Sorry I meant 2.5 of course. That is common on many custom designs (Krazed, my own designs, others). With slots in the right spot, you can have the chassis soft enough, despite the bulkhead mounted lower A arms. Believe me, it has worked for my h2e five design, too.
And yes, dont forget to make a thinner topdeck, too.

Thin top deck is okay because of using button head screw

A 3mm chassis would be perfect on black carpet...My 2.5mm chassis needs a center spline and corner posts to get consistant, eventhough it is a different car....
Corally cars have always been too fast...Good Luck...

Quite the thing of beauty. It might fair well
on carpet, but I feel like the chassis is a little too thick 3.00 mm lower and 2.9 mm upper for carpet racing. This car was designed around foam touring and Corally was a formidable contender in this forgotten touring category.
make sure you have spare arms for that bad boy. They used to sell arms in 8 packs lol. They’re like glass.

Finished rebuilding my daughter's first rc car which she almost TQed in Tamiya Asia Cup back in 2011. This time will ambitiously try to win our open/modified touring class. First shakedown tomorrow

Default Pro 4 Rattling Drivetrain

Hello

I recognized a rattling noise from the drivetrain. Then I replaced the old stock bearings with Yokomo Ceramic Bearings. Now there's a slight rattle.
I thought the rattling was from bad bearings(?)

Can fast and slightly harsh driving cause drivetrain problems? (I mostly run my Pro 4 to do the Fastest-Lap Challenge at my school yard track)

Thank you

Did you try another set of wheels? Wheels could be deformed maybe? Drive shaft straight? Lost shims during servicing?

From being a skeptic, my driver is now a believer. First shakedown with a 5.5T motor, her TT01 did 14.4s vs her fastest modified car (14.3s) on our low grip technical track. Excited again

Interesting, that's a lot of motor, power should be no problem with that! Did you find the gearing suitable?

What did your driver think about the aero and weight of that body? I have that Toyota Celica Group 5 body and enjoy running it, but it different feel compared to other Tamiya bodies such as the NSX.

I used 22/61 for FDR of 7.2. Celica body runs nice and straight albeit a bit heavy. But for a low grip track the extra weight provided extra traction. Wanted to run a 251mm short wheelbase that's why the Celica.

Maybe the drive cups that hold/support the main shaft aren't straight.
