yes, it does it on both sides, but the front is perfectly fine, and yes it with the shocks completely off.

I use the MX-3X as well. It is an excellent control at nearly half the price of some of the higher end models. I've been using it for almost a year now, and have no plans of changing radios anytime soon.

What is the proper gearing for a 3900kv sl 540?

Bit of a update.
pulled diff out again to have another look, found there was shims on drive cup shaffs but on the outer side of diff. by removing them it allowed for another shim to go under the drive pin.
Diff now sounds as smooth as

Pop off the camber link at the wheel hub, so you can see which joint is sticking. Then just whittle or sand it down until it no longer binds.

If it's the ball cups, you can put baby powder in them and work them out on the ball ends untill they unbind. Clean them out when you're happy. Make sure your ball ends aren't screwed so far in that they poke into the ball cavity.

Also check for bent hinge pins.

Check to make sure the antisquat/toe block is squarely seated.

Honestly it's just a process of testing each joint individually until you find the culprit.

Installing my 3300 ready motor into a rustler. Rustler has a 90T spur and the motor has an 18T pinion. Stock pinion/spur setup on sc10 is 18/87. Robinson website said gear ratio for 18/87 is 4.83 and for 18/90 is 5.0. Will 18/90 be lower geared than 18/87? How will temps compare between 18/87 and 18/90. Thanks guys.

Anyone using the JR Mitch setup on their SC10? How do you like it compared to the stock setup?

You might ask someone in the Traxxas thread.

It all depends on the final drive ratio. What is the ratio of the tranny gears? Most likely you'll be fine. Gearing to the moon gets you in trouble.

Also want to note that the brushed version of the Rustler does NOT have bearings but uses bushings so there's more heat build-up there.

Without all the details, you're going to have to do some trial and error. Try it for 2 minutes, temp your truck, 2-3 more minutes etc. Hopefully you have some extra pinions. Good luck!

Can you tell me where are the bushings that you are referring to. I replaced bushings with bearings on the rear wheels. LHS said newer rustlers have metal gears in diff. thanks

Is there a gearing chart?....Right now I'm using stk 18p 87s....

Going to pick up an RC10 TK tonight. I have had a XXX SCT for a bit now and figured I would give the RC10 a try and see if I like it better. Most that I know like it better.
So I guess I'll find out. Can't wait to try and race it.

I got sc10 2wd I put it all together went to the track drove 5-6 laps and I don't like it. It's like brand new


I'm look for a Losi 22t

Sc10 factory kit roller $200

Revtech 17.5 motor 6 laps on it $50

Pm me for me info

Wow, you might want find a Losi 22 to test drive to make sure you like it before dropping another $300

Wow, indeed...

You might want to post that in the for sale thread, not here.
