TraxxasRevolution

Okay, heres the situation...

I just purchased a brand new HPI Savage 25 from a local hobby store. And now I'm having problem running it. The truck starts fine, but then as I tried to break it in, i noticed that the truck moves by itself. Moving by itself so fast that it seems like I'm throttling it 1/4 of the way. Its scary! because the truck doesnt want to stay still.

Any help would greatly appreciated. ThX in advance!

i guess ur idle is to high, i thik u thought of the trim on ur radio right? otherwise u could get a new glowplug and try getting the idle screw right. i dont have a savage, but my tnx had the same kinda problems.

also in relation to checking the idle screw, check to make sure all you other adjustment needles are right, the truck might be 2 lean, is it stalling?

here are a few things to check, when it is running, and you apply brake, if it stops the engine from running fast that means that you just need to adjust the throttle trim on the radio. If it doesnt, I recommend loosening the idle screw until the truck stops moving when it is topped. After you adjust your idle screw, you will need to check that your radio throttle trim is set right too. Hope this helps.

check the idle screw(last thing you shoukd do)
