Arrma vendetta possible wheel drive issue

[CrHardSniper]

Hi, Just today i've fitter a rocket rc 36 series brushless motor in my 3s arrma vendetta but after running it about 1 minute, it sounds like my 26 pinion gear is spinning while the slipper clutch isn't.
edit: i've taken the motor out and ran it and works fine, fitted it back in the car and when i lift it up its still fine but when i put it on the ground it makes a weird noise and barely moves forward

help is appreciated

Probably striped the plastic spur gear inside. Going to need to open up the power module and check on it. You may have not set the mesh quite right or something else. An option you have is to buy a steel spur or get more plastic ones.

Tnx for the respond but i've already opened it and nothing seems to be damaged

Is the screw inside the slipper adjusted correctly? If it is too loose then the slipper will just slip instead of moving the car

Looks like you're in good hands here. Welcome to AF!! Great to have you aboard

 

[CrHardSniper]

I don't see a screw in the slipper
What I do see is that my spring is slightly scratched but that should be no problem

 

[Moonstonemike]

Yeah from your picture I don't see the screw either. It's supposed to run through your slipper.

well that's weírd
the slipper does move back and forward a little
i ran the motor outside the car and it worked just fine but when I put it inside the car it has that same issue

You need the screw in the slipper otherwise it doesn't function at all. So you need to order one for it, the screw is your adjustment for how much the slipper slips. and if you don't have a screw that means it wont engage at all and therefore wont move the vehicle at all. Other option is the buy the hot racing spool which I am running and love it very much

Mesh looks a little tight, and it looks like you may have the wrong size pinion, do u remember which one u bought, just guessing at this point!?

I think the screw is on the slipper shaft now with the lil spring.. in the vendetta

from the box it comes with the default pinion gear (20 teeth) and a 26 teeth pinion gear

 

[Moonstonemike]

Do you see this screw over the spring?

 

[CrHardSniper]

No, the Vendetta has a clutch with a nut on the shaft, as shown below:


I think the slipper pad is gone. I removed the slipper clutch assembly and even with the nut tightened, I can spin the metal cap independently of the spur gear.

Whoops forgot they changed it on that one. Good call

Vendetta/infraction spurs are more like the mega spur. Did you check to see if the large red plastic nut is tight? That’s what keeps it togethor. I’d take pics but just had surgery…
Part no. Ending in 808, make sure it’s tight. That goofy red tool they include helps with that then let us know if worked.

Should be visible opposite the side with the red aluminum connector. Just has 1 pad.
Part ending 0944 above is the slipper pad.
You should post pictures of your spur honestly. Probably easier that way…

Ohhh, like the mega. I did not know that!!

Nut was set to factory default when the issue happened, 12.2mm from the edge of the shaft. Tightening it down to 13.5mm from the edge didn't help, still no grip, metal cap spins independently of the spur gear. Will post pictures tomorrow of the spur and pad.

As promised, pad is slick as plastic:

I would clean both sides of the slipper pad with some fine sandpaper and clean the metal drive cup that contacts the slipper pad. Then reassemble and tighten the nut so the spring is almost completely collapsed.
