Hi,
Does anyone know how I can create a wide angle steering for the tt02 rather than buying the kit from broadtech? Everywhere else is sold out and their delivery costs are expensive.

Camocrouch 12-03-2014 12:25 AM

Hey Jim,

I can't remember - Did you get the type S? If so the addition of some active hobby high angle steering arms (or similar - I think broadtech now has a high angle set) could give you more steering angle as I assume the type S lower arm / c hub design could accept more angle (have one on order, will compare and let you know).
(For clarification, the broadtech kit does not come with high angle steering arms - You need to get them separately to achieve max steering angle).

If you didn't get the type s, perhaps you could go through the above manual and look at what parts are needed to convert just the front to Type S spec - I think many of the parts are common with other tamiyas and should be readily available from selmwhere like banzai hobby.

Good luck - Lettuce know how you go.

Sorry for the newbie question...does the TT-02 take a 190mm or 200mm body? Santa is bringing my 13-year old the Lexus Eneos kit for for Christmas and we wanted to save the stock body for the TCS series ��

Been running the TT-02 now with a speed passion 17.5T MMM motor&Cirtix club stock ESC with blinky setup and the car runs really great, even against some TRF or Yokomo cars
Very smooth and well balanced, just need to find that extra punch.
Will try a smaller pinion and give more motor timing on the MMM speed passion motor, perhaps changing the sensorboard with more timing.
After about 10 minutes of driving the motor temperature is between 55°C and 57°C without a fan, wich is good.

Did some small modification to get extra steering angle, i did cut a small part from the steering stopper where the steering block hits at the end of it's steering end point. Just to give that extra degrees of steering angle, it worked well.

Will do some more testing to improve my fastest laptimes;)

may I ask what is your spur and pinion combination?

I started with a 90T spur&43T pinion (FDR 5.44) with a fastest laptime of 12.5s with tamiya A-type tires and ended the training with a 90T spur&46T pinion (FDR 5.09) with a fastest laptime of 12.046s with tamiya C-type tires.
Track is a large indoor carpet track (30mx12)

Has anyone done an in-depth review on the TT02 type S yet? I've not seen much on the net including Youtube. I guess this version of the TT02 isn't in many people's hands yet outside of Japan. I'm sure something will appear soon, but I'm just not enjoying the wait.:cry:

Hint, hint...for thercracer.com;)

I'm looking for a VTA/USGT budget racer from a major company like Tamiya. I'm not interested in a TC4 (owned 2 already), Sakura (had 2 zeroes already), or Spec-R S2 (worried about parts support, honestly).

I haven't seen much of information about building de Type-S version eather, only 2 movies on Youtube when the car is on a track.
I'm still considering to buy one but my TT-02 is doing very well on the track.
Perhaps i should buy one and sell my TT-02, cause all the needed parts for building a regular TT-02 are included in the kit. Except the drive shafts.

I also have the Spec-R S2 and that car is very good aswell, parts can be found easily at TQracing. So parts for that car shouldn't be a problem.

The TT02s is pretty sweet, I'm very busy with real work atm but a review will come soon.. The only thing that bugs me is that there is no droop screw setting, you have to use spacers in the shocks. It's not a big issue and once you get a set-up then its cool its just that I do not like getting my fingers dirty :)

@Qatmix,

Always working, you should have some priorities about building tamiya cars :lol: (Just kidding)

Tamiya should design a new B8 part that gives the opportunity to use droop screws.
Very easy and could be sold as an option part.
I have been thinking of designing the part for myself and get it 3D printed;)

Yep, I was disappointed that they didnt just do this on the TT02s, I have tried to to a basic mod to the current part but it moved too much so it was not any good.

I need to do the 419 review before the TT02s.. Hopefully I'll get them done soon.

firefoxussr 01-13-2015 10:49 AM

Excited to join the TT02 crowd. Got a deal on ebay - an unbuilt parts set minus wheels, body, and electronics.

