i need some instructions on how to hook up a failsafe. i have the venom failsafe.

you just have to use the screw to adjust where to set the throttle to if it loses signal, i have the venom, not with the temp thou

ok thanks.

you may want to get a throttle return spring too just for more protection against runaways

whats a throttle return spring and where can i get one for my sv?

Throttle Return Spring Property of misbehavin-rc.com



Anyone who runs a nitro truck is aware of the danger of a runaway. If you run out of range, have near dead batteries in the receiver pack, or in the event you lose power to the receiver completely, the servo will continue to do the last thing you told it. More often than not, it's full speed ahead. This can cause many problems, such as a full speed crash or a blown motor. A throttle return spring will pull the throttle servo back into a safe position when these conditions occur.

Installing a throttle return spring is easy, and well worth the effort required. I chose to use a A-9409 Losi spring, which only costs a few bucks and gives you a spare spring.

All that's required is for you to install two spring brackets and then attach the spring between them. The first bracket installs between the throttle's servo horn and nut that holds the brake lever in place. Make sure you do not tighten the nut back down too tightly. This bracket should swivel easily as the servo horn rotates when moved by the servo.




The other bracket mounts between the shock cap and the front shock tower. You'll want to tighten the screw down tightly in this case to prevent the bracket from moving. The spring attaches between these two brackets.



Despite the benefits of a throttle return spring, it will not protect you from radio interference. So to offer the best protection against a runaway truck, you should also install a failsafe which would cover that circumstance. For more information regarding a failsafe, see my section on Installing a Failsafe.

I've also heard many people mention that installing the throttle return spring on the servo horn in this manner will not protect in the event that the linkage would break or come loose. However in that scenario the throttle return spring that is installed inside the 2.5's carburetor slide boot would come into play. The only situation it would not, would be if only the side of the arm where the throttle return spring was attached to broke, and the rest of the horn was still attached to the servo. That would be a very rare occurrence, in my opinion, but could easily be prevented by installing an aluminum servo horn such as I have done.

can i have a link for spring i want one oh do i have to get fail safe?

http://www2.towerhobbies.com/cgi-bin...?&I=LXUP98&P=7 you dont need a fail safe but if your car goes out of range and you have one, it will apply the brakes and make the car stop instead of going crazy.

yes but this woud slow the car down not break right

the spring would slow the car down, it returns the car back to idle so it will stop

this will do wont it

its always good to have a throttle return spring with a failsafe, if the batteries fly out the elect. failsafe will not work but the spring will slow it down.

thats good

Ok I am a little curious at people suggesting a throttle return spring. From recent experience not even a return spring prevented a runnaway after my venom smart temp spat itself and died. My throttle servo still got stuck on WOT and as such the spring does not return it as the servo locks itself in that position as if you were holding throttle. The Servo wont allow it to return. very interesting. It simply does not do that for me.
Also I do not know if you got the smart temp but if you have, my advice is to take it back & get a new one! Seriously they are not worth the money. Nothing but junk I am affraid to say. The standard throttle failsafes though I have never had an issue with. My smart temp however did not last more than a few months before breaking down completely CAUSING a runnaway situation.
Anyone reading this, you have been warned! By the way, use hump packs in the receiver and you will never have any problems with batteries coming loose. I really wouldn't be using AAs in the receiver if its at all possible.

you might not of have a strong enough throttle return spring mozzy but a trs saves your car if you have a runaway and the failsafe loses power then the trs pulls the servo horn back to idle position and i have heard lots of bad things about venom failsafes too.

so then whats the best failsafe to get, hopefully a small one

anything but venom really i have heard good things about duratrax failsafes
