The motor ups 75C, aprox 167 Farenheit.

I see there is little room to install it.
Which do you use ???
Can you tell me which is the best for this chassis.

There is a pic attached of my chassis.

Thanks !!!
Don't bother, most motors will take up to 100degC now, if your regularly getting a lot higher than that you have set something incorrectly on your ESC or your motor is poo.

if you have space issues then you can use this.
http://www.speedtechrc.com/store/ebp...id=689&id=9848


both are fully adjustable,you can basically position the fan anywhere around the length of the motor. they both come with high rpm fans (15,000+rpm) that are good for cooling 30degF to 40degF cooler compared to no fans.

It looks like they are both out of stock, you can buy them here too. r1wurks.com
These look very nice, altough they are pricey and out of stock!

I have a T-3 with a 48p 84t spur .What pinion should I use on a 10.5 and a 13.5.I just want a safe ratio.I don't want to overheat them.Don't worry asking about what size track we run on.It is so small and goofy I don't think it matters..

thanks. merry xmas!

When in doubt start low say around 6.0 FDR. 84/27x1.9=5.91
Run it for about 2 min. check the temp and go from there.

I was very happy with 84/26 with a 13t on a goofy track.
Rubber tires right?

Default Titainium Pivot Pins

Anybody know where I can get Titainium Pivot / Hinge Pins for the T3. Been looking but can't seem to find any after-market ones for the T3.

thanks

For anyone running the Spec R diff, what would be a decent oil to try as a starting point running in the 17.5 class. Also what are the noticable differences over the ball diff?

Default Steering

Stillbill I wouldn't be worried about the steering it works great. I would update the car to a 2011 specs if your buying a chassis the new car is dialed.

It depends on the level of traction, I run on a low traction carpet track and find 3000wt to work quite well. If you are running on a high bite track start with 1000wt and go up or down from there. The only difference I can fell with the gear diff is that seems to remain some what more consistent over the race day. The only down side is the Spec R tends to leak a bit with thinner than 1000wt lube. I'm hoping Xray will come out with a gear diff soon for the T3...hint...hint

Default bearings

Are the bearings in the T3 the same as the T3R?

I would start at 1000cSt and try it.

We have found that coming off power it can sometimes make the back end kick a little. This is particularly bad on a track with a lot of sharp corners that are approached at high speed.
This all depends on the size or track and grip levels etc.

If you find the back end a bit loose, try the ball diff with no other changes and see how it feels.

+1 at the moment have been happy with the ball diff which suits our track conditions .....but now that i have the new gaskets, shims and o-rings am going back to trying the geardiff using 1000....which is what i was using oh and prepping the track helps....thats when the geardiff comes into its own...
