I'm not a racer, so my knowledge is maybe not 100% correct.
Here in Germany we have the Tamiya Euro Cup. According to the 2019/2020 reglement Its stock class is box TT-02 chassis with minimal upgrades, only CVA dampers, ball bearings, front CVD and low friction suspension balls and low friction screws are allowed. They are running Tamiya bodies, Tamiya tires, Tamiya ESC, hand out motors, and even NiMH batteries. Only 70t spur gears and max. 23 t pinion can be used.
Other classes as Top stock ("all-in" TT-01 and 02") or Euro TW (all Tamiya TC chassis but no TRF ones) are also run.

Stock ESC (TBLE-02S or TBLE-04) calls out for either sensored 2pole 540 size brushless motors or brushed motors.
The Hobbywing 4000kV you linked is 4 pole sensorless and will not work with Stock ESC.

If you want to keep Hobbywing choose one of their Justock G2.1 motors, they are a great match for TT-02 and stock ESC. Maybe you have to install a ESC fan, when ESC is getting too hot. Tamiya TFU-01 (45063) can be used for TBLE-02S and others.

Thank you and jgil089 for the reply!

Made my decision and will stick to the HW Combo since I can get a good price for it. Will save the TBLE-02S as a space for my DT03.

I will also get a set of Yeah racing aluminum dampers 55mm. Yaay, can't wait to get started.

13,5T not that I know of. But apart from the Tamiya Euro Cup there‘s a series called RCK Kleinserie running all available TT-01 and TT-02 kits with 17,5 T motors.

Hi Raman,

My CVAs finally showed up, i was in the process of installing them when i noticed (and i dont know how i never noticed before) that the rear hubs have a travel limiter. I realised the rear has zero droop.
Is this limiter normally removed?

Post a picture of these limiters

sorry for the delay.

These are the limiters, depending on if you have it set high or low. They contact the lower arm at droop/when load is off the wheels.
In my case the were in contact at normal ride height.





I ended up cutting the bottom ones off. now with CVAs and 1mm front and 2mm rear droop it feels better on the driveway. I have to wait until our current lockdown ends to see if its better at the track.

New guy. Learned a lot here so thanks to all.

Question: I use 48P Kimbrough Spurs in my TT-02. In order to mount them to the alloy hub from the HS Gear Kit, since only two tapped holes line up with the Kimbrough Pattern I've had to transfer/locate, drill, and tap two additional holes in the Hub. This works fine but is a huge pain in the neck. Do you Kimbrough folks modify your hub or just fasten the spur with two screws only? I feel like I must be missing something!

2 mount holes is more than enough.

I'm a novice when it comes to road cars so I'll certainly take your advice to heart.

Is that really what all the Robinson guys do? Just mount with 2 screws? I'd think 4 would better distribute the load and be less prone to distorting the gear.

Waddya think?

its very common. Not just with Robinson racing, but most non Tamiya gears. I use Zenon or Panaracer on my TA05, TA08 all which. I use for racing, all spurs are mounted with 2 screws.

2 is more than enough, have no worries 😉

I disagree. Just a bit... and and not seriously. Let's just say, two screws are enough. Period. See, in my twisted little brain, two being "more than enough" could be interpreted as even one is enough (since two are more than enough.. and two is more than one... and although I have never tried it, I'd say one is not enough.
Sorry, just had to tickle my funny bone there, Raman. But on the issue here: fixing a spur with two screws is absolutely and definitely enough on the TT-02.

Hi Raman,

These are the limiters on mine. are they not on all variants of the TT02?

First, I've been on RC Tech for over 2.5 years, and originally got involved in RC over 35 years ago. Second...and more importantly (not to mention, more appropriate to this thread)...I just acquired two TT-02 kits...one for me, and one for my step-dad. While my Step-dad does have two other RCs (2WD Traxxas Slash, ProBoat Recoil 17), he has never built a kit. The TT-02 will be his first kit. However, instead of just getting a kit for him to build, I thought it would be fun for us to build our own, separate, kits side-by-side. Although, in typical 'Black Cat' fashion, both will have a few upgraded parts right off the bat (oil-filled shocks, bearings, and some other goodies). Mine, however, will be upgraded considerably more than his, as I have secondary plans for mine - racing. I've already acquired most of what I'll need (including the High-Speed Gear Set), while other parts are either on their way, or will be ordered soon. HOwever, there are two things I could GREATLY use some assistance on.

First, starting with the aforementioned High-Speed Gear Set, I know there are other-branded spur gears that will fit the spur adapter...but, I do not know which. I know the stock spur is .6Mod, but I'd prefer to go with 48P. What quality...and, I do want to emphasize 'quality'...48P spur gears will fit the High-Speed Spur adapter? Associated? Kimbrough? Others? Second has to do with an 'alternate' parts upgrade route I am considering, namely the Yeah Racing TATT-S04 Competition Touring Car Upgrade Kit. Is this a good/smart idea? Or, should it be avoided? I know that most parts from Yeah Racing are quite good...but, I also know some of their stuff is "just ok", and some should be left alone. I'm not concerned with the price...just the quality, and length of usability. An input would be appreciated.

No, not on the type S. I think those limit the movement to stop the dog bones from popping out. They’re not for droop. For droop you would place inserts inside the shocks, eg 1mm spacers, 2 mm spacers. A royal PITA but that’s the TT02 suspension lol.
