That is a rite of passage for any beginner, searching for a lost dog bone, and having some eagle eye veteran spot it across the track from the pits.

what is wrong with my car?!
 

Help! I have a Tamiya tt02 drift conversion (4wd) and it will only drift to one side, it turns both ways evenly but won't drift on one side but still drifts perfectly on the other.

Have you done all the basic troubleshooting? Suspension setup is the same side to side? Drivetrain is free, no binding, particularly at one corner? Radio trim and end points are set correctly?

Yes, this is a new problem, it was functioning fine earlier this week.

I have a tt02 and i don't understand why a bitty design 190mm porsche boy is to wide for the car?? Is this normal for the tt02 to only have tamiya bodies use on this chassis

It all depends on the parts you used while building the car. There are steps specified in the instructions and components that serve to widen the track depending on the body to be used.
There are also longer outdrive axles and hex’s available to move the wheels out to full width.

thanks

I’ll check it out

Which smaller spur gears fit the TT02's 4 hole bolt pattern? Looking for low 70T spurs to get USGT and VTA gearing.

Ive been looking at the manual it looks like the disc brakes is a plastic piece that makes the car wider. Seems to be the only part. is that it or am i missing something else?

The wider plastic hex/disc when used with the stock axles, you'll find you dont have enough thread to mount your wheels. Tamiya sells a TT02 parts tree that includes the wider axles. However, only one is included per pack. I had a friend confirm that the TT01 axles work, and they sell a pack that includes two of the longer axles.

Yes, this is the stock solution.

The other way, that I have on a few of my cars is some TG-10 axles, with wide hex hubs like these.

I just milled down the like 15mm hexes that come with the car, they hold the pin tight so no issues when you take the wheels off anymore.

Found my issue. Thanks.

Posting this in case the info helps someone.

There are two "versions" of the #54558 Tamiya TT-02 Aluminum Motor Mount.

The version of the #58558 Aluminum Motor Mount that is available as a separate hop up part has 5 attachment positions per side labeled for pinions 16T-25T.

The version of the #58558 Aluminum Motor Mount that comes included with the TT-02R and TT-02RR kits also has 5 attachment positions per side, but its labeled for pinions 18T-27T when using the included high speed gear set 68T spur. It’s also machined slightly differently.

The version of the mount that comes with the R/RR kits isn’t available separately (as far as I can tell). I just happened to notice the difference when I was swapping motors between my regular TT-02 and my TT-02R (built without the highspeed gear set since its not allowed in our club’s TT-02 class).

Not sure why Tamiya chose to use the same part number, but if you have TT-02R (or RR) kit that you run with the standard 70T spur, make sure you ignore the labels on the mount and pay attention to the A-K labels on the Motor & Gear chart in the manual.
