True, but I think for front/back flex you're going to have to bend the motor mount first before that would be an issue. Just add shims if you're worried about it, bring the bar out an extra 1mm from the chassis or something and use a longer screw.

couple questions... started building my ta05 tonite.
this is a casual car. ill only be building it as i get parts.

anyhow here are two pictures regarding my questions.
the chassis and bulkheads are 3racing btw....


ok. in this picture if you look at #1, youll see a gap between the posts and the top deck of the chassis.
i need a spacer. there are spacers on the top of the posts in #2
they came with the chassis. apparently im 2 short. where do you suppose i find 2 more?





and then in this photo, i just want to make sure that the side of the gear shaft should just be hanging like that.
in the stock car, its supported on both sides.
not so w/ the 3racing chassis.
is that normal? or am i missing something.

You should be able to find the replacement parts you're after from 3Racing. If not, Tamiya makes a spacer/shim set that has a range of blue annodised aluminium spacers (and some silver ones) that have 2mm or 3mm sizes included (which I am guessing you might need).

As for the center shaft where the spur and centre pulleys are mounted. That is called a "floating layshaft" and its the same configuration used on the TA05MS.

Personally, I am starting to dislike this floating layshaft arrangement. The spur gear/centre pulley assembly can be pulled forward or backwards by the belt tension on the respective belts and after while because of this stress back and forth under accelleration/decelleration the spur gear holder will wear. I'm also starting to think it might be the cause of some serious belt slipping/stripping I am seeing on my TA05MS with a low wind brushless motor (havent been able to sort this issue out yet).

wow thanks for the quick response.
ill keep an eye out for the spacer set.


as far as the 'floating layshaft' thing... i agree with you. that was my first thought is that over time, it would move around and either excessively stretch out belts or strip gearing...
doesnt appear to be a way around it though

I wonder if theres any way of incorporating the V1 3racing chassis layshaft mount in there?

jet racing also make the blue spacers you're after

if you're really stuck, i *think* those plastic spacers which fit either side of the wishbones might fit in there.

Well from the picture I can tell you that your center shaft is assembled incorrectly. The floating layshaft should not have a bearing on the floating end. It should have a bearing inside each of the two bluk-heads on the supported side. As you can see from the following image, the V2 Chassis includes it's own special center shaft. You cannot reuse the original TA05 one...

The ones you've linked do not have a 1mm drop to them. That is part number 53876 and only comes in blue...

Just an FYI for anyone new to the TA05, a lesson I've learned the hard way.

I wanted to widden the rear track, so using the chart I just ordered a D front. Well got it today and it doesn't fit inbetween the webing there.

So if you want to stay TCS legal can't do it.

Could you use some of those flat roll-center spacers to lift the block. Perhaps it will clear the webbing that way...
