Default Tamiya BT-01 Chassis (RWD/FWD)

New 2WD BT-01 TC sized chassis offers choices of FWD or RWD drive system.

First car kit on this chassis: 58733 Toyota Supra (JZA80) (BT-01)

New BT-01 Chassis
Length: 397mm, width: 185mm. Wheelbase: 257mm / 251mm (*).
The 2WD BT-01 chassis gives a choice of two types of wheelbase (*), and front- or rear- wheel drive system.
Without removing battery pack, motor and R/C equipment setups from the center frame, simply change attachment directions of final gears and steering linkage to switch between front- and rear-wheel drive; front (FR) or midship rear (MR) motor position can be chosen for rear-wheel drive cars.(Six setups are available in total.)
The 4-wheel double wishbone suspension features symmetrical structure and friction dampers.
Unitized sections such as motor mount, final gears and suspension facilitate ease of assembly and effective maintenance.
Many Hop-Up Option parts for TT-chassis cars can be used to fine-tune setup.

Looks like it shares some parts with the MB-01.

Indeed it does.

I can see what Tamiya are doing here, very cheap RWD/FWD chassis as a body holder for touring size bodies. And in a sense I'm pleased to see Tamiya offering a "scale" drivetrain for those bodies rather than 4wd.

But I struggle to get excited by it. MB-01 that is is based on has very limited steering, this is probably the same. They haven't even bothered to launch it with a brand new body set.

It probably won't even be much cheaper than a 4WD TT-01 or TT-02.

Cool. But you won't be able to get one for months.

I get the sense from releases like this that Tamiya is carving out a "Duplo" level market niche.

It's really hard to beat a car that's all of like 25 parts. That said, I think the BT-01 is a better car. We'll need to see though.

What makes you think the BT-01 will be better?

Looks like out of the box adjustable toe front and rear maybe?

Losing 4WD will have a far bigger performance impact than that.

I think you guys may have to compare it with the old FF series chassis for a fairer test.

I can't speak for the BT01, but its smaller MB01 brother has better steering out of the box than the TT02.

I guess let's compare it to the FF-02 then (basically an M03 on steroids), the FF-03 was more racey and came with little things called ballbearings and oil filled shocks iirc.

I have an MB-01. The steering limiters on the arms severely hampers the turning radius and the car has garbage handling compared to an M03. I'm not sure how you're comparing the steering of a 2WD m-chassis to a 4WD TC.

It comes with droop adjustment. It's steering sits on larger pivots and isn't dependant on step screws.

We'll see. I need to pick one up and try it out.
