No grip
Hi everyone,
i’ve recently started racing 1/10 onroad and Im having a blast.
There’s just something that keeps catching me out and I’m not sure if its something I’m doing wrong or what.
The track is asphalt and it gets sugared and cleaned with a blower.
So my last race with my TT02, on practice day I had a ton of grip, I used tyre warmers with goop.
Race day, also tyre warmers and goop but a lot less traction.
I would say both days were more or less the same temperature wise and I was running sweeps 32s which were one race day old from my 21.5.
I did use older team powers on practice though, I do not know the softness.
The race before the same thing happened, I used to use WD40 before I got the goop and tyre warmers, and it was like the car was on ice.
On that practice I used old rush tyres and on race day I tried the same team powers as mentioned above and I quickly switched back to the rush tyres because of the lack of grip - ice…
Admittedly I wasn’t able to apply the tyre warmers for the same duration as on practice because I was running two classes.
My 21.5 looks like it doesn’t have the same grip as the rest of the top 3 but then that could just be my skill level with the 21.5s.
I know its a long post and any advice would be greatly appreciated.

Our indoor asphalt track experienced this a couple times when I started racing there 3 years ago.
Our race director turned on the heat in the morning to get the track warm (since we only race there in the winter) couple of hours before we showed up. Track is coated with a mixture of soda, corn syrup and alcohol. Track had amazing grip in the morning, but the building started to get too hot and the heat was turned off. That's when the humidity level started to go up turning the track into wet sugar then we had no grip (and my tires were coated in sugar which was a pain to scrub off).
Once the humidty levels dropped back down the track was great.

That sounds like something to take in account but, it looked I was the only one affected and no else complained about the lack of grip.
Guys were zooming through corners and my car didn’t even had the straight line grip it had the day before.

SWEEPS are the spec tires for our local asphalt track. They’re good but unglue themselves in Mod. Do you have the part number for the SWEEPS? Could be a carpet spec. Our LHS carries carpet SWEEPS and a new driver bought a set. He had terrible grip and broke his car that day.

IMO not really. They spec motor is so slow that you want to take a nap. 😂 your advance would be in I’m a light weight version of the listed bodies, I think the Mustang and Mercedes have them.!

Thanks! I ended up with a Porsche GT3 and a Ford GT to play with.
Next question, does anyone have a good starting setup for black carpet? It will have oil shocks, oil diff, and either spool or putty diff in front and start out on Jaco Blues.

Even if you wanted to omit it, there is no TCS legal option part that substitutes for those other functions.

Its too bad Tamiya doesn't make an optional blue aluminium or carbon fiber piece to hold down the rear prop shaft bearing and eliminate the rear cover. This would make it easier to tech at TCS events to make sure folks are running the correct pinion and spur gear. Plus it would reduce weight ...LOL

The following link is for an aftermarket piece that replaces the spur gear cover on the TT02. This part IS NOT TCS LEGAL
https://www.thercracer.com/2020/07/t...ear-cover.html
----------
There is no real benefit to removing the spur gear cover on the TT-02 unless you are running classes such as USGT or VTA where small spurs and large pinions are being used with brushless motors.
Here is a link discussing how to modify the stock TT-02 gear cover when racing those classes. Please note that this link discusses using aftermarket parts and the modifications to the spur gear cover IS NOT TCS LEGAL.

Here is a link to a great guide for club racing a TT-02. It shows most? of the available upgrades the chassis. If you have no plans on racing a TT-02 in a TCS race or running in a class that uses TCS Rules, it contains some great info.

FYI: I am not affliated with The RC Racer or that website. However I have found this website very useful when upgrading my TT-02 chassis.
Hope this information helps.
