you just keep telling yourself that my spektrum has never failed :D, moved TO spektrum FROM futaba due to failures as a matter of fact ;)

This kill switch/failsafe debate will go on for ever. I've only had 1 runaway/fault/problem that wasn't handled by the failsafe programmed into the transmitter but can someone answer 1 question - Will a kill switch work if the battery fails, comes unplugged or just goes flat?

There are not many "non user" reasons that a servo would fail, if all the linkages are correctly fitted & maintained and settings on the transmitter are all correct you shouldn't have any issues.
 
good question.. i don't really no, i hope the killswitch works if my batt dies or goes low..

will give killer rc a pm.
 
If not, what is the point of having it? maybe save your back to turn it off? I suppose it might be aimed at people who don't know how to set up a radio or is it one of these "must have's" that everyone jumps on the band wagon with.

The one time I can think of it might be good to have one is if a stick gets stuck in your throttle servo linkage and jams it open at full throttle but would the user beable to switch it off in time and will the kill switch cut the engine at full revs?

Taken from Killer RC website....

The Killer Bee will automatically kill the engine during: radio glitch/loss, low battery, bad connection, or total battery power loss. You can also make the Killer Bee kill the engine anytime you want by pressing the transmitter's 3rd channel switch (Killer Bee v1), or by turning off your transmitter power switch (Killer Bee v2).

So the answer to your question is yes, it will kill your engine. If your running at full chat you can remotely kill the engine by flicking your 3rd channel switch or turning off your radio on 2 channel sets. It will kill at full engine revs as this is how some tuners can see how well their engines are running at full revs, run it full chat and remotely kill then take the plug out to check the colour.
 
The next question is how? if there is no power there, how does it do it?

BTW I'm in no way against these things, I'm just curious to how they work.

yes, if i have no power to my rx i get no spark from the engine thanks to my killer bee V2-s ;)

if there is no power to the system you wont even get any spark to your engine, at least i don't with my killer Bee V2-s. for me to even be able to start my engine i am required to have my spektrum TX/RX turned on. if they are not turned on then my engine will not even spark ;)

As for the engine tuners, surely they have a dyno to give them the results rather than rely on the colour of a spark plug.

Fair point for engine tuners but what about bashers? bashers can check the condition of the engine by plug colour at any engine revs with a kill switch.

I know Kill switches are not a requirement under BRCA rules but in many other nations racers cannot race without one being fitted. Personally having whitnessed a few runaways and nearly being hit by one I would not run without one. At our club it is a rule you have one fitted and it is shown to be in working condition before you can join.

It's not a rule in the BRCA, EFRA or IFMAR that you have to have one and I doubt they would ever make such a rule. It looks like I'll not be visiting you club as I don't have one and probably never will.

Im sure its a normally open switch so it needs power on to close it and make the circuit. If power fails it releases the switch back to the open position and breaks the circuit.

Fair do's Mike, obviously they started out with bashers in mind and an extra safety for running in parks etc. I understand the racing scene is a tighter controlled environment but I think I'm right in saying that in the States and Australia you have to have one to race. Might be wrong on that one though. But I can't see why they would not be considered a good safety feature by BRCA, EFRA or IFMAR.
 
I think it is nice for extra piece of mind. Also being able to turn it off remotely is nice. Sometimes I am very far from my truck and it flips it would be nice to turn it off

Waiting for DDM to get the V1 back in stock
 
for some stupid reason i like the buzzer that goes with it..


so when i kill the engine the buzzer scream's at me..... :lol:

I'm not 100% about the US and Aus but when you're racing at the worlds there the you don't have to have one.
