@Alex97 wow, that was quick! It's unfortunate that there were such issues. It's weird that reviewers didn't mention this, especially this one:

Nothing is labelled in the box, the screws/hardware packets don't tally up. 

The unboxing video linked earlier has shown traditionally labeled hardware bags. Could yours be some bad batch?

Hopefully it won't stop you from finishing the kit

Btw, would you check PN of wheel axles in the manual? I'm curious if they are compatible with existing models

• Spacing for the arms is impossible, they call up different sized spacers however the codes for each part isn't on the back and if you build it with the supplied spacers it won't go together. I ended up using a range of 3mm spacers to get the correct "packing", this did allow me to get rid of any play in the arms.

 

I appreciate youre more of a 'useable performance' guy than a shelf builder like me, but my SRX was exactly the same. I know Tamiya were being cowboys in the first place by bodging TRF arms onto a humble TT02, but they would have been better off telling me in the instructions 'there's a bag of shims, there's the arms, sort it out yourself' rather than 'suggesting' a specific shim lay out.

 

Hope you get it sorted mate, Tamiya need a win, the BT/MB-01 seem terribly received......

@Alex97 Thank you for the photos and the report of your first impressions — that's wonderful and very exciting.

Still no manual online?! My patience is growing thinner!

My Tamiya shipment has been sent but has not yet arrived at Redfin Models. It might come tomorrow, failing that Tuesday. I have some annual leave coming up so I really hope the stars align!

I'm 50% through the build so there's still time. Tbh that's been my only issue so far, I'm swapping out the Tamiya screws for cap heads where I can as it's just better. It might of been me just misunderstanding the manual. It's not a biggy and I'd no doubt of ended up shimming them anyway..

Thank you so much - what a great service!

[Alex97]

Round two was much better -

The standard Tamiya shocks which went together as expected and everything was plain sailing. The area for the the electronics is very tight and not helped by the aerial post, I did try the manual setup however my receiver was too tall once the cables are plugged in. I think a lot of people are going to have this issue. My suggestion is to remove the aerial post and make as much room as possible and stick the ESC directly to the chassis like I've done.  

Looking back through the manual I did use the wrong spacers early on, not really a biggy as I replaced them with shiny blue ones. An error from me, not Tamiya. 

I still need to tidy the wiring up and trim the under shell however it's 95% there. 

 

Overall thoughts- it was an ok build, compared to the likes of Team associated, X-ray and Tekon Tamiya are way behind in how they pack their kits and in a "pro" model I expect more, having all the hardware mixed really doesn't help, however once built this isn't really an issue. 

They've tried to carry as much of the XV-02 over and they've done a good job, being able to use a slipper clutch or centre diff is very nice and something of a first for a M-chasiss Tamiya. There's also a range of other upgrades which will bolt straight on. Compared to the M07 the quality is on par however the overall M07 design is better in my opinion. 

I've added some extra blue bits but considering the price I'd like to have seen blue hardware included as well as a few upgrades to justify the price tag. 

Saying all that I've got a soft spot for M chassis cars from Tamiya (expect the MF01X) so I was always going to buy one and once it's all up and running I'm sure it will put a smile on my face. Would I buy one again, yes.

@Alex97 thanks for the manual. Looks like it uses same TRF417 wheel axles as M-07, so there's still chance that uprights will fit the 2wd Tamiyas to make a rally version  but I wonder why Tamiya lists M-03 universals as an option, when they are 1mm longer.

I wonder what went wrong with the hardware bags, I've never had an issue, it always has been lego-like experience.

The chassis is definitely a step-up from MF-01X and looks great. Still, I'm not fan of XV-02 design due to upright battery, I think there are better designs for a 4wd M-chassis.

Unfortunately that's how Tamiya is with prices nowadays. If they added more blue stuff, it would be in R kit range with minimum performance gains...

I would like the opposite - a cheaper version similar to M-07/8 - plastic CVA shocks, CVDs only on the front axle, I wouldn't even mind open diff on the rearaxle. Just keep the good plastic. And maybe throw a rally body on. That would be awesome replacement for MF-01.

 

Btw, can you check if large rallyblocks fit? A lot of people run full size tires on minis, if body allows it, since they perform a lot better, but it looks like there isn't a lot of space around the front axle.

