Any TCS racers have set up tips for Tamiya America Raceway Circuit?

What tire sauce is working best?

I can see swapping to 64 pitch if your running a 25.5 motor on a big track.
You still have to gear for your track no matter what size you go with.
Us 17.5 racers just need a 48 pitch gear. Anyhow thanks for the picture to show us how to use the 64 pitch gears. Im probably gonna use 48 pitch
because the track I'll be racing on will be a small oval type track. I wont need a whole lota speed.

huh?!?!???

you use 64p for a more finer gear adjustments - not because of the size of a track...

I run 64p in all my cars, mod/17.5/USVTA - never heard of someone running 48P in 17.5

if you gear a car with 48 you might get a 4.08 FDR a 37t pinion and a 36T might give you a 3.95 FDR(hypothetical calculation), while with 64P, you could get a 4.05 and a 3.99...a much finer change for a tooth..plus you get get the bigger pinions (55T and up)

and FWIW, EVERY oval racer I know use 64P exclusively whether its indoor or outdoor, apshalt/concrete/carpet

I'm going to rebuild my ball diff pretty soon and when I was at my lhs I picked up Team Losi Racing silicone diff grease/lube 8cc : 22

Will this work really good or should I use something else?

I still have some remaining Tamiya diff grease from the kit and there was a small selection at my lhs just in case you guys recommend something different.

I'm hoping for a perfectly running ball diff and just don't know what diff greases are good

I rebuilt mine recently as well I used the standard tamiya diff lube in
a big tube. Any diff lube should work fine. I also replaced the diff balls
in the rear with tamiya tungsten carbide diff balls.
My rear is smoother than my front. I just didnt have enough for the front.
Eventually I will replace the front with tungsten carbide balls as well.

Thanks, I will look into those diff balls and hopefully get them for my next rebuild. I only run a rear ball diff but might try a front one again soon.

Are you running the one-way or the spool up front?

Zac_with_no_K

I'm running the spool. But I really haven't had enough experience to be able to tell the differences in how it drives.

you'll gain more turn-in with a front diff, but will loose a little 'pull' out of the turns...

the one-way will give you a TON of off-power turn-in as well as loosing braking (since you'll only have RWD brakes), but can carry more speed thru the corners...works great on a WIDE OPEN flowing track

I used to never run a spool - hated the thing, couldn't drive the car...but then I got one with a spool and haven't looked back - now I don't like driving a car with dual diffs

guys, running a v2r and it is dialed. i have a exotek conversion sitting on a shelf but i am afraid to touch the car as i might not get it back to where it is now...sound weird?? question... what will i notice running the exotek compared to the carbon hard tub i run now. surface is high grip smooth set up for rcgt with solaris or xpatterns. Basically...to exotek or not to exotek
thanks

If it aint broke don't fix it.

Personally if the car is dialed for the track I wouldn't change it at all. The only advantage the exotek chassis may give you is making the car a little lighter. I bought my ta05v2 second hand with the exotek chassis and I've had to remove a couple of screws here and there to allow it to "flex" a little bit so it's a little more forgiving through the turns.

I mostly run on a low grip surface, but when I race on a high grip track the car is quick both in corners and direction changes with the same screws left out of the chassis.

You can always try it out for yourself to see if it helps the car to handle better or not, you can always change it back to the tub chassis if you don't like it.

Cheers
Rob.

Thanks... I will give it a shot

The 417 diff won't fit it's a larger diameter.
416 diff will, it's the same as v2 but with metal outdrives
