Woot. I just came into possession of a previously loved Tamiya TT-02 (Nissan Skyline body). It has a4000kv brushless in it, but is otherwise stock. Recommended spare parts (cheap upgrades)? Required upgrades?
Also however, some screws have stripped, any ideas on repairing/replacing screws? (god I hate Philips screw heads).
Many thanks.

My 7 yeas son often has a stock TT-02 (LaFerrari) with 2 upgrades: GPM Aluminum Front Knuckle and Bearings.
He often crashes and the front dog bones are very often coming out (and then the outer joint is ejected).
Any suggestion to prevent that?
I did not put o-ring inside. I noticed that for TT-02S there is this o-ring and it seems to be also provided with the kid.
How do you fit a Kimbrough Medium servo saver ? The top hole is not high enough and can touch the shaft.

CVD front driveshafts are the simple fix for this, it's one of the first mods most racers carry out. Throwing dog bones is something TT02s do. The bone is quite short and the suspension arms are a tad too flexible. A stronger servo saver does help too. I'm not sure a Kimbrough medium one will fit. If the height is insufficient that's that. If you're using the stock link arm you could replace it by using a ballstud at each end and a turnbuckle rod as they're smaller in cross section and might get you an extra millimetre or so.
If I go gpm, can I keep the standard plastic outer joint ?

I run old GPM ones in mine, they were steel and unbreakable. I think the current ones might have an alloy bone. It replaces the kit shaft and axle stub and allows you to retain the big gearbox outdrive (that you were previously losing all the time). If you were to go with a proper Tamiya CVD you'd need to replace the gearbox cup with a smaller metal one, I use M05 Mini ones on my full race TT02S as they're cheap and easily available.

Hello All,
I am adding a bit (bunch?) more power to the TT02 and just bought a secondhand 10.5T motor. Looking at a FDR chart and it looks like they recommend anything from a low 5 to a low 6:1 FDR on a fixed timing ESC. Since I am bashing I am thinking somewhere in the high 5's to low 6's to keep the heat down and run time up as much as possible. With that said I am wondering what the largest 64P Spur the TT02 will accept? I have an 85T in there now and there is a bit more room but curious how big you can go?
Thanks.
Cheers,
Jim

I actually found the stock spur which equates to just about a 91T 64P so you have confirmed my suspensions. I have been running a 85T spur with a 51T pinion on my 17.5 so I already opened up the gear cover a bit.
I have just about 10 hours of run time with a 17.5 on 64P gears with no issues so I am going to stick with 64P. I opened up the gear cover this morning to take a look at the room and saw that I had a bit of dust in there, I pulled the spur and pinion and cleaned them up and there was very little wear. My bashing consists of setting up a course on two adjacent tennis courts and doing hot laps so I would guess my usage is more akin to racing on a circuit then true bashing.
Thanks again for the info.

Jim

The TT02 is getting another upgrade :-). 8 years ago our house was robbed and the crooks took a lot of my RC gear including an, at the time, fairly high end Futaba surface radio. When it was stolen I was not doing a lot of surface RC so I bought a Futaba T2PH which is a VERY simple AM radio that did what I needed at the time. I also fly a lot of e-powered planes and gliders and have always flown Futaba's upper mid range Tx's and over the last 15 years I have learned to love the ability to configure the newer digital radios that offer EXP, End Points, digital trims, etc.
As I am spending a bit more time enjoying the TT02 and trying to get the best out of it I see where some of those options could be useful on RC cars. I did a lot of reading on the lower end digital radios and decided on the Futaba 3PV. I kept a keen eye on the classifieds but missed the couple that came up in the last month. The other day when I was ordering gears for the new motor I saw that A Main had a $10 off coupon for orders of $100 or more and pulled the trigger. I am looking forward to checking out the TT02 with its new found power and control :-).

Hello All,
I got home late yesterday from a work trip and there was a box sitting for me.
First up was to install the 3PV, For the money I think it is pretty nice, I was worried that for the price and weight it would feel cheap but that is not the case. The menu is a bit cumbersome for the fact that you have to cycle through all the programming every time you want to make a change but I was able to do everything I wanted without reading the instructions. It is nice having adjustable end points as I was able to get a few more degrees of steering lock. I have not had a chance to run it on my circuit to fine tune it to my liking but I like it so far.
I then tackled putting the new motor in. I bought a used Trackstar 10.5T V2, which looks like new, for $20 shipped. The guy I bought it from said he ran it in a TC for three nights at a carpet track and other then seeing it was soldered it looks like it is brand new. I geared it with a 91T spur and a 39T pinion for a 6.06:1 FDR. I spun it up for a second and noted that one of the Tamiya Super Grips was coming off the wheel so I switched over to a set of USGT tires and took it out front. Not having any experience with lower turn BL motors I was concerned that a 10.5 might be to much for the TT02 but it actually feels pretty perfect. The car will get a bit of wheel spin off the line if you drop the hammer and the top speed is noticeably higher but it is smooth and totally controllable.....I think this is going to be fun. I ran it around for about 5 minutes and did a finger check of the temp. It was 26* out and the motor felt just slightly warm so I did not even put the temp gun on it, I am running a blinky ESC. For the time being I will leave this gearing in it and wait to see what happens as it warms up but thinking I can go a bit steeper if I want to. I was hoping to do some hot laps on the tennis courts today at lunch but we got a couple inches of snow this morning so that will not be happening.
Cheers,
Jim

TT02 Type S setting toe in rear
Does anyone has an idea how to set rear toe in of a TT02S? I just run stock challange on carpet and 3 degree toe in rear makes the car to slow on the straight sometimes.
