I disagree on that one....
Kill switch should be mandatory if you are using a cheap or the most expensive radio.....it shuts the engine off..which translates into...no moving 35+lbs $1000+ rc vehicle running away from you with wot hitting someone or something.
The fail safe on your radio is good but not enough for these 1/5 scale cars. There could be a glitch...or throttle/brake servo could fry on wot....or battery could get disconnected somehow....no brakes then....what do you do? Hope nothing bad happens?
At least with the kill switch if there's a glitch or loss of battery or loss of signal or whatever, the engine shuts off. No runaways. IMO it should be the FIRST upgrade you do to your vehicle...even before you break the engine in. Why chance having a runaway and doing serious damage to someone or something? Accidents can and will happen..have the capability to SHUT YOU ENGINE DOWN.
The
Dynamite kill switch is like $30-$40 bucks...Killer Bee/Super bee is around $50-$60. Spend the money for the kill switch.
Here is a good video of a runaway 5th scale rc....no kill switch installed. Luckily no one was hurt. (if you don't wanna sit through the whole thing fast forward to around 4mins)
aaaaand this the explanation of why the failsafe didnt work.
Sorry to hijack your thread voo2doo...back on topic now.
