Nice one! Mine has some mileage on it but it’s in decent shape. Presently sits on my Top Sabre S4 Mini

sakadachi 03-13-2021 05:03 PM

Thanks, I was away from RC for a couple of years and recently noticed these Cooper bodies cost a fortune! I'm glad I still have like 5 fresh ones I bought long time ago. Going to keep them locked up in my time capsule for later use. LOL

Raman - I love my TOP Sabre Mini's too!

I really wish Tamiya would do a re release of coopers!

Very unlikely to happen as Tamiya no longer have the licence and I can only assume the cost of renewal is too much for them to consider.

Which is a shame because there is a big market for Minis and all things BMW.

I have a M01 NIB I bought from a guy a few months ago for only $300. I wasn't sure if he was aware that they usually go for double that price, but I just took it off his hands and placed in my NIB collection.

m04 servo mount (applicable to m03 too)
 
Been racing my m04 and something never quite sat quite right with me about how the servo is mounted.

I followed instructions and used one of the self tapping screws and a washer on the servo to mount it to the little servo mounting block.
https://cimg1.ibsrv.net/gimg/www.rct...da08eb2445.jpg
But the screw is way smaller diameter than the hole in the servo ear. Basically if I don't crank it down really hard it is at risk of moving and becoming misaligned. This has happened already once where one screw backed out a tiny bit and left the servo free to move a lot in each direction.

I would use the rubber grommets that come with the servo to take up the space but the instructions do not show this and also when I did try the rubber grommets the self tapping screw is not long enough. I tried with a longer self tapping screw with the grommets, the thickness of the rubber made the servo sit too low in the chassis so the arm was contacting the chassis.

Do other servos use a smaller mounting hole? I've not seen this dimension listed on the servos specifications. Is there something else I'm missing?
https://cimg2.ibsrv.net/gimg/www.rct...65cf016ecc.jpg

The servo is a spectrum z590.


Thanks

Most servos have a similar sized hole. This is normal. You can get aftermarket screws for this though:

1up Racing ServoLock screws.

You can also get generic "servo washers" that do the same job and are a lot cheaper.

These are a fairly recent invention but make mounting a servo so much more reliable.

Ah, ok. So something like this:

https://cimg3.ibsrv.net/gimg/www.rct...8144ef9d82.png

and then just find a flat head self tapping m3 screw to go with them.

monkeyracing 11-06-2021 10:25 PM

I use M3 screws with generic hardware store washers under the heads. Works. Those mounting holes do look a little large.

Have not been able to find the old S-Grips (TAM53254) for some time now. Have they been officially replaced by "TAM54995 (60D Super Radial Tires M-Chassis/Soft) and how do they compare?

The old S grips should still be available.. probably hard to come by due to supply chain issues.

This is what I got from Tamiya a while backIt’s a step softer. They have a narrower temperature range and will wear out faster in warmer track conditions, but will have a lot of grip on medium to low track temp conditions. The standard S grips have a wider temp range. Longer wear cycle too.

Xtracrispy 03-09-2022 01:06 PM

On asphalt, would it be better to run S-grips all around, or consider the H-grips in the front for a FWD car?
My thinking with the harder front is to mostly to take out some twitch, and have them last longer since the tires are doing double duty. Not sure if the TCS H-grips have enough traction though.

museguy 03-15-2022 04:40 PM

Hi All,
Are the Tamiya Mini Copper and VW Golf Mk 1 body shells still available?

I can only find the part number for the full kit, not the body shell alone, Tamiya 58438 Mini Cooper M-05 Chassis Kit - Body shell only

Also is the Tamiya Volkswagon Golf Mark 1 body shell still available? Tamiya 47308 Volkswagen Golf Mk.1 M-05 Chassis Kit - Body shell only

For both the Mini Copper and the Golf I can only find aftermarket body shells.

Thank you ! Very much appreciated.

gigaplex 03-15-2022 05:13 PM

Mini Cooper, definitely not available. Tamiya weren't able to renew their license.