It's perfect for 'fixing' my Nikko Ferrari F430, this purchase solves these issues:
-RWD with open diff (nightmare)
-2S hardcase is rubberbanded in place cuz does not fit 7.2v round tray
-standard servo doesn't fit centered (non-standard on original car)'

The only other thing on my mind was- currently the car uses a stock TA02 Ferrari 360 Modena body, are the body post holes compatible with the TT02?

Smile 01-14-2015 02:39 AM

Yes, as far as I know, the Ferrari body's holes would fit, just like any other 190mm Tamiya body out there. The TT02 has reversible rear body posts, which means that even the older bodies would be compatible.

Thanks! Also I do like the RWD feel on my cup racer, which I think is cuz they did gear diff in front and ball diff in back. Anyone do ball diff in rear only for a TT 02/01?

I've mounted 2 ball diffs in my TT-02, the car runs great and has less noise.

You could easily ad a thin carbon fiber plate to the underside of the chassis, and then use the existing droop screw holes in the 418 arms that are on the S.

With whatever oil you used did you find a significant handling difference vs gear diffs?

Good to see this thread come to life again - even though I've moved on from on road/tt02.

I have been using 100.000, just enough to have the correct feeling.
The gear diff's are not consistent enough, you have to refill the gear diff's very often to get the right feeling and they leak a lot.
Or when you use AW grease the feeling at the start isn't the same as when you ran the car once or twice.
That's what makes the ball diff's a better choice, they are more consistent and moore smooth with less noice.

Currently i'm testing the car with a 17.5T motor and still i'm improving my lap times. Tonight and saterday i will be testing some setup changes.

Maybe someone could talk t-bone-racing.net to manufacture something like this for the TT02S? They make bumpers and skid plates for all sorts of R/C's already. Something similar to this would be perfect:

Ride height might not be so good afterwards, though.

I did some extra testing with the TT-02 and my fastest laptim improved with 0.1s with a fastest laptime of 11.940s.
Used softer damper oil and other tires.
Think i can go even faster cause this was done with batteries i'm using for practice, my other batteries give me more power.
This has been proven with my TRF418, i gained about 0.3seconds in my fastest lap.

Suspension Setup?
 
I'm running a TT02 with a pile of Hop-Ups. Aluminum suspension, oil shocks, aluminum steering linkage, driveshaft, universal axles, uprights, etc.
3.9 FDR (60t spur, 40t pinion).
21.5 turn Speed Passion VTA class.
2.5 degree rear toe-in.
1.0 (or a little less) degree front toe-out.
0.5 degree front negative camber.
100,000 weight front diff oil, 2000 rear.

Cornering issues.
Good turn initiation, followed by savage under-steer.

Suggestions?
General advice on setup welcome.

Check your ride height, it seems to me that once you turn in the chassis is rubbing on the ground, that can cause the car to under-steer dramatically.

Is is under-steering on power or off power?

your camera angle and lighting is good. Only thing I think is getting right into the build/video etc. What I personally find ruins a clip is when someone is talking for a good 1-2 minutes and not getting into the video. Keep up the good work

Thanks for the kind words and feedback. I appreciate it.

What you should do is say what you say before the build during the build. If you find this difficult you can edit the video.

A new TT-02R (84409) is announced at the toyfair of Nuremberg.
Looking forward to what new parts that this car will have.
Below is a link to Qatmix's website where you can see the car and other new releases from tamiya.

longuylander 01-28-2015 03:49 AM

Interesting about a TT02R, but that begs the questions... what are the differences between this and the Type S? Why would Tamiya release two these two cars so close to one another?

Camocrouch 01-28-2015 05:06 AM

Good question long guy.
The type s definetly has more significant changes with the addition of the different suspension arms, carbon damper stays, etc, plus most of the type r specs.
To me it seems like an in between step between the stock and the type s but it does rather complicate the lineup - will be interesting to see the price difference.
I think I also see alloy uprights in the rear...

