If you haven't done anything funky on the electronic side (played with boost, esc timing, motor timing, etc.) then I would look to a potential mechanical issue.

Gear mesh too tight is a likely culprit. But binding anywhere in the driveline will also do this. Remove the pinion and make sure that everything rolls freely throughout. Then doublecheck your gear mesh. If everything is ok, and its really only your motor temps (not esc or batt) it might be bad motor bearing(s) or just a plain bad motor.
Ive Checked Gear mesh. pulled motor and diff's move freely. I just talked with Tekin and they are telling me Im geared to low and should be using a 15 to 17 pinion.

I've run two 3660 size 4,600 kv motors (not Tekin, but Tacon and Tenshock) and run 13 and 14 tooth and it was always fine. I would be surprised to learn that going UP in teeth count would rectify your problem.

Curious to know... Can you please report back if it works?

I run the MIP 40 tooth with a 15 tooth pinion with pro 4 4600 and I've never gone above 150.

The roller version is discontinued. The options are now a version 1 RTR or a version 2 in kit form.

Hey guys I'm completly new to the 4x4sc and i just picked upa 1st gen roller to race with. I'm putting a hobby wing setup in it for a power plant and i found a used mip chassis on ebay that i ordered as well. I'll be running it indoor on a pretty smooth clay track any setup tips right away or things i should look at. The rear diff is leaking so ill have to rebuild that right away. I've heard to start with 5-5-3 as a base for diff oils. When i get around to racing ill have to get a good set of tires any recommendations on whats good? I run ions on my2wd stocker but not sure if the 4x4 would tear those to shreds. Thanks in advance

If by 'this thing' you are referring to the bone stock SCTE 1.0, you could check the first page.

If I had to hop it up today, I would, while drinking an IPA (get it? hop...), do the following,

- King Headz center diff mount
- lightened outdrives all the way around
- HD diff cups all around
- cabron fiber shock towers
- chassis

Long term project: Am thinking of eventually converting the truck to 2wd for a bullet-proof 2wd racer (for my young son to race a the local track).

I know I could just hot glue the center diff (and remove the front drive shaft and front diff)... Any thoughts on a possible way to introduce some limited-slip in the center diff to make the car more drivable?

What you plan to power it with? This will be one heck of a heavy 2wd car. Balance will be way off as well.

You could fill the center diff with million to 2.5 million diff oil/grease. and see if that works?

or try the puddy stuff

Super heavy diff fluid should work. Will probably take some trial and error. They make 100k thru 1,000,000 wt. Amain sells up to 500k.

Thanks guys, I figured I could use heavy diff fluid, but didn't realize that such heavy weights were available.

Indeed Casper, this would be a tank of a 2-wd SC truck. It would probably be powered by a 4-pole 540 motor, with EPA throttled down for a young child... I don't think balance will be an issue as much as driving in a straight line without crashing! I figured this will make a great car on which to learn RC driving skills.

It is quite the durable platform. How young are we talking? My son is 7 and has been driving on an off for about 2 years now. He learned mostly bashing around with a Vaterra Glamis. Thing is tough as nails and looks cool. Not quite a track ready car though.