VW Golf Mk 1, I'm not 100% sure but I think they're discontinued too.

Nerobro 03-16-2022 09:17 AM

Team Blue Groove repops them. They're not full tamiya sets, but you can find them on ebay.

EDWARD2003 05-06-2022 06:33 AM

Thank you in advance.

Can someone do me a favor and measure the distance (center to center) of the two mounting holes.

CTRJ 06-16-2022 08:51 AM

I just bought a used M05 Pro V2 with the clear plastic dampers. Can you all tell me what spring set I should buy for tuning options? Also what tire combo would be good for black carpet?

sosidge 06-16-2022 12:02 PM

Look for the older style short springs. #42168 is what I used. Tyres will depend on the track, best to ask locally.

Shock tower looks reversible for low cg shocks...Nice...

The mini shocks are already pretty short. You'd need something half the size to fit with the tower upside down.

bertrandsv87 06-16-2022 07:32 PM

Maybe the ULP shocks built with short ballcups will fit on the first inside hole, in case the original shocks are not available ...

M07R
 
Anyone know where I might find a M07R kit for sell?

Autostrada048 09-17-2022 10:32 PM

I just love the M01 so much. I wish Tamiya would remake the original M01

Hi All,

I have been thinking about jumping into the Mini realm and was hoping someone could give me a few pointers.

What chassis is good for a mini beginner such as myself and what are the essentials required for it?

thanks guys

Hyde 02-08-2023 10:03 AM

I created an m01 m02 Fcaebeen group. Join it please so we can discuss this awesome chassis and show off your build

M02L tech racing, with other Tamiya, Tech upgrades. More mods coming soon and some custom stuff. This thing is basically a mini TA03R.. things a blast. I wish I could find a carbon chassis for it

sipaboy 09-10-2025 12:29 AM

Getting back to the M- chassis. I started this thread years ago. Building a M07R . Hoping to start racing Mini .

M07 and M08 got their own threads, though.

Question for the TCS racers who used to stiffen up the diff with blue-tack, anyone got a photo of hoW much and where in thediff it went?

I've locked up diffs with blue-tack before which just Involved shoving as much in that fitted, but the rules at the track I'm going to run at say:

- using the Tamiya kit diffential components only
- Oil type sealed diffs are NOT permitted
- Ball differentials are NOT permitted
- you MUST retain functional diff action at all times

which lead me to remember the blue-tack method from the M03 days except I don't remember lhow it went to get about 80-90% stiffer.


bertrandsv87 04-16-2026 11:48 AM

Ofna diff lock lube is the best...Limited slip diff with lots pull out of the corners, no wheel spin...Works on gear diffs, ball diffs, slipper clutches, etc....

Find some silicone earplugs and just pack the whole diff with them. Much easier to deal with than blu-tack and will make the diff very stiff but still functional.

Have you actually been to a track or an RC shop in the last 20 years Bert? Ofna have been out of business for ages.

Ofna out of business does not mean their products are any worse than anybody else's. You just have to find it on ebay or something or you can try energy suspension polyurethane bushing grease($18) for more diff action than the ofna diff lock lube but still stiff enough to stop diffing out... Bert Knowledge is power !!! LOL !!!

It's not on eBay or anywhere I've seen. Being out of business for years has made it unavailable.

bertrandsv87 04-18-2026 04:35 PM

You have to keep looking for over three months on ebay to find someone willing to sell his stock just as I did a while back : the world does not revolve around you....ok...If you really want it, you'll find it...Life is hard. Wake up !!!

That's your advice to someone who wants to fix their diff now? Wait for months hoping for a discontinued product from a dead company to randomly appear?

bertrandsv87 04-18-2026 05:00 PM

Use the available energy suspension grease now while still looking for the ultimate Ofna diff lock lube. Take it or leave it...Stop crying !!! Lots of cry babies down under...WOW...
