With the TL-01 being possibly my least favourite Tamiya chassis I'd hoped for a more radical dissection, losing as much as possible of the brick section between the gearboxes in favour of a carbon base plate & top brace - however anything you can do to improve it has got to be a good thing

What's the provenance of the carbon fibre shaft? I have to ask after seeing someone on TC make their own & seeing it shredded after a short run; tent poles & fishing rods don't have the torsional strength required ...

I have thinking of removing the middle section of the chassis in the past, but I think it will look rubbish and will be a sort of TA01/2 chassis in the end.
It would be bulky as well.

For the carbon, I did go for a rod instead for a tube section, but Tamiya did actually made hollow carbon shafts for the TL01, #53322
In my head a rod will be stronger than a tube, if plane can use them on wings I think it will work in a transmission too.
Here is the Tamiya item

Carbon propeller shaft was #53323, not intrested to pay around 100 dollar for one of those when I can make it myself.
Again here is the Tamiya propeller shaft

As for now, I don't know if this will be a runner or not.
So for a shelfer, carbon won't hurt anyway

You can make a frp version like I did for a m01.

I have done the same with my M01 which I converted to M02.
The plates where made in styrene.

Suspension done. Also installed the bumper.
Since I had 3 cvd axles and 3 dog bones, the fitment were obvious for me.
CVD up front

And dog bones in the rear.

Next up was the shocks.
For now I'm using stock TL01 shocks with the medium # OP.163 springs.

Battery holder fitted and while I did that I did test if my 3d printed battery holder would fit, which it does

Since I had new aluminium wheel hexes and pins laying around, I fitted them too.
TopCad if I think..

And the 2 piece wheel fitted perfectly.
Will paint them up like goldfish did

Since I'm running cvd's up front, it would be stupid not to use the extra steering angle they can handle over stock.
Those two small nubs or ribs will have to be trimmed down as they catch the c-hub.

You can see here they act as a limiter.

Meanwhile i wait for some adjustable turnbuckles I did go ahead and made some tie rods to avoid the wheels flapping around

Servo and tie rods fitted.
The electric bits inside the servo is removed so this will only hold the steering for now to make it look complete

I'll keep you posted on the progress

Great progress mate

Lovely ugly chassis. You give it an interest for me.

The direction of the fiber wind is very important. Fishing poles and kite spars made to resist bending will have the fibers at 0 and 90 degrees in general. This is almost useless for torsion. For a drive shaft you want the fibers wound diagonally at 45 degrees (spiral wound).

All other things being equal, a rod (solid) is stronger than a tube (hollow). But if you consider the winding, a hollow spiral wound will likely be stronger than a solid straight wound if used as a drive shaft.

Ugly is the new hype you know
There is several chassis from Tamiya that are based on the TL01 bits, some look better and some are more complex.
One reason I like it is beacause it's so simple.
