The "problem" is these ESCs are not provided into the kits by Tamiya Japan (not even the Tamiya-labeled ESCs are). They're all put into the boxes by the distributors, so they can vary quite a bit. Same as the clear plastic wrapping around the kits - not done by Tamiya themselves (yet some collectors seem to insist upon it, so the kit is in "original" condition (which it is not, strictly speaking)... In Europe, or let's say Germany and some surrounding countries, there are still kits that have a Tamiya ESC, some have a Hobbywing 1060 and some have a Carson ESC. So you really need to check what you actually got.

Thanks for that…
I’ve just checked and it comes with a Carson Dragster Brushed 70A which appears to be compatible with LiPo batteries (although it doesn’t say if it has a low voltage cut off).
is this a better controller than the Hobbywing 1060 60A (which I have also now ordered!)?
Are LiPo cells/chargers much of a muchness or are their manufacturers/suppliers to look for/avoid?

What I found:

It looks just like the Hobbywing 1060 (which it says it's rebranded), can't find anything about low voltage cutoff, but if it's rebranded it should.

the 2 jumpers are the settings. One is for forward brake reverse. The seconds for LiPo or Nimh.

Nice

Has anyone tried putting front a-arms/steering knuckles on the rear of their TT-02 (basic kit) to allow adjustable rear TOE? There is a good article about how to do this on THERCRACER.com. Here is a link to this mod...

I realize there are other ways to get rear toe on a TT-02 as I have another chassis with Tamiya aluminum 2.5 rear toe uprights and several TT-02s kits. I just wonder if anyone has any feedback on this mod.

I did it with the TA08 Arms. It works well, just the caster is off. With as small as these cars are, it doesn't really effect anything. It cost less to just buy the 3 deg rear uprights. Car drives just as good if not better without active toe.

I have a couple of TT-02 S kits, one I've been slowly upgrading to a TT-02 SR spec.

I recently purchased Tamiya 42372 RC DOUBLE CARDAN JOINT SHAFTS
39Mm (2Pcs). I should have paid more attention to the TT-02 SR manual as it requires 42mm drive shafts (Tamiya 42339).

The question I have is has anyone tried the 39mm Double Cardan on a Stock TT02 (with steel gearbox joint/outdrive)? I know the Yeah Racing 39mm universal works (I raced with one)

----------

I should note a few things when assembling the Tamiya Double Cardan shafts (42372)
Pro - comes with 1 extra pin & 1 extra axle ring
Pro - included 2 Tamiya 1050 (3mm thick) steel shield bearings
Pro - includes a very detailed instruction manual

Con - did not include any grease (sold separately)
Con - the axle rings can be a bit tricky to install

One thing to note about the axle rings - the included manual shows you the correct direction to install the rings due to the different rotation direction of the left/right sides of the car. I need to show this to a racer at my local track as he was having issues with his drive joints on his TT-02 SRX coming apart. I should also note that the SRX uses 419 a-arms/steering knuckles in the front and uses a 37mm drive shaft (22054) on its double cardan setup.

Make sure to read your manuals before buying parts for your cars!

I’m about to start building a TT-02 with the new Porsche GT3 body for a local “Porsche cup” spec class. It requires the gravity USGT wheels and tires. Has anyone else mounted up these wheels? Will I need extended hex’s or axles to get the wheels flush with the body?
Thanks for any input.

Porsche’s being wide in the rear, usually need a wider hex to make it look right.. but for racing, it might not give you any advantage.

Not 100% sure about the TT-02 Porsche, but I think it does not require wider axles (as I believe the TT-01 Porsche did).

I ran the 2007 911 body in our club ProSpec with USGT tyres and the wheels sat inside. For looks you would need 6 mm to 9 mm hex.

Im not sure of this newer 911 body, but assume for scale reasons that it would be similar

Is this allowed to use in TAMIYA TCS for the GT Pro Spec class?

Yes, but would be better off with the spool or even a putty/ear plug. Tamiya 42247 locks it up pretty good and is probably going to be lighter than that diff locker.

Here are the active rear steering mods. You need Parts bag A, B, Adjustable turn buckle kit X2, 18mm shaft and ballcups ( I used ones from TT-02B shock )
