Hey guys,

Today while running my buggy, I completely lost radio control, and the throttle stuck where it was when I lost control. The thing went barrel ass right into a busy road, but fortunately it didn't get smushed.

Anyways, it seemed to go back to normal after that. I drove it slowly for a little while. Then it happened again. I lost control and the thing just went straight and I had to chase after it. It was moving much slower this time =)

Anyways, after it happened yet another time, I disconnected the fail safe. After that, I ran for 45 minutes without trouble.

Do you think it was coincidence, or that the radio may be failing? Or have you seen this before?

It's a venom failsafe.
 
Had exactley the same thing with my Dynamite failsafe. Instead of applying brake, it would open the throttle. I though my rcvr was messed up but my steering was always fine, just the throttle brake was screwed up. I reset the failsafe per instructions and headed back out only to experience the same thing. I did as you have and removed it altogether and things have been fine. With no problems since removing it, I feel that my rcvr is fine and that the failsafe has just gone bad.
 
I have the Dymanite failsafe and have had similiar problems... because of water. Mine has gotten a little wet twice, but once I dried it out, it worked fine. Maybe you could take your failsafe apart and see if there's any debris or anything in there.
 
Hmm, yea that is a possibility. I will take a look. I'll also check out the reciever.

Speaking of recievers, if it is busted, anyone have a good place to get a normal JR FM reciever for a decent price?
 
I still think the best solution is to NOT run one full stop. Don't you guys see, it's just ANOTHER thing to go wrong.

Set up you're radio gear really neatly, ziptie everything down, and keep the batteries in check - hell even run a battery meter if you need to (a throttle return spring would do the trick too?)

...and you won't ever need a failsafe. I've been fine for the last 5 years or whatever, no failsafe, just trusty radio gear and everything set up neat and clean.

Smart man. Failsafes give people a false sense of security.
 
Again with this poop.

It doesn't give anyone a FALSE sense of security. It give them a sense of 'if the radio signal operations fail in any way my ride will stop' sense of security.

Twice in the past 2 years I have had vehicles take off on me without a failsafe on them. The throttle return spring didnt do poop to overpower my servo. Yeah, both times were my fault in that I didnt have the transmitter on, BUT, had I had a failsafe installed at the time, it never would have happened at all.

Say what you will about failsafes in a negative way, but as far as I will EVER be concerned, you should run with BOTH a failsafe AND a throttle return spring.

It just makes sense.

Sure, you could run with one, or the other, or neither, but both is what I think to be the best.

Hmmmm Christian ya like failsafes there buddy???
I have two of them waiting to be installed. I played around with them a little bit and it seemed it would lock up and just not work at all.
 
I have just installed my first fail safe and I set it to apply slight brakes if it gets a conflicting signal. I use it with a throttle return spring that will pull a dead servo with no problem. I have used the TRS on other nitros for a few years now and actually used it once (got too far away with weak batteries).
I feel that the use of both is a cheap insurance policy against most mishaps, especially since I now have a $2000 plus buggy.
 
Well, I'm gun shy now regarding fail safes. I put one in because of a loose battery in the stock battery holder causing it to take off and subsequentially, over reving the engine and blowing it up.
I will admit, the fail safe did give me a sense of security. I would drive around not worrying about signal loss, dead batteries or whatever. I had a fail safe, what could happen ? Well, the fail safe is what could happen. It malfunctioned and did just the opposite. It decided to open the throttle instead of closing it.
And someone said it before, a failsafe is just one more thing in the chain that could go wrong. I'm not knocking them, but like I said, mine went bad and now I'm a little nervous using one again in fear that it too might fail. Until mine went squirelly, I was a big supporter of them. It's the Rush Limbaugh saying, "We agree to disagree". How supportive would you be if something you depended on let you down ? Bottom line is batteries can die, fail safes malfunction, throttle return springs break or disconnect. We can either add a crap ton of checks and balances to our machines in hopes that something will catch the problem, or we can eliminate as many pitfalls and keep things simple. Me........I'm going for the string around the ankle tied to the wing method.

Alright already! Whatever you say! I'm a rabbit!
 
Failsafes don't make sense if they are prone to fail and cause a run-away. I have experienced this with a dynamite servo-saver. I am considering getting a return spring and adding a radio gear check to my setup routine.
 
Had the Same Problem

I had the same problem but had the Ofna Micro Fail Safe. I reset the unit, applyed the brakes then hit the "set" button and set the fail safe. I test if it works by turning off the radio and see if it applies the brakes. It did.
 
Failsafes aren't prone to failure, but of course it does happen every now and then. The only reason mine failed was because I was running right after some hard rainfall and it got wet, but that's my fault. My failsafe has saved me a few times and for $30, it is well worth the investment.

Saying you shouldn't run a failsafe is like saying you shouldn't have an airbag in your car as long as you buckle up and drive safely. I will keep my airbag.

Well i've ran two different kinds of failsafes. Both have worked great. The only time I had problems was when I was running in the rain. The failsafe got water in it. But I pulled it apart and dried it out with a hairdryer...and it still works.

I'm surprised people have had such bad experiences with failsafes.

cbreaker, i'm using both a dynamite failsafe (which has a button to set it) and a ko-propo (which has a set screw for adjusting it)

I think the ko one is probably better.
 
i had a problem with my venom fail safe i whould run for about a half hour then i whould lose signal.pause.then whould come back. iam running with a hpi 1200 mah hump pack at a full charge. so i took it out and havent had a problem yet...for sale 1 venom fail safe...
 
can't you guys who suspect broken fail safes leave your rx on and turn off your tx? I test my fail safe everytime I turn my car on.

i do or did check mine every time but when my hump pack ran for like half of a tank it whould stop responeding.imo venom fail safe is a pos
 
Thats horrible that all of you have had bad experiences with fail safes.

Fail safes failing is another sign that the world is coming to an end.
