I bet as an added bonus they even throw in a soft squishy alloy pinion!

Always wondered where all those recycled cola cans ended up.  Shiny new tamiya pinions!

Here's an unboxing video (ugh), skip to 3:30-ish to get to what's actually in it.

No you cannot buy the BT01 yet (it's not even accessible through their link), but if you're a youtuber and know the show, you can enjoy your freebies.

Bushings, frictions shocks, soft silver self tapping screws...

I really like that it is not another 4WD, but it seems to be very poor straight from the box.

144 Euros on Tamico. Ekhm, Tamiya, are you crazy?

What would be the price you are willing to pay?

Or what is the price for a comparable product from a Tamiya competitor?

Including a detailed and licensed body shell, a motor, an ESC and wheels and tires?

Bought by a specialized dealer with an actual shop with employees (which wants to be paid), not just a web shop, and including 19% VAT? 

Imported by a distributor which also have employees?

@Kowalski86 thanks for sharing.

Seems the configuration options are:

• MR: Rear-Mid Motor RWD (main manual)
• FF: Front-Mid Motor FWD (second manual). This one is a flipped MR with the steering on the opposite end.
• FR: Front-Mid Motor RWD (third manual). Similar to the MR but now with the motor a bit more forward for more front-biased weight.
• MF: Rear-Mid Motor FWD (officially not in the manuals). The car is FWD but now with the weight shifted to the mid-rear. Probably not the best handling resulting horrible acceleration/braking and understeer, but I guess it's there if somebody wants to tinker.

It's a bit hard to see on the video, but I'm guessing the gearboxes do not have a step-seal on its edges (like the TT-01 and unlike the TT-02), possibly leading to dust easily getting inside (like the TT-01). The front diff housing, which is empty and left hollow & unplugged, will become a nice dust/rocks storage tank.

I'm trying to understand the function of parts T5 (manual step 14), which then oddly disappear from the assembly on step 17. Similarly, parts T4 (manual step 12), which also appear to have no function but at least they don't disappear later. They can't be any sort of steering limiter since these are fit to the rear suspension arms. They kind of resemble the TT-01/2 steering limiters, but if this is the case, shouldn't they be on the opposite end?

Now I'll wear my Grinch suit and spoil Christmas.

For me it's a confirmed easy pass. I still can't see this car on any configuration being superior to a TT-01/2 converted to FWD or RWD for multiple reasons. Maybe the FF is slightly better biased but even here on a FWD TT-01/2 you can add weight to the front. Tamiya scores some points for trying something new, but I'm not impressed, sorry!!

P.S. Don't worry Tamiya, you will probably still get my money through your other offerings .

Check price of e.g. TT-02. 

In my LHS, with Pre Painted Mercedes body, costs around 90 Euros. If you do not want fancy body, but something more usual, kits are even cheaper. 

Sorry, even cheaper:

https://zabawki-modele.pl/en/mercedes-benz-clk-amg-2002-silver-painted-body-tt-02-tamiya-47493-19130.html

Motor and ESC included. I can go today and get it straight from shelf.

80 Euros for NSX.

https://zabawki-modele.pl/en/tamiya-58634-samochod-zdalnie-sterowany-honda-nsx-tt-02-15240.html

Both bodies are licensed.

[Aerobert 2326]

In my opinion this is not comparable. TT-02 is a ten years old design, the BT-01 is not even on the market. One is 4WD only the other one could be build to FWD or RWD. Let's see what the price for the BT-01 is in about one or two years.

[skom25 2321]

I agree, but I was bit shocked with price. However, Mercedes which I mentioned costs 134 Euros on Tamico... Maybe my LHS is just super cheap?

It is not fully new kit. I watched linked video and many parts are shared with older, well known kits.

Anytime

I never checked the diff housings on my MB01, but the gearbox was pretty clean anytime that I opened it up. I think this uses the same setup, so you get to enjoy hunting down a 29t 0.6 pinion gear!

The BT/MB cars are meant to be more "scale" than the TT line-up, which I like. It's more in line with Tamiyas philosophy. They're a good idea on paper.

[Kowalski86 4486]

Here's a video of the BT-01 in action, RCdriver makes a good point on the suspension mounts too.

[Elbowloh 1411]

Looks like it drives quite well stock! Surprised.

[skom25 2321]

It has also Pre Cut stickers!

About two months ago, I was called "lazy" when I said that I prefer Pre Cut version. LOL.

It looks basic but quite nice. However, friction shocks and bushings are... 😮‍💨

I know that it is entry level kit, but we are not in 1984 anymore.

Give me pre-cut any day of the week for a body that's good to get run and scuffed up.

I could tolerate bronze bushings, but yea, this is not not on my radsr. Having to buy so many little things adds up.

Interesting video but he doesn't mention the sloppy fit of parts out-of-the-box.  I enjoy watching his channel but has this guy ever given a negative review??

Anyway, like the MB-01, I reckon this model has its place.  Especially if you like to tinker.

BTW, I drove my MB yesterday and noticed some odd anti-steer whilst transitioning from one direction to another.  I discovered a floppy left rear wheel and upon further investigation, the axle shaft is actually undersize by .1mm (4.90mm)  No way to fix an undersize shaft.  Disgusted, I reassembled the car and threw it back on the shelf.

My thought too…..

 

But i gotta say, i am quite excited about this model due to its uniqueness and ff configuration…

[ChrisRx718 4707]

Saw this earlier courtesy of Tamiyablog.

Can't say I'm excited about this release! Seems to share a lot of parts with the MB-01, in fact it's really just a scaled-up MB-01. My experience thus far has not been great with that chassis...

Such a shame because we need the MB/BT to succeed otherwise we will keep getting TT02's......

[Aerobert 2326]

I'm looking forward to this and will buy / build one. After several TT-02 I want to build something different.

It's interesting how there aren't any significant hop-ups listed, just little bits of "bling" and a few shared TT02 parts. On a side note, It's next to impossible to find Tamiya on-road spring sets here in the US.

I'm not in the market for one myself, it's just another sloppy on-road chassis with bushings/friction shocks.

[Sogogi 3362]

I have a feeling that tamiya would make more profit selling those hopups than bt-01 kits….

BT-01 seems to be much more complicated than TT-02, which is very simple and easy to maintain.

If we consider that TT-02B is still very popular, I think TT-02 chassis will be with us for a looong time.

It may look it, but it's actually really straightforward just with an odd appearance. The whole diff assembly and motor mount are two separate units and you simply rotate them / insert them at either end of the chassis to determine the driven wheels.

The worst part I can see about the MB-01 at the moment is the suspended steering assembly. Instead of it being mounted directly to the chassis, it "hangs" from a cantilevered piece of plastic (which has mouldings to replicate a double-overhead-cam engine cover) which is itself bolted to the front bulkhead, with only two screws. The whole thing is quite...floppy. I can't see how even a metal Hop-up would rectify it. This very same piece of plastic can be seen in images of the BT-01, suggesting an identical steering arrangement, which is bad news.

 Part is "D5", see how it 'interlocks' (very loosely) with the suspension tower and is bolted to the front bulkhead.

All those top end racers will tell you how much better grip and flex feel you get from a floating steering link setup 😂😂😂

[skom25 2321]

I think fancy, invisible under body engine imitation will boost performance too!

Tamiyausa already lists spares for BT-01 - chassis extension (you can compare it to MB-01) and transmission parts for FMR layout
