Cheers, yep I'm going for the 80/50 combo my current 80t is worn so I have a new one coming in the post

This car really needs a "motor plate" which allows free selection of motor position.....

I guess you mean something like this ;)

Great! Already ordered.
Wondered who´ll be the first to manufacture this.
Some days ago there were nearly no tuning parts for TT02 at RC-mart...:D

Br and thanks for the info,
Matthias

hi guys,

New to on-road, and it seems this will be my first touring car, just wanna ask about the durability of it, is it good enough for a newbie like me (you know crashes, lol)?
And also, aside from the bearings, what other upgrades will be more immediate? Shocks maybe? Are the stock plastic shocks good enough, are they oil shocks?
Any other advice that i should know?
Btw, will be using the stock motor at first.

Thanks a lot for any help i can get.

The only available upgrades from Tamiya from where you're from are bearings and the shocks (the stocks are friction not oil).

Thanks a lot for the heads up man, it's better they have less upgrade options, lol.

Here is a build and review I did,
http://www.thercracer.com/2013/05/ta...nd-review.html

but to answer your questions you only really need bearings to start off with. You can upgrade the shocks later the std friction shocks are fine for your first few races and they are indestructible :)

Thanks a ton for the advises and great review man, actually i read it last night and that's why i'm leaning to this TT-02(and of course it's also due to a good friend and off road buddy of mine having one and convinced me to this TT, you know who you are brother, hehe), so i won't mind the shocks now and just look for the bearings, don't like the high friction plastic bushings too, cheers

My car finally arrived yesterday and i'm building the car at this moment.
The car looks great and it's a big improvement if you want to do some maintenance on the gears.
This chassis was definately designed for buggy or rally purpose, this because of the limited gear ratio and i regrate that the body holes are pre drilled :(
I've allready installed some universals with lightweight swing shafts, used some titanium or blue alu screws. So far i saved +30Gr of weight :)

Today i had my first test drive with this chassis in my street and i noticed that the car was more stable over my TT-01R E-type allthough my TT-01E has a very good set-up.
Only option parts i used were light weight universals, some titanium and alu screws, alu turnbuckles and a set of TRF mini dampers.
The car feld stable and dialed with tamiya medium narrow radial tires.
I also put my TT-01E and my TT-02 with the same electronics on a weight scale and the TT-02 weights about 40grams less, what's always a good thing :)
The car is definately worth the money.

can you take a pic on the alu dampers from mini. ty

by the way, the plastic knuckles breaks easily. the second time i bought a knuckle parts =(

spurred and pinion used
70 27 - slow
68 - 27 - bit faster
64 - 29 - can compete but tt01 28 - 55 is faster
61 - 29 - loving it
58 - 29 - not sure yet.

Ill be buying yeah racing alum knucles and toe in rear. im having difficulty to lower down to 5mm ride height,
any tips there when using mini dampers? or maybe a picture. thanks in advance

here are some pictures of my car with TRF mini dampers

H. What are the part nos will I need to get for the 61-29? Tamiya stock parts? Do I need to replace front and rear gears? Thanks!

@addictedblue

Thanks mate, this is very helpful on fixing my TT02.
Any tips on installing the front arms and knuckles? i just broke 2 sets now because of the fragile build or plastic part of the TT02. this is the only concern i have on TT02 right now. it breaks easily. is it wiser to add anti wear grease on the moving plastic parts?

@primaveralaw

61T from tt01, then use a sand paper to remove the additional plastic until it fits well to the drive shaft knuckle.

HI. This seems to be an awesome setup. Parts for tt02 are quite limited here. Would you be kind enough to provide the part nos. or sizes of the parts you used particularly the universals and the turnbuckles?

Appreciate it.

Here are some part nrs:

53506 39mm light weight swing shaft (TA04)
53499 Wheel axle for assembly universal
53681 Titanium wheel axle for assemblu universal (but this is very expensive)
53500 cross joints for universal

You can also choose for the complete universal set for TA04/TT-01 with part nr 53792 (this is the cheapest solution)

I used tamiya alu 3x23 turnbuckles, don't know the part nr as i allready had these.

Hope this helps you

I don't think ani wear grease on plastiek moving parts is good, this because it attracks dust and will give more wear then normal.
The only tip i can come up with is, practice as much as possible and that way you will have more control over the car and you break less parts.
The plastic parts are indeed soft.
I did use some 0,1 or 0,2x5mm shim plates to have less slop in de suspension parts.

Hope this helps

Do you have a picture of this modification?

The 24 hours of jackson moves to the TT02 next year. The car simply came out too late and too few to use this year. but i'm sure after folks here are done with it, we'll know what makes it bomb proof like its predecessor. -R

double post doh

Will post it later after work. I was thinking to remove the bumber at the back of the car, would it make a big difference on its aero? But will surely reduce big amounth of weight on the car. What are your thoughts on this?

Thx for taking the time to get a picture of the modification.

I personally don't see the point of cutting the rear bumper, the weight gain is maybe about 10gr or so, but is it worth to do so?
What about the strength of that part, possibly it will be ok but i prefer to leave it as it is, but that's just my opinion.

Today i received the high speed gear set for my TT-02 and i've tried to install the 0.4 90T spur from tamiya and it works great.
Been using it with a 48T pinion on motormount position for the 0.6 23T pinion, the gears meshing up as it should be and even the noise of the car is a bit less then normal.
This combination should give your car a ratio of 4.88, it would be equal of a TT-01 using a 55T spur with a 29T pinion (but we all know that this combination is normally not possible)
So the TT-02 can be faster then a TT-01 car, this with a better handling car should give you a benefit at the track :)

Thanks for sharing this info, seems there are some combinations that work with module 0,4 and the stock motormount!:tire:
A bit long for our track running on CE-4 with NimH by law at the moment, but maybe after switching to LIPO next year in our spec class I´ll give that combo a try!

