How to install a Dynamite RC kill switch in your large scale RC car 

Let me start off by saying you and DDM are a blessing to this hobby. Such an excellent video as always and a much needed one. Everyone running a 1/5 should have a kill switch and your video makes install foolproof.

Hi there! I'm hoping you may be able to shed a little light on an issue I'm having. Fitted the kill switch, everything appears to work as it should. Channel 3 is turning on/off the kill switch LED. However, when I start the engine, the kill switch cuts off the engine about 1 second later. I then have to cut the power to the receiver and turn it back on again before I can get any radio control. It sounds like it is an issue with the radio, but It can't be because until the engine starts everything is working as it should! If you could shed any light I'd be very grateful as I'm a bit stumped!

Awesome vid Steve I guess some people are having problems with the install and it not functioning right but your video makes it plain and simple thanks again Steve.

One of the most important things to note is that this will not work correctly unless the receiver is 4 channel. For example a Losi DBXL comes with a 3 channel receiver and the kill switch will partially work but the car will not turn off when it looses radio signal. The channel has to be a toggle channel 2 way or a 3 way. Basically the channel needs to turn off and the on. So just know that before you buy this. You might need a 4 channel receiver for this to work correctly. For the money this is a excellent kill switch. I have both brands and both perform the same task. The Killer Rc one just has audible tones to it and the option for different color LED lights.

Got the futuba 4pm pluss, do you have a video on how to set brakes to lock when signal lost, and how to set the signal lost? Just wounder so i dont Need to read 😄💥💥👍🏻good video 👍🏻

thanks man, I was looking for an instructional vid on how to do this! Thanks I appreciate it!

Well ok then! Thankyou for this short, concise, demo. Exactly what i needed. 💯

Great video. Are these switches any good as have seen a couple bad reviews but maybe due to incorrect install? cheers

Awesome video very nice how to vid on installing kill switch great job thumbs up!!!

I installed this on my HPI Baja 5T and the light doesn't come on for me and it just seems to have no spark I don't know if maybe I did something wrong but the engine won't turn over at all and I just got the engine running about a month ago and it has a new spark plug in it it's just been out of gas and I put the kill switch in today so I can go drive it and now I can't get it going maybe you can help? Please and thank you

Hey Steve great vid, to the point. Can u explain or show the direction of the jumpers? I have a 6.6 liFe and don't know which to remove (black one, red one or both)

You removed both of the low-voltage jumpers which would mean no voltage protection. I thought this Killswitch was capable of Lipo low voltage protection.

Good job Steve! Keep the vids coming!

Just curious so let's say the battery on the car dies will the switch kill the engine still?

I correction for you. The diagram for the voltage cutout programming pins is extremely unclear, so I followed your advice that removing both plugs deactivated the cutout. Wrong. REMOVING both pins sets the cutout at 6 v, INSTALLING both plugs deactivates the cutout.

Hi, further to my previous post, i was told to try another receiver battery 6v this put things right, It worked I also found that if you have a failsafe... already installed it can sometimes go into failsafe.. when connecting the battery, the light went out on the kill switch !! I then reconnected the battery and It worked fine.. its well worth checking the jumpers for correct voltage my thanks go to Richard at King Cobra racing uk for the advice !! Fred

Do you have to have a remote to make it work

hi is this kill switch the same as this one -- HPI KM ROVAN BAJA 1/5 5T 5B DBXL FM MCD REMOTE ENGINE KILL SWITCH thank you for your help

Is the stop.button on engine open circuit when not pushed,closed when pushed.mines reading closed on multimeter pushed or not

Very helpful thx!

I have an engine kill for my Losi 5ive and the box looks the same but it doesn't have the spade connectors, it terminates with a red futaba servo plug. Do you know if the button has a Normally open or closed circuit?

Hi i have a problem with my dynamite killswitch of i install it it Works but if i turn off the controller i have to asign it again to the aux1 2p .. whats wrong ?

Great info dude👍

I am trying to configure the kill switch of the dynamite brand in a futaba 3 pv control, I want that when I turn off the control the kill switch cuts the power to the. engine but I turn it off and it stays on

Thanks bro 👌

Thanks. Very informative. What tool is the three sides tool that you used?

So i want to buy a kill switch but wanna find a way to make it work without buying a 3+ channel radio(the one i have is 2 channel). Could i use the radio system from one of my other buggys to trigger the kill switch?(like when i steer with the remote control it kills the engine?)

