Missed another race this weekend due to illness... But at least I finally got into uploading all modifications I'm using on my chassis.
Here's my Printables collection that contains them:

With them being 30mm I reckon 42300 would be correct.
Yes, but uprights appear to be derived from M-07, which is 1mm shorter. So it may require a shim or axle from M-07 DCJ

It would be nice if the manual + compatible upgrade list was released
CompetitionX channel has unboxing video, where they listed through the manual. I think that release info contained some info about compatible upgrade parts, mostly ones that are shared with XV-02 - differentials, steering, suspension mounts. Double cardan will be probably combination of M-05 DJC swing shafts and M-07 wheel axles.

What I also wonder is if it would be possible to fit the portals from the GF-01 on the GF-02?
It still uses TL-01 uprights, so yes, they should work. But it would end up wider, because GF-02 has longer CB arms.

It seems to be a nice step forward from the MF01X-
It should be, when it costs nearly three times as much 😃 But you get a proper rally car for the price, unlike MF-01X
It looks like there's a lot of potential for it to go even faster. The stock setup seems to be a bit jumpy and it understeers quite a lot on this tight track.

The gearbox looks great! Do you think it would be possible to move the spur a bit lower? It might reduce motor movement necessary to adjust gears. It would also move the counter gear a bit higher, further from the motor, so you could add a wall to fully enclose the gearbox.

I don't have an M-05 ball diff (I built mine using FF-03 outdrives and Sakura diff gear), but its gear is about the half the width of the stock diff gear. So it's not necessary to modify it, however, keeping the transmission compatible with either TA02 or M-05 gear diff will allow you to use other diff options, like R-evo differential case.
On 4/19/2024 at 5:34 PM, ThunderDragonCy said:Still, it's a decent first look. Need to get some 1510 bearings. I can push some 1050 bearings into them and run the ff01 diff for now.
M-05 solves this by using plastic bushings that fit 1150 bearings, in the case that gear diff is used. It's part of uprights tree (51393, 51425, 9000815), so it's quite cheap readily available option.

@Pylon80 Thanks! Awesome and very helpful info. I'm surprised tbh, they appear thicker on photos.

That looks cool! It's bummer that Tamiya didn't release some retro bodies on these chassis. It looks like it's been made for that.

Are you thinking of making your own?
Yep, I'd like to give it a try, although it probably won't be easy. Thanks
@Pylon80 thank you, I had a similar thoughts, these wires can be sourced quite easily and cheap from hobby stores, but I can imagine they won't be easy to bend the diameter used on M-05.

I can get a measurement for you tonight. Actually I believe I already did and posted them in "the postman brought me" for the benefit of another member.
Thank you!
I found your photos of the assembly manual, that's extremely helpful as well
Unfortunately, I cannot find diameter measurements..

Anyone who owns M-05 stabilizer set, is it possible to measure what's the diameter of wire on all pieces? Thanks

Does somebody know (and/or have a picture) of what a full hopped-up FF-02 looks like?
I wanted to suggest M-03R (silver or blue metal plated chassis) as an inspiration, but when I searched for some pictures, I found @Juls1's build
Looks like there's every M-03/TL-01 hopup available, except for the most recent sealed gear diff update
There was also a similar metal plated chassis for M-05/V.2 and 3racing alu/carbon extension to 257, but calling that FF-02 would be probably stretch 😃

Almost Citröen 2CV style, there!
Yep, that's what happens when you run dirt settings on a higher grip surface 😃 I run stabilisers on my main car, but that's not an option here (yet? 😁)

I skipped the last race due to weather, so first race of the V2 was this weekend. And it was quite successful. Well, except for another broken front arm. Luckily I have printed couple of spares. I got TL-01 hinge pins for the future interation, which should help to hold the printed parts together .
I know I should've used firmer dampers on this surface, but I love how it leans into corner 😃

Browsing through the Internet, I found an interesting post on Xitter from 2020. I wasn't the first to try convert MF-01X to mid-rear motor setup. Using the rear half of TL-01 was an idea I considered, but I didn't like the limited gearing and exposed motor. Nevertheless, this conversion is very well done and looks great.

Right, I think TLR were making a carpet version with an oil-filled gear diff and a clay version with a ball diff, on one of their buggies.
X-ray does that too with XB2

Interesting about the different part number. Perhaps different material, same tool?
I'd love to know that too. And if it's a different material, is it better or worse? Or maybe there's just a little difference in tolerances...
12 minutes ago, Pylon80 said:I think what it does is make the diff a little lighter at the expense of a little bit more play/less smoothness?
My guess is, that two gears, will cause less increase in locking force at higher left/right difference speed. Alternatively, similar to Tamiya, recent buggies use ball diff again, which has more or less constant force regardless of speed difference.
Funnily enough, years ago, I found that my rally TB03 was faster with ball diffs than gear diffs. Back then, I though it was because of poor quality of 3rd party gear diff (it was before TB-04), but it seems, that there's something good about ball diff on low traction.

The XV-02 diff actually uses the bevels from the TRF420 diff (as I recently found)
I thought that, too, but XV-02 uses a different PN (10015174) and TRF gears (51567) aren't shown as compatible in the parts matching list...
I recently found out that buggy racers run only 2 small bevel gears on dirt. Interestingly that's exatly the setup of TT-02 metal differentials, although I'm not sure what's advantage of that solution

found this video that compares TGS Vs XV-02 gear diff. The parts are not interchangeable...

@BuggyDad thanks for notice that the video doesn't work anymore. It's from this channel, that also posted interesting video with hopped up TA01

We didn't get to an answer then, but in hindsight @Honza's suggestion of something to try is, I think, exactly what you've ended up doing (although I can't see the video he linked to and I can't remember what was on it).
Yep, it's exactly this product. I don't know why the video went private. I made an update in the topic.
It's cool that these old Tamiyas got option for more modern diff design. @wtcc5 confirmed that it should work with most Tamiyas that use same diff internals.

Well, I dried out the black PETG filament and went to Prusa default temperatures at the same time, so not scientific and I don't know what improved it but something did.
It could be both. High temperature can cause excessive stringing, which then causes filament to adhere to nozzle and deposit randomly. Same with wet filament, that causes bubbles. Good telltale of wet filament is purge after filament load.
The IKEA cabinet looks great. I still haven't got into making mine 😃

But who know, they could be a different module but same outside diameter and bore and actually fit. I will give it a try!
If they are coarser module, they might be even stronger. In the worst case, you can fit the entire differential.
-
TB-04 or TA06 steel bevel set don't fit. And XV-02 has different bevel gear set from TRF420 and derived models.
Early oil filled diff in TT-02RS used #51144 TG-10 gear set. Since XV-02 diffs are similar, maybe that could fit? Unfortunately that PN is not present in any Tamiya matching set, so I cannot confirm it.

TL01 MF01x compatability.
in General discussions
Posted
Only the basic gear set is taken directly from TL-01 - you can use speed tuned gears, but the little spur gear is reversed on MF-01X, resulting in reduced teeth contact with the counter gear, caused by slightly different teeth geometry.
The rest of parts is more M-05/6 - diff internals, outdrives, suspension, even most of inner gearbox shafts.
Diff cups are also shared with TT-02S - there's also a reinforced part available.
