I have a nitro rush and i recently tore the whole thing odwn and replaced many worn parts as ai bought it used for 30 bucks
I put an os .15 in it, and it runs like a top, but the power of the engine isnt transferring to the rear tires for whatever reason. The car will move, but very slow
I replaced the spur gear originally, so i feel somewhere i messed up something but i ont know what. The clutch bell an spur gear are meshed well, and ive tightened and loosened the nut on the spur gear.
What could be preventing my car from actually moving like it should, right now we are doing maybe 10 miles an hour.
Thanks

Are you sure you put the pins in the axles when you reassembled? If you tightened the nut on the spur gear(slipper clutch tension adjustment), and that didn't help, then you need to look at the next thing. If it's slipping excessively then you should be able to see where it is. Leave the body off and put it on the ground in front of something(like your foot) and give it some gas.
You should be able to see where the power is lost.

prop the truck up on a table so your tires are free to spin. now spin the spur gear, does that spin both rear tires? Both should turn in same direction. Now hold one tire and spin the spur again, only 1 will spin, then try the other side. If only 1 turns, then your pin is missing on that side, if both are fine and everything spins it could be a few things, slipper not tight enough or the cluch shoes arnt grabbn. If neither tire spins, you could be looking a stripped gears, run those few things down b4 rippn it apart, could be just a bad clutch.

I just took my rush out and tried some things,
both tires spin when u turn the spur gear, and each when i hold one and turn it etc.
The wheels spin like crazy when i get on the gas and the car isnt on the ground, its when it touches the ground, the extra friction makes it bog and the car inches along
i adjust the tension as much as i could, i dont knwo what else to do, i took the spur gear off and the clutch shoes appear fine, but then again, i dunno what bad shoes look like.
THanks for continues support

so, with the engine turned off, can you roll it along the ground nicely? coz maybe your brake is conflicting?

Dann

yeah i can roll it on the ground

yeah, try a new set of clutch shoes, sounds like everything is fine from the spur back, that only leaves the bell and shoes. My rush stalled out when the shoes went bad, I suppose they all act just a bit diffrent

If the clutch shoes were slipping that much the clutch bell would be discolored from excessive heat and you would have toasted clutch bell bearings.
Are you sure the slipper is assembled correctly?
Or maybe the diff is slipping.(I don't think it's this, but I'm just tossing out ideas)

Dang, another thing, the spur gear has a metal bushing, is it there? This is a ruff one.

the evo has a gear diff so unless its wasted it isnt slipping.

Right...HPI, I should have known. oops
