Finish!





That's really a light car! Never had a Tamiya 4WD that light...

With my setup I had to add 20g on the front (2x10g 419 weights) to make race weight of 1320g.

Still need to test the car, if too much steering will probably switch to 5g on front and brass suspension mounts (~15g+) for the rear.

This chassis tends to be underweight, which really surprised me. It seems, Tamiya made his homework, as this kit is the first one, I would say, no special weight reduction actions needed.

Definitely a new weapon for 17.5T spec class...

My TRF420 is 100grams underweight, i expect this car won't be any different

Only their shaft TB Evos were on the porky side. Lot of steel driveline components.

Default Tweak

How do you think tweak will be dealt with between MS and MSX? I have a dual vertical topdeck TA07 and tweak is noticeable, as I tend to crash a lot... If you twist the chassis, do you note a change in tweak, or does it center each time?

With hard or frequent crashes there is of course higher chance of tweak, that should apply for both conventional and vertical top decks.

When I race I always loosen my chassis to set it flat between runs.

Default Top Deck - tweak resistances

Agreed, this is what I do, too. Regardless, even after it's detweaked, with my TA07 topdeck, i give it a "twist", and gone is my setup. Wheels would not anymore lift evenly. I wonder, if one of the two top deck designs is better for repeatability?

the important question: is the x faster than the ms without x?
I am waiting for exact scientific results under standardized parameter!

Well, had to pull the trigger as rcmart offers them at a really competitive price... That will be a good benchmark against my own design, as I want to use a similar yet different drivetrain.

Default Design flaw

There is strongly an update of the new TRF420 parts needed...
They are way too short and not even compatible with Tamiya's own shells.

What has Tamiya thought, while designing it? That everybody is only using this freaking shitty bubble canopy racing shells???







Has a anybody experienced the same?
Is there a solution?

The old B-parts work only for rear, as the front has now extended hexes...

Yes, I know, but they are way too fiddly and flimsy...
I have them in my spare parts box.

But thanks for the hint. I hope they update the B-Parts.
