please help, when i thottle my hpi rush evo the engine splutters dies, ive tried tuning it doesnt help and it will run for ever when idling it just wont go. nothing appears jammed. im thinking it might be the clutch but im new to rc cars and cant sort the problem.

When the bottom coil on your glow-plug goes bad the engine will usually idle but then just die. If you remove the the plug and check it, the entire coil must glow, every coil..... And if you are unsure, replace it.


Try a new plug.

will do, thanks.

I got a rush evo, took it to the track for the first time, hit a tractor, broke a few pieces and it was still running strong.
As the night wore on, it got to hot, (330) I put the piston on the down stoke, bottom, replaces the plug, now today, it runs ok, but the top end isnt were it should be. Ive tried tuning the carb to make it run a bit better on top end, but its just off still.
Could the servo for the gas be off a bit? Or could the new glow plug be bad? Any tips I should try?
Thanks for the help...

You might have lost some compression when you ran it at 330. High temps = bad things.

Jeez...330 is not THAT bad....

welp, it runs fine now, or did[>:]. HPI went cheap on me, or on all the rush evo trucks. I fried the grears in the rear in. Come to find out that there wasnt jack (you know the word) in the gear box, well, very little. It got hot and now I have new gears.
I also got new shocks and carbon fiber shock towers, front and rear. Went with a bigger bell housing, 15T and a chevy body for it, now I need gas, broke after all that.
Just check out your rear end for grease, if it came as a RTR truck anyhow. Just hoping Im the only one who has had this prob. Also the hpi web site has tons of hop ups, just need to go to the europian site, not us site.

Took apart my diff a few weeks back to replace the spider gears there wasnt much grease back there on mine either, Kinda figured there didnt have to be much so i only threw in a little bit, havent had any problem sense, should it be packed with grease?

yes it should.

try replaceing the fuel line it might have a crack in it if not it sownds like a tunning prob
hope this helps

got my new gears, packed it with grease and it runs very sluggish on the take offs, like its dragging a 10lbs weight behind it. I took the rear end apart and took out some of the grease I put in and it zips right along now.
I bought grease at wally world for 3 bucks, extreme pressure multi-duty grease (some lithium based stuff) and it should now go forever, well the gears in the rear.