Br,
Matthias

I tried 61-29 and speed was good on the straight. I had to take out the engine cover for cooling as the esc would shut down because of high motor temps.
I find this combo wanting in torque in the technical portions. Anyone try 61-28, 27 or 25?

Also, how is the high speed gear set as against the tt01's 55-28 set ups.

Would you say that this gearing is optimal? Good for long straights but enough power to manage the inside?

That depends on the length of the track, we have some pretty large circuits here (with some straights of 80m, followed by some high speed turns) meaning that high speed is crucial for topqualifying.
I will be trying to mount a 49,50 or 51T pinion with a 90T spur, when those pinions arrive.
I tested the 48T pinion with 90T spur for about 7 - 8 minutes in my street and the motor still seemed to be cool.
I even did full throttle/break (continue repeating this) testing for about 2 minutes and the motor wasn't hot at all.
I especially did this testing for the gear mesh, if it wasn't propper then the spur would have been destroyed by doing that.
About the acceleration out of turns seems also to be better over a TT-01, that's my opinion. The drive train is much better and this gives the car in my opinion a better throttle respons.

Hope this helps

This helps a lot. Thank you. I have asked around and our local track regulars for stock touring are using tt01s geared 55-28. Straight is not as long as yours at 80m with 4 hairpins, a sweeper and 2 chicanes. Will the 90-48 combo be enough to go along with a 55-28?

I also understand that the internal gear ratio of tt01 and tt02 are the same at 2.6. Does this mean that I can also go 55-28 using the sanding method described a couple of posts earlier?

Sorry for the multitude of q's. New to TC gearing. Thanks in advance!

If it was up to me i would go for the 90T/48 combination.
This should give you the benefit of being faster on the straight and not loosing much when coming out of the corners (if there could be a disadvantage of the acceleration). From what i've noticed about the TT-02 is that it has a better throttle respons then a TT-01. But is a personal feeling.
This can only be measured on a track with looking at the laptimes.
Gear ratio of a TT-01 with 55T/28T combination is 5.11 and the TT-02 with a 90T/48T combination has a low 4.88.
I'm not sure if a 90T/46T (gives a 5.09 gear ratio)combination would be possible (cause of the gear meshing), cause that could be an even better choice for gear ratio.

Stock for stock , i didn't find the tt02 to be that much better than 01.

Somewhat disappointed.

I tried the 90/46t and I am very happy with it. I noticed that the teu105s thermal sensor is somewhat erratic. It shuts down in different temps. Anyone experience this?

For those asking how to get your ratio down... the speed gear set is pretty much like what I made for my TT-01. Take a look... http://www.rctech.net/forum/electric...l#post10640495 Post #2057 for reference. Won the points championship with it. All a person has to do for the motor plate is take a flat piece of Aluminum and cut it to shape to create a cam type setup. I used a Losi Street Weapon motor plate as my original guide. If people were interested in this, I could make them pretty easy. If I got 5 people, you can bet I'd make them for you guys. If I got 15 people, I'd make them and offer an entire kit to get your FDR down to around 4 for those interested. I love helping people out. It's probably my favorite thing about this hobby.

Did you tried it on motor position 22T??
I haven't tried it yet.
Did you notice the lower noice cause of using the 04 pinion/spur combo?

I might've tried it on pos 21t. Indeed it is very very quiet.

I will try it to see how the gear mesh is, thx for the info.
It's nice to see how we all can help each other out with questions and answers. That's the best thing about forums.

Hi Guys

I have raced my car in 17.5 blinky with an FDR of 4.35 :) I have posted on how to do it on my blog here.

It runs really well and the car was feeling very nice and the motor temp was pretty low compared to the other cars :)

http://www.thercracer.com/2013/07/ho...inky-with.html

Thx for sharing this info.

Hey guys,
had the first raceday with the TT02, and it was fun.
We had ultraclose racing in our hobby class, fighting with 2 TT02 against Ta05 and TT01 and some other brands.
I managed to take 2nd place in the A-final behind my buddy with his new TA05.
So I was back in the same place as last race with my TT01. As E36BMW already stated, it´s no revolution but an evolution from the TT01. I didn´t expect something else, but I like the small improvements, which will make the TT02 an easy car over runtime.
I drove 29/64 gearing with TB03 spur gear adapter, whilst my other buddy running his TT02 on 28/61 with TT01 spur gear.
We all run on CE-4 silvercan and 30000Nimh by spec.
I was running bone stock the car with LRP QC-3 speedo and plastic CVA from the parts box. Handling felt very stable with kit springs, it was fun to drive.;)
What was an nice side notice: It has an integrated transponder stay: You can easily clamp your personal transponder under the Bumper plate in the middle, it can´t go anywhere and is safe in crashes...

Br,
Matthias

I've tried to mount 50T pinion on a 90T spur (ratio of 4.68) and it does fit, but this is absolutely the biggest pinion you can mount.
Gear mesh is a perfect fit.
You even need to use a dremel to get some extra free space directly above the pinion, but this modification is done in a few minutes and it's very easy.
So when you need to use tamiya spur/pinions this is the maximum ratio you can use on the TT-02.
