When Tamiya announced the anniversary edition of the TA-02, I decided to build another TA-02 as a runner. As my "onroad career" started in the early 90s with the TA-01 chassis, first offroad as a Manta Ray, later also as an onroader. But since I planned to equip my TA-02 with all hop-ups it was soon clear that Tamiya`s Anniversary Porsche is not the right starting point. So I decided to create my own 25th Anniversary TA02. The first thing to do was to get the necessary parts. Fortunately I have a large stock of spare parts and tuning parts (like the Tamiya 53226 Front Hub Carrier). All other parts were ordered. However, I found out later that this are by far not all the parts I need, but more about that later. The complete chassis is built up with aluminum and titanium screws. At the front axle a spool, at the rear axle a gear diff will do its job. The engine will be a Tamiya Super Stock TZ (just because of the colour). For more weight savings, I use the Top Force hollow gear axles. It was a lot of work to find the right cardans for front and rear. Finally I use M-Chassis wheel axles 54623 in combination with lightweight swing shafts 53502 on the rear and double cardans with Low friction cardan shafts 42360 on the front axle. For the shocks I use Tamiya TRF shocks with black springs. After several hours the front and rear differential housing is completed. The next step is the installation of the carbon double deck. Here I decided to use chassis plates from a third-party manufacturer, since the Tamiya carbon decks are not available at this time.

Nice work once again! 👏🏻 👍🏻

Better have parts in stock you don't need, than the other way.

Yes the Super Stock be be opened easily. I have changed to Ball bearings in my TOP Force Evolution too. But maybe a Super Stock RZ will fit better to all that blue alloy parts.

Last weekend we were off for some schoolyard racing. It was the first time for the TA-03F to hit the track and it performs "out of build" better than expected. Even though you can drive it like a FWD car and it has been eaten some tires, it was a lot of fun! But unfortunately the front differential got loose. I used diff puty in he front gear case but it didn`t last long. Next time I will use silicon ear plugs to stiffen the diff. If this won`t be working i maybe change to ball differential in the front, or use a spool. I also decided to change the dampers. Always have problems with the vintage dampers, as they trap air after a few runs. So I bought a Tamiya 42102 TRF Damper set and equipped it with red alloy caps, to make it better fit to the rest of the car. We use the Ride Pre-Cut tires for our Racing Series as they proposing a good compromise between grip and durability. But the rims of the preglued wheel set don`t fit quite well to the Nissan Skyline Calsonic body, so I have changed to Tamiya 53471 5-Spoke wheels. The ride tires fits perfectly and it looks way better than before. So I am prepared for the next race...

Last weekend it was time for the first outdoor run this year. Was a lot of fun and the FF-01 performed great. Only the dampers trapped some air, once again. So I decided to change them. As I got no blue parts on my FF-01, the Tamiya 42102 damper set is equipped with some black Square Hop Up parts. The Square parts fit great and I hope that I don`t have to rebuild the dampers after every run. Also I have changed the silver servo stay to black ones. Maybe I will change the screws to Titanium once, but for now I am happy: Last but not least some awesome news: wtcc and me contract a friend with the FF-01 fever, so next time we be racing with three FF-01!

Let`s go on with the build... After the painting of the body, there were still many parts for masking: But I like the result: After spending a lot of time in bodywork, I had to realize that the body didn't fit, because of the front motor of the TA-03F. I`ve not checked it before, because the TA-03 was disassemble at that time. I was really disappointed and and I wonder how I should explain to my wife, that I will need another body? No problem my wife said "Don`t worry just buy another chassis for the Mercedes body and another body for the TA-03". I had never expected that kind of answer! But first I worked on the chassis a bit more. Managed to fit double cardans at the front. Therefore the front knuckles had been changed to plastic ones, to fit the new bearings in. Not much space, but it works real smooth und no loss of steering angle. As time is rare and I don`t want to do another body yet, I fall back on a body in storage. Fits very good and matches to the Primera: Both chassis will go out for a track day tomorrow. Can`t wait to see how it performs!

Yes the Red servo stays are quite rare. I am going to use a Robitronic Cube 2, as it is equipped with a lipo cut off.

Let's complete the build... First of all, the carbon deck. This is what a TA-03F should look like: As there are some red accents (Super Stock TZ, ESC) I decided to add a little bit more: The next steps took a lot of time, especially the electronics. But Tamiya was far ahead of the times with the carbon battery mount, because my shortys are fitting perfectly! And here it is: I have also solved the heat sinking problem, by adding a fan. Now it is time for working on the body...