Thank you very much

Where did you get that t handle screwdriver? I cannot find it for the life of me

Steve i got a though nut to crack for yahh. I have s spektrum DX4C with a SRS4210 receiver but some how the kill switch don't work??? Matter of fact then it's hooked up the spark plug does not fire.... do you have any advise of how to crack this nut

is it ok not to have no protection on it still work,

Hi, I just installed my kill switch, but when I connect to the receiver, the light failed to come on, after checking the whole system I then found that the light came on ..then off on connecting to the reciever..I changed the reciever but got the same result, I dont know what to do...Ideas ?? faulty ?? Fred

Works with any brand of engine?

hey Steve, I know this is kinda of a late message. I’m having trouble with the kill switch. I installed it to my exceed 1/5 scale buggy, and when I went to go plug in the NIMH battery and turn it on with the controller ( which is the factory set) nothing happen. I don’t know if it’s because I have the standardized controller. What would you think it is Steve/suggest ?

now do you get the failsafe to set? i have tryed over and over and mine will not work. can shut it off at the remote with the switch. but if i turn the remote off the light stays on.

Hi thx for the reply . I can kill my engine but when the system is installed and then turn off my controller it losses the setting it is on inhibet again it does not remember my setting wtf thats strange

Awesome Vid! Thank you )

Hey Steve I see in your Vekta 5 you have a stock servo and a Hitec servo is this a kit or a RTR kit and if it is a RTR did one of the stock servos fail on you just wondering because if you buy the stock servo by its self it's pretty expensive ?

@DDMSteveB I have purchased this Dynamite Kill Switch from DDM,I need help programming the Sanwa M17 with the Killswitch. Allocating a button for the kill switch isn't easy.Please assist.

Hi brill vid but what was that about business card ?

love the red T-handle tool set. do you sell it on your website? thank you

When choosing the voltage cut-off on the killswitch does removing both the red and black pins mean No protection or 6v Cutoff?

How do i set it up if i'm using a Nimh battery?

For anyone wondering why their vehicle won’t start now. The tutorial is wrong. To correctly install, switch around the red and black connectors on the ignition coil. Red is closest to the pull start and black is on the furthest connector.

Hi there I have a rovan baja q shorty with a 29cc engine in and I’m using the fly sky GT3C controller and have installed the kill switch following this video and I’m having trouble setting it on my controller if anyone can help would be great thank you

Thanks Steve, DDM Rocks.

Will the kill switch work on a MTXL if you're using stock transmitter ?

Hey DDMSteveB, is that kill switch better than the Killer RC super bee kill switch?

Well the only thing that works there is the red led that you switch on and off if the led is on then the motor is on if the LED is off then the motor continues to run

I know its not a killer bee install but i have a question. So, I installed a killer bee on my Baja. I have the RF 45 3 channel receiver and TF 45 transmitter. When i push the 3rd channel button from the transmitter, it shuts off the engine like it should, but when I turn OFF the receiver, the kill switch wont kill the engine, and the only safety measure is the failsafe. Anybody know the solution to my problem? Also, after i installed the kill switch I noticed my engine wasnt running correctly... Its throttle response was garbage, the rpms were dropping very slowly and it had a higer idle than normal, though I didnt touch the screws, and the servo was working fine. Could it be an ignition issue (after reinstalling the coil) or its got nothing to do with the kill switch or the coil reinstall?

Hi Steve, Where can I buy one of those three end hex tools?

I have a dbxl and I have to use a tqi traxxas remote because I got it second hand and I am scared to use it because it ran off twice when the battery died I don't know how to set it up

HOW DO YOU INSTALL A KILL SWITCH ON AN ELECTRIC RC CAR? PLEASE ANSWER🙏🏻

l have done all this & not starting, don"t know why,

Whats the difference between the dynamite and killer bee switch?

Hey I bought a dx5c and I don't know how to program it to work with this

how do i setup the jumpers if i have a 5cell nimh battery?

To anyone that owns one of these.. I installed the kill switch and the red light stays on but If I try to start the engine there is no spark.. If I remove the killswitch cable from the module the engine starts fine but the moment I plugged it in the engine cuts off. The 3rd channel switch works fine I can turn the LED ON and OFF depending on the status of my 3rd channel but it seems even with the RED light on the engine wont start... Again If I remove the killswitch cable the engine will start. If I plug the killswitch cable into the module (Even if the RED Light is ON) the Engine will die immediately. Someone Help? Horizon repair and service dept takes forever to respond.

looks like a RCEXL Optical Large Scale Safety Kill Switch

You showed here how a standard failsave works, but not the killswitch. I kinda wasted my time

its the biggest piece of trash switch of all time... the question isn't even if it will get stuck, but when