It's not looking good -

 

I reckon if you pushed the wishbones forward you'd be able to get away with it however you'd need to bring the rear end in as well. Edit, yes I know there's an extra spacer on the left shock bottom.

This was a slight concern when I first saw these appearing.

I’m thinking that maybe using a shorty battery might leave enough room behind it on that side of the chassis to fit a receiver there ?

I use a Shorty in my XV-02RS and is a nice snug fit and cobbled a retainer of sorts out of some Lexan off cuts to stop it sliding back that’s been working well as the RS doesn’t have the chassis cover like it’s more rally oriented brother. Theory also being there to keep as much weight forward as possible like a 1:1 to let the rear drift.

Like you I’m a sucker for M chassis and seeing as it Tamiya’s offering of a nice 4WD version in a long time, (I could never bring myself to pick up the MF01X)  it’ll work out somehow.

That intrigues me. Is there a specific reason for that extra spacer on the right fronr damper or the missing spacer on the left front damper?

It calls for a 1mm spacers, I suppose 2mm on one side counts? 

 

I noticed when I attached the shocks that I'd used a 2mm rather than a 1mm so they were kicking out. I removed one side however I must of forgotten to remove the other. I've actually run out of 1mm spacers so until they arrive I'll use none. 

 

One surprising thing is that they've given you mounting points for an anti roll bar however, they haven't included it on the setup sheet.

Strange it isn't mentioned with the hop ups. Have you scanned the hop up qr code? Maybe they mention more hop ups there than in the manual?

Or maybe only the out of production and nowhere to be found M-03 stabilizer will fit 

[ChrisRx718]

Finally pulled my finger out and started painting the body shell for my XM-01 today, I expect it will be with my hobby shop on Tuesday. Then I have next Monday and Tuesday as annual leave, so I can build it!

Although, it's questionable whether the extra bling I caved-in and bought from Plaza Japan will have arrived by then... I only ordered it on Wednesday.

[chris.alex]

Do you think it is possible to use the XV02 wishbones, shafts etc in order to get a larger track width? Could be beneficial especially if you want to use tc cars wheels.

The suspension mounts are same, so it shouldn't be an issue. However, there aren't many options of 190mm wide, short-WB bodies.

Speaking of suspension mounts, looks like Tamiya is taking notes from the community - I've seen something similar to A6 parts sold by Embie racing as a tuning option for XV-02 😁

I do have one on my M03 so could give it ago. It just seems odd that they made a conscious decision to add the mounting points on the wishbones but missed it off of the setup sheet. Perhaps they'll release a road version to join the popular MTC class so we'd see it then.

I'm thinking of the Land Cruiser that I bought many years ago as a backup for my GF01. But since the original Land Cruiser body is still in service, the spare body is free for my future XM01. Could work with the 210mm wheelbase.

I'm happy to measure up if that would help (as long as it's 239mm wheelbase)

Same here, I'm not much of a hop-up guy, I'd just like a decent chassis for a change with a bodyshell/shocks/bearings. Considering that both the MB01 and XM01 share a lot of hop-ups/engineering with other models, you'd think they'd be cheaper.

[Alex97]

Wiring kinda sorted out. I also printed a spacer to fill the shorty gap. As it stands it currently weights in at 1300g, this is without the body shell, centre diff fitted and in the longest wheelbase. 

I'm surprised as most M07s race at about 1250-1300g, considering all of the extra 4wd parts I'd say that was pretty good. 

 

[ChrisRx718]

What setup is that @Alex97, 239mm?

Looks smart. I bought a Justock but returned it because it won't run 3S if I fancy it. I've got a replacement Hobbywing 10BL60 coming, hope that fits...

[Alex97]

Yes. I reckon the 10BL60 will fit nicely. I've got a 1080 G2 in mine and there's just enough room. I would suggest removing the aerial post and trimming away posts for the ESC mount. If I was building this again I'd try and fit my ESC and RX before I started building the rest of the kit as it would of been easier to remove bits from the chassis without everything else being attached.

What's F/R weight distribution? Looks like all the heavy components are in front of the centerline, so it might be usable as a FWD.