Yes I am going for full option, as it will be a runner I only change some parts for better handling/easier maintenance.

I have managed to get new black B-parts. So I spent some time completing the rear gear box, also fitted the dampers and anti-roll-bars. What a difference!

Thank you! Awesome work! Now I can complete my Super Astute, too.

Tamiya 53357 is already installed. But this aluminium motor plate sits in the middle, so no Chance to dissipate the heat.

Thanks for the setup, I will assume this 1:1

Today some brand new A-parts arrived and I could`nt resist to continue the build. I just love these little tuning parts, like the carbon axle in the front. Also mounted an adjustable upper arm set, as well as Modul 0.6 gears. Finally the front is done. Looks really solid, but I am just wondering how I could control of the motor heat. But no worry, Tamiya takes care of this problem, by including an air channel for cooling.

Yes

After everything has been cleaned, it's time for assembly. First, the carbon deck was sanded and sealed and a protective film was applied: So everything is prepared and the building started. First of all I am going to use gear diffs at front and rear: But then the problems started. The front gear box is broken on several positions. Luckily I will get new black A-Parts to fix this issue. So I decided to start with the rear. But unfortunately the rear gear box is damaged too. Black B-Parts are sold out everywhere, so I will try to fix it, as there are no heavy loads at the gear cover. But this arrested me to continue the build, so I started to paint the body. I am sure you can guess what body I have choosen.

Thanks for the informations! Did not have known that these parts are rare, as I´ve got a second pair with it

I have a TA-03R-TRF also, but sits on the shelf. Like this unusal 4WD layout, so I give it a try. Already worked a little bit on the TA-03F. The previous owner replaced the J5 part to aluminium posts. They were blue anodized and unfortunately not in the Tamiya blue. So I decided to polish it, think this will fit better to the other silver aluminium parts. Small parts, but lot of work... The David Jun is euipped with a lot of aluminium parts. Originally it comes with CVDs in the front only, but I have another set in my FF-01 box, so why not have CVDs in the rear too?

As I have to wait for some parts to be delivered for the Super Astute, I am devoting myself to another project: TA-03F PRO David Jun Although I had never own a TA-03 before I am torn between love and hate of this chassis. Last year I got this special edition from Japan for a good price, so I`ll have to give it a try. The car is quite in good conditions, even if though it was used. Due to the FF-01 addiction during the last year, there had been no time to spend on this project. But I had used the meanwhile to get some Hop-Ups: Now it is time to dissasemble the kit and clean everthing up. Since it`s going to be a runner I will make some modifications. First I will use gear diffs at the front and rear and Modul 0.6 instead of 0.4 also the torque splitter will be removed. Regarding to the setup I will try to keep it very similar to my FF-01 setup, e.g. blue springs in the front, reds in the rear. But I don`t know what to do with the anti-roll bars... Do you have some recommendations? I want to mount them, just because they are neon color.

First I wanted to use a black Sport Tuned Motor. But unfortunately the axle of the motor is too short for the Super Astute. Also the Torque Tuned doesn`t fit, so I will use the Lightly Tuned Motor. Now I have to wait for some more carbon parts to continue the building. Fortunately @wtcc5 will help me once again with an awesome 3d-print part...

Yes All bearings are mounted on the axle. One outside und two inside. Tamiya 53791 are 70mm cardan. The ones I use are just 64mm, so I have no problem with the additional bearing.

Sonneberg sounds great! Never been there... Would be great to have a group of Tamiya Vintage Drivers out there.

As mentioned before I wanted to equip my Super Astute with double cardans. It was a long way to go, a lot of try and error, but I finally did it! I have tested a lot of different TRF cardans and waisted some money. Finally all you need is Tamiya 42284 (TRF 503 Rear Double Cardan Set). Unfortunately this set is sold out everywhere. Fortunately I could get the parts separately. To adjust the wheel axle I use three ball bearings (one 5x11x4mm and two 5x11x3mm). Now it fits perfectly. I am so happy!

🤔 I don't want to be the bad guy, but I guess there will be no grip on this concrete floor in your garage. Also I am no fan of racing on cobblestones or racing with 1:8s. I think for onroad racing we should visit a track. Offroad maybe more opportunities.
