my hpi savage x 4.6 idles but wont move

[darryl1980]

whatg would cause it to not move forward when i press the gas on my controller?

Well there could be several things. First check the slipper clutch on the spur gear. Make sure the pads haven't worn out tighten all the way down and then back it off 1/4 turn. Next check your driveshafts front and rear make sure the grub screws havent fallen out which tends to happen. After that make sure your tires are glued to the rims. If all that's good then it's time to get the wrenches out and crack open the transmission. I'm sure someone else will chime in with something that i have forgot or can't think of at the moment. But we'll get you going

Will it move the wheels if you hold it off the ground and hit the throttle?

 

[ChiefGeek]

Is it reving, dieing, or just not responding to throttle? Does steering respond?

Knowing the Savage 4.6, I would say the most likely cause is your spur gear is knackered !

Should look like this :

But probably looks like this :

Or something along that line. If you look at the teeth to see if they are melted or broken up

If slipper is set to loose you will have that problem. Happened to me once.
