Default tb-02 noob

Hi all

OK i've picked up a tb02 on Sunday took the Nissan GTR. It was a bit of an impulse buy after having a shyte mimi race day.

So i've got this thing build and now it's time for some hop-ups.

I've been reading thru most of this thread today & yesterday and made up my shopping list (in buying order).

Stabilizer (53677)
Aluminum Motor Mount (53680)
27T Pinion (49230)
52TSpur (53552)
28T 29T Pinion Set (53262)
Front Damper Stay (50998)
Rear Damper Stay (50999)
SSG Carbon Center Plate (53679)
Aluminum Racing Steering (53678)

Is there anything i'm :
missing?
shouldn't buy?
move up in the buying order?

I'm currenlty running 21/58 which gives me 7.18, i'm going for 27/55 = 5.01 which should be perfect for my local race tracks.

I also made this little pinion/spur sheet (see attached) giving me the gear ratio and tb02 mounting position. (this seems ok, but i'm new to the whole spur/pinion thing)

Any other tips/suggestions to get my tb moVing will be sweet.

Cheers

The 28-29 tooth pinion set is the wrong pitch. That is for a fine tooth gear .4 module. This car uses the .6 module

Also curious where you found a 49 tooth spur, and a 64 spur that use the .6 module pitch?

on the 49/64 spur issue : i just worked out the ratios for those 2, didn't know they don't make them.

So now the 28/29 pinion should also not be needed, they where just for the 49T spur anyways.

Thanks for the info dsrbltoys. I am running a chameleon 2 and I hear they a a little higher rpm and less torque than your reedy so I will probably start with one or two less teeth on the pinion. It looks like I should be okay with the 55t spur. I was also wondering if there was any word about a carbon tub chassis in the works for this car? I have sold my xxx-s and this is going to be my only electric touring car so I would like to upgrade a couple of things on it for regular competition but in general I didn't think the car looked too bad.

If you put the carbon decks on it, the car is no longer a TB02, it becomes an EVOIII. The parts needed are 50996 main chassis, and 50997 upper chassis plate.

If they are very tight you will lose steering.

I run my diffs quite loose on the trackwork EvoIIIs, but my TB02 has 'em real tight for drift duty.

Thanks WC, Im racing today at the same track I was having problems with so hopefully it'll resolve the issues.

If anyone needs Tamiya parts PM Kevin he will be glad to get parts out of his personal inventory. At times I think it rivals Tamiya America's inventory.

The orginal TB02 Ball diffs feel inconsistent when rotated freely. It's smooth but gets tight then loose when rotated slowly. have you guys experience this situation and does it have any effect on performance? Any solution besides putting together a new EVO 3 diff?

Use any of the other EVOIII diff outdrives. If you want durabilty use the black ones from the EVOIII (50992). Use the white (53627) ones if you want smoothness, w/o being able to tighten as much as the black set. I use the black in front , and the white in back.

I found the white ones bottomed out if over tightened. I had to remove some of the support for the 5x8 bearing to run this diff on carpet with foam.

Well ran my TB-02 SS ( ) at the Hobbyworks TCS race this weekend in Maryland. I was TQ and won the A main. Not bad as the last 4 laps I only had frontwheel drive as my rear diff outdrive broke and I lost my dog bone.

Car was on rails and worked perfectly. I had one or 2 )4's that could pull me just about a car lenght down the huge straightaway but in the infield it was all over. I geared 22/58 with a Monster stock motor. I ran Type A's and the car was liking running on velcro.
