Alright even better than I expected. Thanks!

hi,
I use the Tamiya Hop Up battery plate 54555 (transponder stay included).

Is there a blue hex screw set available for the TT02? Doesn't have to be Tamiya, actually price wise definitely doesn't need to be Tamiya :).

Or is there a place to get colored anodized screw hardware in bulk anywhere?

Ebay is where I get my aluminum hardware.

I get mine at amazon

Hi everybody,
Does someone has the possibility to post a copy of the manual of the TT-02 S Aluminum upper arm mount set? This is hop-up # 54651.
I couldn't find a manual online.
Thank you!

Cool, thank you Markus!

So I got the 1st or 2 kits built last weekend with my son.

I thought the stock friction sticks would be ok. I was wrong! Ordered some Yeah Racing replacements. The bearing were definitely a good choice. Also put an order in for a better pinion gear as it was advised the stock ones are a tad soft.

Keeping things as stock as possible for budget reasons. Staying with a 21.5 motor and going with Hobbywing budget ESC.

Overall I really like the build of these kits. Little nicer than the TA-01 I helped my dad build almost 30 years ago. And yes, I still have it.

It is commonly admitted that 13.5 is also stock... Then it will also depends on the timing, blinky or boosted.

“stock” = controlled wind and controlled electronic timing (no boost) is the commonly held view.

super stock, stock, pro stock, sports stock - all deviations on a theme.

mod means no limits (Well, can size and rotor size have absolute limits). Boost, timing, winds - up to you.

This car is working very well for me in VTA now. I got the setup down and found that I needed to add limiters inside the shocks to change the droop on the car. Once I did that the car got a heck of a lot better .

Does anyone know if the steering knuckles and rear hubs from TT01 can also work on TT02? Besides the small difference that TT01 uses 5x11 instead of 5x10 bearings for the wheel axles, are the parts interchangeable?

You on black carpet? Can you share your setup? Tried running mine the other day and pulled off after 2 laps car felt like it was on ice. Think the aluminum steering might be a must

New to RC and haven't even received our TT-02 kit yet. Does the following look like a good choice for a servo and is 120deg enough? It is a JX PDI-6208MG

Dead zone: 2μs
Maximum pulse width: 900-2100us (suitable for remote control)
Maximum angle: 120°
Motor: iron core
Working voltage: DC4.8~6.0 V
Speed (4.8V): 0.09 sec/60°
Speed (6.0V): 0.07 sec/60°
Torque (4.8V): 6.8 kg.cm
Torque (6.0V): 8.2 kg.cm
Size: 40.5X20.2X38mm
Weight: 55.6 g
Bearing: 2BB
Cable: JR 265 mm
Output teeth: 25T (Futaba universal)

Car is dialed...running on outdoor asphalt...35wt oil ft and rear. 1.5mm shim inside shocks f+r. shocks all the way in on front and all the way out on rear. HPI tires front and rear...Vintage tires...5.5 ride ht front ...5.0 in the rear. Calms car down...Added the 3Racing oilfilled diff in the rear with 1000wt oil and a 3racing spool in the front. PF mustang body.....I use Savox servos. 1251mg ..59.00 from the bay and fast and strong.....Also use the yeah racing adjustable motor mount, the one with the slots not the holes and usa a 82 t spur and a 51 t pinion in 64p. 6mm hub in rear 5mm hub in ft....1.5mm toe out on front 3 deg toe in alum hub on rear. :nod:

The sweep - 120deg - isn’t really that unusual for an entry level (and some expensive!) servo and not issue.

don’t expect it to be amazing and actually meet the specs below (which are also fine in theory) and might not last that long - it’s a cheap servo.

Thanks for answering my question.

Nope the rears will not work since the TT01 upright is wider than the TT02 so will not fit in the TT02 rear lower arm. You can probably fit a TT02 rear upright onto a TT01, you’ll just need to add spacers between the lower arm and the upright.

