you mentioned that it's for your kid, then yeah it's worth it. :iagree:

turbodiesel_67 06-02-2009 06:20 PM

I bought one!! Don't know how to wire it .... :(
 
I actually bought one of the switches from this company, but when it arrived, there wasn't a shred of documentation on how to wire it. I planned to hooked it up to my 100cc 2-stroke. Not sure what to do next.

Has anyone bought/used this switch?

The switch has one white 4-pin connector that seems to be for some specific ingnition system, and 2 separate blue/white leads.

I've contacted Extreme Motor Sales, if they answer, I'll post the result here.

Purposely kept alive to provide background for "noobs".
I like it. My personal preference.
