Congrats on your purchase. Looks fantastic. I have a question: What is the overall width of the chassis? Thanks c'',)

Wow- if that is reading 679g that’s 40 grams heavier than the evo7 I have as a beautiful shelf queen! Was too heavy! Would be interested in a review In performance against something like a TRF420. Only chance of being near class weight is with a shorty pack.
or is the weight 619 g on that scale above?

Quick note: After assembling I noticed some binding in the rear gearbox, I added a 0,1mm shim in step 6 as pictured here – that eliminated some play that could push the bevel gear into the differential.
Another potential source for binding are the polycarbonate dust covers – they can touch the diff housing in the rear. I made a small cutout on that side.

Nice looking chassis! Is there any loss of longitudinal rigidity around the spur gear? I'm asking as I've noticed that the supports that are on either side of the spur gear is not bridged by a top cap (like on the Evo7) and it seems that it's either the chassis plate or the spur shaft to resist longitudinal flex around that zone. Although the Evo7 also has this discontinuity lengthwise, they're located close to gearbox area where the effects of bending are less significant.

Disappointing that they didn't bridge it with a top cap like on the evo 7. I wonder if the part from the evo 7 would fit if you get get hold of one.
I hope tamiya releases it as a hop up option, my biggest fear is the chassis splitting there in a collision.

Just finished building mine, and yes there is loads of flex around that area where the spur gear is.

Just by photos, the chassis (esp. being carbon) should be okay in a hard frontal impact, and most likely the spur shaft and bearings would take the hit.
They could have made a bridged top cap with offset mounting points and slightly shorter top decks. Only time will tell if it's an issue or not.
As far is as I know Tamiya has stopped the strategy of offering hopups for Evo specific cars since as far back as the Evo6, likely due to the much smaller production quantities compared to their other RC lineup. A run of MS version of kits is more likely than hopups.

Anybody used it yet? I will be on Friday, low/medium grip carpet, stock setup.
The stock front end seems quote narrow, it suggests the e block with the inserts inwards 1 notch, which i assume is what on the old system would be a D block.
I've always found F to be the best on my 419xr.
