Default Slasher

I ecently took apart my Traxxas Slash 4x4 from head to toe (clean and familiarize) - have only owned it (brand new) for a month - all looked good, however, the car seems to have a slight grinding sound when pushed manually - but I could not remember if it always sounded like this pr not? Anyway, the only gear that has even remote wear is the spur gear (and only on a small section) - not sure when to replace that? Also, opened and inspected the rear differential - all looked good - however, in the process of cleaning it I removed some of the silicone grease inside - not sure how much is enough in there and/or if I did any future harm by wiping some of it out without replacing any silicone grease before sealing it. I did spray it and the bearings with WD-40 though. Any thoughts? Finally, been contemplating getting a lipo battery and charger. Need advice on what to get with a total budget of @$125. Think I want a 3S lipo 5000mAh and a charger that will charge it as well as capable to quick charge a NiMh battery (8.4V). Any links would be ideal! Thanks to all in advance!

Slashes are noisy, they all sound like blenders full of rocks. You have nothing to worry about.

Now put that $125 toward a gnarly-ass upgraded motor/speedo[8D]

To make matters worse, I thought mine was loud before, then I installed that little 4-pole 1410. I might as well be running nitro now haha

If you want to clean the bearings, remove the shields/seals and blast them out with something like motor cleaner or automotive brake parts cleaner(beware, they both have strong fumes and aren't good to get on skin). After blasting them thoroughly from both sides, allow them to dry and either pack them with grease or oil them, then put the seals back in.
RPM makes a jig to help cleaning.

what good would a gnarly ass motor/speedo do with a NiMh battery that he currently has
From way I read it he wants to buy a lipo, and charger for that cash

for budget stuff you can get http://www.hobbypartz.com/thac6smbachw.html I've read good things on it from people who owned it (never used it myself)
and shop at hobbyking for batteries IMO from owning a slash 3S is not really practical, and only useful for speed runs(and even then the motor will be getting damn hot) I'd start with 2S first you should notice a speed, and run time improvement over the NiMh battery. The 2S 30C 5200mah hardcase turnigy fit in the slash pretty nice just need a bit of foam to stop it from sliding forward. http://hobbyking.com/hobbyking/store...dProduct=14991 you can get 2 with the charger, and still be $25 under the budget

SyCo - those links were super helpful.

My Slash already has the velineon 3500 brushless motor and vxl speed control - what would be a solid upgrade from that?

What pinion gear do folks recommend?

The charger will be fine for him, but those batteries will not hold up long-term in a 4wd SCT.

ITBJHO, the bare minimum for 4wd SCT is the Gens Ace 40C 5000 packs.

I run the Hardcase Turnigys in both my Flux and SLash 4x4, they work just fine.

Running once a month something you've owned for 6 months =/= expert on long-term use

Actually Ive had no problems running Turnigy 40c 2s 5000mAh hardcases in mine, and racing it every weekend will tend to make you pretty good for advice. My equipment takes a beating, and I do puch my truck, so IHHHO they are a good battery.

those are not the 20C 5000 mah's you ran
I run those in a savage flux(along with a slash 4X4, and a Jammin X1 CRT) with no issues last I checked my savage flux(and X1 CRT) is a hell of a lot heavier than the slash, and has a ESC/motor setup rated for 2X the amp draw than the slash.

Default RE: Slasher

the two things that i have found that make my slash 4x4 run noisy ( louder than normal anyway)are the spur and pinion gear being worn and also the center diff or slipper bearing and the rear diff pinion bearing being worn or sloppy. if you run in a lot of loose dust or sandkeep all these items stocked. the aluminum bearing sleave for thecenter diff/slipper is a good buy to. as for the grease if you just wiped it from the housing then you are probly ok but you dontwant to remove any from thering/pinion or the internal spider gears. also i use the 2s 30-40c 5000mah turnigy hardcase batteries from hobby kingaround thehousebut you will have to install your ownplugs. one of those those with theonyx 235 charger/balancer wich i use and have had 0 problems with should be within your budget. i have also been looking at the gens ace batts but have not tried one yet. i like to use the cheap batts around the house and save my good ones for trips to the track.

I prefer the castle 3800 and mmp esc works great, more torque, speed and less heat issues.

Thanks again - that Turnigy 2S 5200mAh is rated at 7.4V (less than my NiMH 8.4V) - will it even be any faster/better??

Fully charged, the lipos will peak at 8.4v for a while but unlike NIMH which slowly discharge from start till the end, Lipo battery chemistry allows the battery to keep pretty much a constant 7.4v output until it dumps. Basically, NIMH gets slower and slower the moment you start driving, Lipo stays constant until it just quits either from low voltage or the LVC cut off to prevent battery damage.

Lipo's also weigh less then nimh, less weight = more speed

Yes, the LiPo will be better because it can supply more amperage than the NiMh battery. When the battery "tops out" the amperage potential from the NiMh battery, it will feel soft.

Thanks - I definitely need some more education on Lipos...

What's the difference between 2S and 3S - between 7.4V, 8.4V, and 11.1V - between 25C, 30C, and 35C

In short, what do these things mean and do - and what do you all advise for my Traxxas 4X4 Slash (speed)?

How about this? http://hobbyking.com/hobbyking/store...Lipo_Pack.html

The battery is fine however the esc and motor will get hotlong before its dead(2s optimal) and the plug shown is wrong. You will need 1 female traxxas plug for battery, assuming that you already have traxxas male plugs on your ecs and charger. That battery will make everything hot, get 2s unless you are prepared to do some major cooling options. Good luck.

That link is for a female Traxxas plug for the battery, correct? Isn't that what I need (I do have a male traxxas plug on my velineon motor and esc. Also, I am concerned that 2S won't be noticably faster than my current 8.4V NiMh - true?
