Maybe a soon-to-be-released TT-03?

Kit numbers that start with a 4 or 8, are limited editions and eventually are marked discontinued. Eventually Tamiya will release a new version.

Tamiya has been releasing many TT02's on a regular basis for years ...this year they came out with a handful of new TT02's as well, ..Tamiya hasn't stopped releasing or supporting the TT02 platform.

Here is my progress on my TT02sr project. This car has the Yeah Racing shocks & adjustable motor mount.

TT02 can’t drive straight
 

Hi everyone, this is my first post apologies for the length of it. I’ve been racing for many years but only with my tt02 for approx 4yrs, my friends tt02 after 6 months randomly started pulling very badly and spinning by itself which he was never able to rectify to the point he gave it away and moved to blinky class, last weekend in the middle of a race mine started doing the exact same thing? It’s not torque steer or anything obvious, I’ve completely stripped car and changed all bearings. It just seems strange it’s exactly the same fault as his and seems to be a tt02 thing, the car has lost all grip it’s literally like driving on ice. Has anyone come across this before? Any help would be appreciated. Many thanks

I would suggest taking the stock diffs apart and checking for any debris or damage. I recently found a broken tooth on a plastic diff gear on the used TT02 I've been rebuilding. These are plastic parts that can wear out over time.

Tamiya 54875 TT-02 oil filled gear diffs do come with metal gears inside the diff housing, but still use plastic gears on the outside ring and pinion gears.

Hello everyone. I picked up Tamiya's Mustang GT4 kit and recreated the Volt Racing Mustang GT4 from 2018. I'm still working on the paint and livery but I also have questions about drivetrain options as well.

Most of the information I've researched online about drivetrains is about getting top speed and power out of their car. Personally, I just want it a little bit quicker and faster than stock. With that in mind I went with Tamiya's 17.5T brushless, along with Tamiya's high speed gear set #54500. I THINK it's faster than the torque tuned motor that originally came with the car, but im not sure. What do you folks recommend to make this car a little quicker and faster than stock?

Again im not trying to break any speed records. I'm still running the stock TBLE 02 ESC. Other mods are the tamiya aluminum driveshaft, propeller joints, oil filled shocks. I'm also running a Venom 2S 5K lipo battery. Thanks in advance...

If you want to go faster, you need to shift into higher gear. Same thing as with your 1:1 car.
If you take a look into the high speed Gear Set manual, you will see a choice of different final drive ratios. The lower the ratio, the higher your top speed.
With the Tamiya 17.5t brushless motor you can easily choose the lowest ratio shown. I think it is 64:29 ( spur gear : pinion).
64 t spur gear: Tamiya # 51536
29t pinion: Tamiya # 54229
With a bit of luck and fully loaded battery you can reach 25mph (40km/h) with this set up. If this is still not enough there are other ways to optimize the TT-02 's final drive ratio for even more top speed.

And just like the 1:1 car I have to decide if I want more top end or better acceleration. If I wanted better acceleration, then installing the high speed gear set was a mistake, correct? Since the stock spur was a 70t and the spur in the high speed set is a 68t? Thanks again...

Correct, for acceleration a 72 spur or a smaller pinion gear would've worked.

Not that the spur gear alone makes that much of difference. With the standard 70t spur gear and the max. 25t pinion, your max. FDR is still limited to 7.28 - which is very short (unless you were planning to put a modified motor into that car - which I would not advise). The speed spur gear set has the advantage, that it allows a wider range of standard spur gears (even non-Tamiya) to be mounted, so that was a very good option part to get and install.

Ok then. Thinking about how the car is used, its mostly in parking lots that don't have a lot of room to get up to speed, so I'm thinking about being geared more toward acceleration...I think. How low of a pinion should I try? Or is this when trial and error comes into play? Also, should I be looking at another ESC? I read that the TBLE 02 isn't all that great. How about the motor? Maybe I should've gone with the 15.5T Tamiya?

The 17.5 brushless does have a lot of torque, that allows you to choose a longer final drive ratio for top speed AND acceleration.
You can have final driive ratios of about 4.0 (or even less) and the Tamiya 17.5 still produces a decent acceleration.
I am strongly recommending the 64:29 gearing as a starting point!

Ok ill give that a shot. Can I just keep the 68 spur and go with a 31t pinion to get that 2.2 FDR?

68 and 31 will give you 5.7 (internal ratio is 2.6). To gain full flexibility with spurs and pinions you also need the Yeah Racing motor mount.
