53994 TA05 IFS rear carbon damper stay
54019 TA05 IFS alu bulkhead

There are some more, can't remember them. Also the steering and rocker arms have bearings in them.

My problem is.... I tried the chassi on 4 seperate scales to weigh it in with lipo.
I then saw the difference in weight on each wheel. What puzzle me is the way it was distributed.
Front left was 370g
Rear right was 380g

Front right was 240g
Rear left was 250g

Why are the weight so unusual? Just to get a basis and that the place i measured was straight i also tested my TA04-R and that was 10g to 20g off on each corner.

My guess is the chassi has tweak in it, but it's brand new. I changed oil in dampers and put on new springs. No difference. I took the car apart to see and found nothing wrong.

Anyone have a clue?
Scales calibrated correctly and within tolerance of each other?

Try removing (disconnecting) the suspension (i.e. the shocks from the lower arms. That way, you will get only the contribution of weight in each scale reading (i.e. the springs will not transfer any load to the opposing corner - which is what they do).

Tweak on a brand new car is not inimaginable, but it is worth checking the chassis first with a straightedge if you have one. Start as above and work you way down from there.

If one corner is loaded more, then to achieve the same ground clearance you will need to put more load on the spring, thus transferring some of the weight to the opposite corner. If all the above tests are clear, then you need to re-distribute the weight around in your car.

One other way you can tackle this is to just balance the car on needlepoints (like the Hudy chassis balancing tools; you don't need to buy them, just make your own). That way weight transferred by spring load is taken out of the equation.

The TA-05 tubs have been discussed extensively in the TA-05 thread for that very reason, I've bought new plastic tubs and the lightweight FRP tub and they both had tweak straight from the packet when they were put on a flat surface. When I converted my IFS-R to a Ver.II I checked that tub for tweak too and it was much better than on the original TA-05 tubs.

This is the problem with molding plastics. If they get pulled of the mold too quickly they'll distort. Are these still molded in Japan or did they move production elsewhere?

I was lucky I suppose but both my upgrade CF and the plastic one that came with the kit (TA05R) are tweak free.

Default ta05 ball differential thrust bearing

Hi folks,

I think I need to replace the thrust bearing in my ta05 ball differential. Will Tamiya part no. 53136 (OP-136) work?

Thanks much.

I wouldn't bet on seeing any IFS-R's before the Ver.II R is released.

Yeah but it's veeeeery expensive at TamiyaUSA.com, and it seems for me V.2 is very expensive, it doesnt include the good stuff of an R. Is it really worth the V.2 vs the v.1 for such a difference in price???

That kit has been discontinued so eBay would be your best bet. We have been out of stock for about 7 months.

Default Wide pitch pulley

Is there any advantage (or otherwise) to using the wide pitch 36T pulley ( 49472 ) as a replacement for the standard white kit pulley. The wide pitch one , has every second tooth missing , and from the side it only has holes for the balls with a rim where the original pulley has other holes on the outer perimeter.

I bought it as a replacement for the rear , but the question applies to front or rear.

Thanks
