Pretty tough to compare apples to oranges. Unless you're wanting something unique (nothing wrong with that), I'd rather get a TT-02 which is probably the same price point as the BT-01. I'll buy an BT-01 in the future if it comes equipped with a body that you can't buy separately.

A big reason I didn't buy the MB-01 mini since I already have the older minis and an M07/M08.

I was rushed for time with my previous response. I've driven my MB-01 in its RWD setup with a decent metal servo horn (the kit servo saver is terrible), the steering feels better as it uses ballbearings.

It does handle worse than previous entry level M-chassis, both due to the weight/bulk of the chassis and the weight distribution.

What you and others have said about the turn radius is no joke. My MB01 just gets driven about on the street, but the limited turning combined with its weight (its only slightly lighter than a TT-02), has been an issue. I have to steer with the throttle like I'm powersliding an old buggy around!

We'll see. I need to pick one up and try it out.
The large pivots on the MB-01 pop off very easily. I don't consider them a win.

The steering only uses ball bearings if you upgrade them. The kit uses bushings.

Mine popped a pivot as I was just driving on the road in front of my house, I didn't even tap anything.

I like having the option to install bearings around the steering bellcranks without a hop-up.

I’m going fully salty on this release!

For a while now we Tamiya fans have complained about our favourite rerelease bodies coming on TT02 chassis.

Tamiya as a result has decided to punish us insolent westerners with the fabulous all new BT-01. 😂🤣😂🤣

By pivots you mean the balls you press into arms? If so, they’re the same as TT02. If you push them in per manual you should be ok. If you compress too much then they will pop out. Easy fix is the low friction metal ones from TT02.

That's what I meant yea, either washers or low friction balls work, I ran a set of low friction balls in it after that and I didn't have it happen again. A nice side effect of the metal TT02 balls is that they reduce slop too.

The more that I look at this chassis, the more confused that I am. The TT-02 does the whole "cheap touring car kit" thing fine enough, it has a better steering angle than my MB-01, and the TT can run with other basic touring cars on the market.

This seems more niche, I can’t see the FWD setup competing in a FWD class, and without steering angle mods it'd be a poor drifter. It'll have to be really cheap (or play up the "scale" aspect) to sell.

Stop looking at it and wasting your vision. 😵‍💫 no good will come of it

Hadn't realised that this also offers a front-motor-rear-drive option. I think that's a first? Certainly adds to the "scale drivetrain" appeal of the chassis. If I was buying a Supra to drive up my street before putting on a shelf, I'd want it to be in FR configuration rather than a 4wd TT-02.

I want to see how the driveshaft passes by the battery in that configuration.

Battery over the top.

Obviously terrible for CG but this is not, and never will be, a performance chassis. It's a cheap, semi-scale-accurate body holder.
