This shaft works. You’ll need to shim it with 0.5 to 0.6 mm.

Man, I was buying a TT02 Type S online, and turns out they were sold out but still listed. I got to thinking- the cost of the type S is like 45 bucks off the price of the TA08 Pro, not counting the traditional 150 bucks of Tamiya go fast/look fast blue stuff. I gotta ask, why even buy the TT02? Other than TCS races, I don't see the point. Enlighten me, guys.

I was peer pressured into getting one, and have no regrets...yes, the base kit is riddled with issues, but it's a lot of fun to tune and customize and race. It's a pretty rewarding build once you get it sorted.

My group of friends does parking lot racing, so it was an easy way to get everyone on a spec chassis that came with a motor and ESC (my group's loose spec rules are stock motor, ESC, & spur gear), and the aftermarket is great for keeping everyone's cars up and running. Spare parts and options are plentiful from other companies besides Tamiya too.

We race other cars too, but the TT02 races are the ones that really count due to the cars all being so evenly matched.

During our pre-season (when no spec rules applied), I had a 10.5T sensored brushless combo in there and it performed great (albeit a bit squirrely if you were heavy on the throttle)!

Default My latest project.

Need a shorty battery and to make or get some drift tires for 32mm rims. The plugless design for the LEDs I scratch built works wonderfully on my RC4WD TF2 Scale Truck so I'm going to do a slight variation for this build. Raman you may have already seen it over on Rccrawler forums on my build thread. I'm RC Perspective over there.

I'll post more pics when it's finally finished. Waiting on another set of the Tamiya 2 piece rims in chrome. Still have to paint the 73 Carrera RSR body.

If you have the $, always better to got with w TA series over a TT series. I keep the S around for TCs Spec Novice, although this will probably be the last year my son can run it. After that it will be repurposed to street basher for him.

I only bash so that's my reasoning for the TT02 purchases I've made. Spent enough on the first one to buy two TA chassis, but that's not what I wanted because I'm not competing or racing.

Maybe the "Fun" factor is a reason why people buy the TT-01 and TT-02 cars. There are no other sedan kits out there today that come with a body, tires, rims, motor, and ESC for under $100. Some Asian online stores even sell a new TT-02 kit for under $81 USD which is an amazing price. The tub chassis, sealed (relatively well) shaft drive systems and enclosed spur/pinion makes for a great parking lot basher and with the addition of a few inexpensive upgrades these cars make decent club racers. Tamiya bodies are some of the best detailed out there and the included decal sheets make it easy to have a sharp looking car. Add on some LED lights and they are cooler still.

The TA-08 is nice, and is likely a better handling chassis, but it is still a plastic tub chassis kit that costs more than three times the price of a TT-02 and doesn't include the body, tires, motor, ESC or anything else for that matter.

Since I changed to on road racing, the races where I have had the most fun have been in a TT-01 (TT-02) Cup, where the racing bodies were banned.

Agree with all your points. Only exception is the Type R, RR, S, SR.. which don’t include bodies , ESC and are priced closer to a TA chassis

I appreciate the points you all made about the TT02. I guess I just got a little intimidated by the price of all the stuff I had lined up to purchase once I got the chassis. After buying a TA08, I have the Tamiya sickness. If its blue, I gotta have it.Still gonna get a TT02. If anything, it'll look good on the shelf. Im thinking of quitting RC to be a crack addict. I hear its cheaper...lol

This hobby can be addictive at times, there is no doubt. My TT-02 White Special started box stock but like most people I was unable to resist the allure of the blue bits. I went for the Yeah Racing parts as they are less expensive than Tamiya but work just as well. Mine has the steel front & rear joint cups, steel CVD's, alloy ball bearing steering, alloy main shaft joints, alloy front and rear upper adjustable arm sets, adjustable motor mount, solid axle diff insert, front upper bumper plate, a set of threaded blue shocks, and a set of 3 degree rear hub carriers. I did use the blue Tamiya center shaft and the Tamiya High Speed Gear adapter, plus a set of VBC Racing clamping wheel hexes. I also had a spur gear cover 3D printed so that I can use larger pinion gears needed when running brushless motors. I topped it off with a McCallister Mustang GT body and have a set of Gravity RC USGT tires mounted.

With all local R/C racing cancelled due to the pandemic, she sits on a shelf waiting for better days ahead. Seems silly I admit but I am weak.

Wow... that's a lot of blue. I presume this is a shelf queen and not a runner?
