I just bought my truggy a couple weeks ago it is an hpi truggy. I did the proper break in according to hpi and had no problems with it up until yesterday the truck won't stay running I reset everything back to factory settings and still the same problem. The truck will shut off when I hit the brakes only when it's driving tho. If it is at idle and I hit the brakes it stays on. I have messed with the idle screw and also the brakes and nothing seems to work. Any suggestion?

You said it stalls when you apply the breaks when it's moving but not when stationary. How long does the engine run for when the car is stationary?

When it's just sitting there it will run the whole tank with out shutting off

1) With the car sitting turned on and engine running, idling normally (no control input), turn the idle screw IN until the revs start to climb. As soon as that happens, back it out again just a touch so the engine goes back to idle. Leave it there.
2) Test again. If when braking after a WOT run, the car stalls, turn the low speed needle in 1/4 turn and repeat the test. I doubt you will need to do this more than once, if you do this twice and you still have an issue don't do it a third time, come back and let us know what happened.
