Problems
Ok heres my situation. I took my 8ight truggy out 2 days ago with a jr xr2i radio and jr servo for throttle. Everything had gone smoothly the two days before during break in so I was looking forward to tuning. I started it up and ran it down my driveway a few times and the lst time I ran it down I had a runaway!! Thank go no parts broke which is amazing seeing as it hit a tree at almost full throttle. So I took it in and saw that when I turned my car and truck on the throttle had no response. So I took my jr servo out and sent it back to them and I also put in a spektrum dx 2 radio. I thought this for sure would solve my problem but sure enough I took my truggy out tonight and I had another runaway. The strange thing about this one was that the engine didn't go full throttle it just sort of coasted until it came too a stop in the snow. Again no broken parts!!. Now it is really annoying and scary to think everytime you take your truck out it is going to runaway. I am going to get a failsaf but I would like to know what the cause of this problem is. Does anyoone know?

Well on the first run away I lost both, but on the second I really couldnt tell. I am using a pretty beat up battery but I checked the voltage and it was fine. Also how do you access and set the failsafe on the dx2??

Ok I have seen some people put a spring that you wrap around the engine onto the carb do you think that would work? Also wouldn't this put alot of stress on your servo?

I have failsafe, and double up a thin elastic band.. Works a charm!! for me.. last sunday reciever pack died on me throttle was gone. It just sat there slowly ticking over- and not going WOT at a nearby person!
#7
My guess would be the battery. Do you have another one you can try out? if not its never a bad thing to have two anyway.
#8
Ya I think I will buy one.

Any thoughts on the spring around the card or can I just use a rubber band?

This is what I use but the ones I bought from Walmart were clear.

So I shouldnt use the spring but are those just hair scrunchies?

Use the small black rubber bands women use in there hair. A pack of 100 is like 2 bucks. They are petroleum resistant due to that's what goes in women's hair petroleum based products. I change mine every time I service or clean my ride. Who cares if I waste them there like .5 cents a band. I use 2 doubled over around the carb to the throttle pin. I have a thick black zip tie around the base of my slide boot so the rubber bands don't squeeze on the boot.
Oh and not to mention 3-4 around your gas tank works wonders for keeping a good seal on the lid.

It sounds like a switch to me
I had the same problem with my jammin. One second it would be fine, then all of a sudden the truck would take off. I bypassed the switch and I was good. Because even when your battery is getting low on juice it still has enough power to keep the engine at idle. Now when I feel my servos getting sluggish I just bring my truck in and charge the battery. Just my .02

These little elastic band are far better than the rubber bands IMO

Ok with my dx2 do I need a module? I just have the radio and receiver but it seems like I only have a 100 ft of response? Does anyone know if the poer loss is the problem here too? I have no control over the throttle or wheels but my truck just sits and idles? What is a module?
