I never had a Kill Switch on my Baja and only ever heard of people having runaways, getting the MCD I asked about a Kill Switch as I was looking at bashing and racing and was told no one runs a kill switch on the track. One of the issues with the Baja is that the throttle linkage runs very close to the engine and tank and the theory was that when bashing just a small stone/piece of debris could lodge itself between the linkage/wire and the engine/tank and cause the servo to fail. Looking at the MCD models they run a fairly tightly enclosed internals with the pan and body overlapping and have plenty of room for linkages etc. so I am running without..... I may regret this but.

On the race track only a few run with an on/off switch as this can jolt and switch things off.

You have misunderstood the need for a killswitch. Jammed linkage is only one possible problem which a killswitch allows for. It will also save you from a runaway if
Your transmitter stops sending signals
Your receiver stops receiving (could be crash damage, loss of aerial exceeding range, flat battery, damaged switch, lost battery (physically) shorted wires
Jammed linkage

I would be totally amazed if people running races don't see the benefits of fitting a killswitch. At the bigger tracks in Australia, a killswitch is mandatory

Managing without one increases risks that you will have a problem which could be serious depending on what or who your runaway hits.

Hi Tony, I understand the reasons for having a kill switch I was merely relaying what I was told by Rik at Rossendale models when I enquired about having one fitted. I was told that neither Rik or Stevo both of whom race MCD V4's, I think Stevo is leading the championship, have them fitted nor an on/off switch and neither do any of the other guys as far as they know. Seems strange to me but there you go.
 
i think why not fit a kill switch, for about £20 you,v got peace of mind, if your running in a public park and you have a runaway your buggy could hit a kid, been in that situation myself and i was lucky the kid was ok,

I got the same advise from them. They said they were more trouble than they were worth but I suppose racing is a more controlled environment so damage / injury is minimised anyway.
 
I guess there is no law preventing ignorant people from working in model shops. It is a real shame that they could be increasing the risks their customers face because of their flawed opinions. Maybe you should point them at this thread...
 
i've spoke to the guys at rossmod myself with the same advise but untill you have a runaway yourself then you would probably take the advice from the guys that race these things but as andy says stevo and rik both race and there are marshals and barriers to stop that kind of thing but in open/public parks they are a must because when these cars take off specially on full throttle as mine did, its scary cause theres no stoppin them untill they hit somethin and beleive me the mark mine left in the wall and the damage to the car i will never run without one again!!!

Trebor, I repeat, the absence of a killswitch has NOTHING TO DO WITH THE QUALITY OF THE RADIO. You may well be right about the KM radio, but please stop confusing unrelated issues.

Yes, you were suggesting the the real problem was the radio
i think its just gonna be the crap radio in your KM that you will have
trouble with..........not sure if the servos are dodgy

And I was pointing out that your answer doesn't address his problem because a killswitch has nothing to do with the quality of the radio....

rory's original concern was hearing of runaways with the KM ........i addressed that with the poor quality of the radio /servo.......i never mentioned kill switches but i do have peco switches fitted to a couple of my MCD's........but don't run poor quality radio just in case as kill switches arnt get out of jail free cards:lol::lol:

+1 Trebor. Correct me if Im wrong but this thread is questioning KM runaways so Trebor has a valid point if the crappy KM radio and servos contribute to this. Voo had a killswitch fitted to his KM but the apparently invalid point about crappy KM radios would have been good advise then because the sh1te KM radio failed to operate the killswitch when it was needed. If it wasnt for the crappy KM radio, he wouldnt have had the runaway in the first place.