I like the look of everything else - bodies for the drift kits, the DT03 truck, even the TT02 truck will be a cool option yet still keeping everything on the TT basic platform. I hope the TT truck has some sort of long suspension travel setup that I can adopt for rally!
I also hope they do one of those truck kits like the DT03T for the TT with the wide wheel setup...

Cheers
Crouch

Camocrouch 01-28-2015 05:27 AM

Just had a look at additional pics at Tamiyablog, looks like the TT truck doesn't have much in the way of extra shock travel (although I can't see the lower arms), adjustable turnbuckles for front toe, the smaller / metal dogbone /gearbox out drive setup and the reinforced grey pieces like the drift spec models.

These pics also confirm 3degree alloy rear uprights for the type r, high speed gear set, medium narrow tyres and again the smaller / metal dogbone /gearbox out drive setup...
Still confused as to where the type s and r sit in the lineup.

Cheers,
Crouch

The TT-02 type-R is a bit of a disappointment. It is also a limited edition kit (all 84 kits are limited) the Type-S is a proper kit (58600) so will stay around.

I want to see pictures of the TT02 carbon towers, I've seen the TT02S ones but I have been told there are some for the std TT02.

Darn, I thought it would be a permanent kit. Oh well. We are trying to set up a TT-02 class here in TX, and keeping an eye out for options.

Reason I'm posting mainly, is because I followed your guide online while getting into touring cars (thanks btw - I wouldn't have gotten into RC without it to be honest) and have a few questions about my TT-02 builds. Have 3 different ones (2 regulars and one D), and all the hop ups.

1) It will be run in soda treated parking lots. How should I set up the damper oil, springs and rebound? I have the tamiya spring set, and some HPI silvers that are popular. I also have the short TRFs, kit oil shocks, and even some aluminum M-chassis dampers I could put on there (and spring set), which lead to the next question.

2) It's been mentioned to build the kit at rally height so that the spacers to not contribute to breaking pieces on the front end. Would one then need to use m-chassis dampers to get back down to normal TC ride height?

3) Should I lock the front like a spool, or run the thick oil for these racing conditions? I have the locking pin part mentioned on your site. Pretty sure everyone runs a spool out here. No carpet anywhere. Mostly Xrays and TC6s on the track.

People generally run 5.5-6.5mm for the two locations where they set it up every week. Track is decent sized but not huge. People run around a 3.6-3.8 FDR in VTA if that's any help. :)

Thanks!!

ic-racer 01-29-2015 07:03 PM

Just finished my TT02 S-Spec kit. I set it up for VTA 25.5 but have not had it to the track yet.

Small changes I made from the kit:

Aluminum Steering Arms and middle connector
Aluminum center shaft
High Speed Gear Set (75/50 currently but yet to test at track)
Gear cover opened up to clear the 50t pinion
Shocks length set to 60mm front and 59mm rear. To do that I used 2mm front internal shock spacers and 2.5mm internal rear.
That gives rebound stroke about 2mm in rear and 3mm in front.
Moved rear shocks to outer lower mounting hole (otherwise car was too high even with no spring spacer)
2mm spring spacers front and rear gives me about 5mm ride height with VTA tires
I shortened the wheelbase at the back by moving the 3mm spacer (just to fit my existing body)
I shimmed to front and rear lower a-arms with some .2mm shims to take up play.

As a basic setup I put 1.5 camber all around. 1mm toe out in front.

I just kind of guessed based on how I have my 419 and 417 setup. I may get to run at the track this weekend.

addicted2blue 01-30-2015 12:41 AM

I did build my TT-02 as a rally and used those TRF mini dampers with the TRF touring car short spring set.
The length of my dampers was 57,5mm at the front and 58,5mm at the rear.
I think the front had an inner spacer of 1mm and 0,5mm for the rear.
But all this was used with the standard suspension and not the suspension of the type-s (TB evo IV suspension arms)
At the end (cause i sold the car last week) i used TT-01 ball diffs at the front and rear, i prefer this over the standard geardiffs.