The front TT01 steering knuckles will fit on the TT02 suspension, but they are shorter so it will change the angle of the upper and lower control arms, thus affecting your roll center. Remember the TT02 steering knuckle needs a spacer above or below it to keep the arms parallel to each other.

Thanks. I'll see if I can modify the TT01 uprights to make them fit the lower arms. Think I can trim down some plastic material on it so it becomes narrower.

What are you trying to achieve with the TT01 uprights? You don’t have the correct TT02 uprights available?

I just want to have the option of running 5x11 wheel bearings. 5x10 bearings in the TT02 uprights still work fine for me. Just want to try something new.

It looks like my TT-02 will need to go through a full teardown and rebuild. I had a high speed crash a while back and just now realized that the impact was so hard that the motor mount hole in the tub chassis is destroyed. The diff cover is also cracked so I'll be inspecting for other possible damage when it's torn down. It hit the curb head on @ 35+mph. Completely my fault. It was still all in one piece and still drivable afterwards, which I didn't expect it to be. Since I am planning to do a complete inspection and rebuild, I also plan to take this opportunity to attempt making it my 1st dedicated rain/wet car with stainless steel hardware, stainless steel bearings and all waterproof electronics.

Ouchie!

Thankfully, these are inexpensive kits to work on.

using 42102 TRF dampers, with standard length spring, no way I could get 5mm & 5,2mm ride height
Changed the using short springs (for M chassis dampers), yes... got the ride height.

Just came across this oil filled differential kit made by Yeah Racing. https://www.rcmart.com/yeah-racing-o...t-020-00104972

Wonder how well it works compared to the one made by 3racing and the Tamiya one.

Droop limiters for 54874 upper arms
 

For those using tam 54874 upper arms, I designed droop limiters for the TT02. If you want the .stl file for printing, PM me.

Oooh, that's a good design. Nicely done.

Has anyone successfully stretched out the suspension to accommodate a 210mm body (Yes its 210, not 200, its a Kyosho Ferrari 575 GTC LM)....?
The widest I have managed to get my TT02R thus far is 190mm using the 50808 long axles.......
I'm trying to avoid using the 12mm wheel hex hub adapters because then the geometry gets really funky...If there is a way to extend the suspension...I'm all ears.
Any one attempted this experiment already?

I believe the arms themselves are on thingiverse. Use your favorite 3d modeling program to add a few MM to each arm, and get some longer turnbuckles for the top?

Can't believe I didn't think of that., thank you.
Those files aren't up to my standards, but thats the direction I'll take. I'll draft them myself and find some suitable length driveshafts....

Whipped these arms up to increase the the width by 10mm overall (5mm per arm) for a first kick at the can.
I'll take some pictures once the printing is complete next week.

I've been parsing through lots of information in the process this week of setting up my first TT-02. I've updated the Wiki at the top of the page with much of the general information. I'll continue as I learn. Hope it helps some other new guys get the info a bit quicker. See you guys on the track.

3d parts
 

do you know of any other parts that are good to be 3d printed for a tt02? I got a printer for Xmas and have been browsing Thingiverse and elsewhere for parts that might be useful. Also could you send me that .stl
thanks

Hi, new to the forum :smile:. Just saw tamiya's 2021 releases and saw tamiya is releasing a tt02 on tracks :nod:. Item: 58690 Landfreeder Quadtrack (TT-02FT) Looks like it uses stock arms but replaces uprights with new ones. Also seems to come with a lexan chassis cover, first official cover by tamiya since the tb01? I spy friction dampers too :weird:. I have also got a tt02 to show you all, but have to wait untill I can post pics, since this is my first post.​​​

There is also a TT02 Ford GT40 and Ford Escort Cosworth 👍

Lexan cover will come in handy for rallying

Painted up a Bittydesign Seven20 Body in McLaren colors for some Spec GT racing...

I need to replace the gasket on the gear diff 54875. I can’t seem to find the part number for the gasket. Anybody know?
