If I remember correctly the diff locker doesn't fit in the diff housing that can hold fluid. You have to use a plain tt02 housing.

I have both the TT-01 and TT-02 stock diffs each with a diff locker installed. They are a drop fit and easily fit without any difficulties or issues.

The TT02RR comes with oil filled diffs so I need to get the TT02 stock diff housing and outdrives.

I believe the oil filled diffs are different, which explains things.

Type SR just popped up on eBay

Tamiya 1/10 TT02 SR 4 Wheel Drive Touring Car Chasis

You need to use the original TT02 diff case .. not the RR oil diff case.. The RR diff case is different

Is there a An upgrade kit for suspension for standard tt02? To 420arms ect

The 420 arms would drop right in. The only issue is if you use the droop screws / down stops. The 418 to 420 do not have drop screws m both sides as the type S arms. So you would have to drill those in yourself

Is TT02 always has one length of center shaft? The one I got as upgrade is 14cm end to end, but one my friend said he bought one is 12.5cm, I'm working on project that will use this shaft, 14cm is too long.

Should be one length. Just make sure you’re using the Tamiya one as reference and not an after market one

I was going back and forth with the guy on the price then someone grabbed it.

I want to run the type-s in gt2 and the tt02 in gt pro spec but I think that might be too ambitious of me.

GT2 is very competitive. Most are running the latest TA car line TA07 / TA08.

I've used it in two kits. Don't use anything under a 15-17t if you do sensored brushless. Can't handle 13.5t at normal timing for continuous 5+ minute hard bashing. Spread it out and no thermal cutoff. Which brings the point that the thermal cutoff works quite well

I picked up the 91 Audi and the 92 Audi. The 92 Audi no longer comes with the 04s ESC and instead comes with a brushed only ESC. The 1991 Audi kit still comes with the 04s.

Reading Raman's comment, they may no longer come with the 04s ESC. When I bought these two kits a couple months apart, the 91 came with it and the 92 didn't.

After the USTE Scale truck event which I had a blast with my Trail Finder 2 at(I know, nonTamiya but such an awesome scale leaf spring truck), I took the TT02R out. Man I missed this thing. I remember the Audi body having the issue of the high pressure area inside the back of the body at 55+ mph, and the tiny spoiler. So I switched out the rear body posts and put the Lance Evo body on with a much better spoiler.

On my tiny little culdesac I was able to squeeze 66mph out of it, whereas the Audi body was spinning out or veering off to the side over 60mph. Not wanting to cut up bodies to help this issue as I love the way the bodies look.

I robbed a few things off of the rally build, and put the Audi body on there for the time being. The parts wound up on my RWD drift build. Need to finish the body up and I am waiting on the chrome 2 piece wheels to come in for it. I have some fine mesh I'll be installing in the cutout brake ducts and grille opening.


Best I can describe the paint, from most angles it looks jet black, soon as the sun hits it it's deep blue with a crazy amount of pearl. Inspired by GM's tuxedo black from old old Corvettes. On this chassis I will also be integrating red LEDs into the chassis itself for underglow. Being I am unable to locate the Porsche headlight buckets I'll be modifying AA Maglite reflectors.

The updated garage. 3 TT02's and an RC4WD TF2.




Need to do some Lexan repair on the front bumper, but no broken parts this time. Turns out driving slow with a scale truck and learning to "pick your line" when crawling with leaf springs gives alot more control and patience with a speed run car. I'm still a little reckless with the speed run car, but not nearly as much as I was. Though I still shouldn't be trying for 70mph on my road without the room for it

I need to get around to build threads for my TT02s, but I've got one for the TF2 if anyone is interested. Lots of great work put into this truck!
