Nice MTC2 in blue. To be honest, I was hoping Tamiya would throw in more of their own flair. At least they still insist on using plastic arms and hinge pins

Edit: saw wrong, its pivot ball suspension

What do you mean by hinge pins?

I'm betting I couldn't get one in Australia for under $1500 Aussie Rupees. I'll be shocked if any Aussie shop will stock it, unless you special order it.

Will see how it runs in TITC 2024. Surprised, a kit far different from the prototype being tested last year. I'm a Tamiya fan but not a fan of this copy that does not even bring anything new to the table. Might as well copy the latest (i.e MTC2R) and not the 2020 version

I'm happy Tamiya is at least still in the ring.

And if it had adjustable 4link everyone would call it tAMXiya

No hinge pins .... pivot ball suspension.
Looks like lots of room for Factory upgrades. Just wish Tamiya's werent a house payment to own in the States.
Good to see though theyre still thinking hardcore racers.

I'll have to pick one up possibly for TCS GT1 and maybe use it for VTA (matches the new spec motor color!) in the off-season.

Looks like no aluminum chassis is included with the kit?

Well Dan, it appears they listened to you,., those TA08 arms didn't have the right "geometry" for a TRF car.. so they redesigned them lol. I for one appreciate the plastic lower arms. Breaking carbon arms is not cheap.. unless you are running a 3Racing Cero.

More interestingly.. the XM-01 Pro answers a proper M Chassis 4WD rallye chassis, versus the MF-01X. Now I know where to put the Fiat 131 body 😉

Joel, No one will ever be happy with Tamiya. If they continued with the 420X style, feedback would be Tamiya is just releasing kits. They finally changed to lower and upper arms like MTC2 and now it's.. they copied A, B , C Brand etc. All current 1/10 chassis in truth have copied Awesomatix. The only thing they haven't copied is their shock design.

At the end of the day, Tamiya only cares for feedback from its racers in Japan.
