On the subject of diffs, is the Tamiya 54194 the one to use and is anyone running the Tamiya 54238 reinforced ball differential cup ?

RossoToro was modding a Sakura sealed diff for use.

Firefox,

Yes you can use those parts with the MO5 diff, that way you do not have to use blades on the end of the universals.

I also use the 416 diff nut, redrilled and tapped to take a 2.5mm diff screw and change the thrust bearing, to a 6 x 3mm bearing or get a rebuildable thrust bearing.

I only change this so that I can make the diff tight, so that I do not have diffing out when using the 13T BL system we use here in Australia.

The 3Racing Sukara gear oil diff is the incorrect pitch and requires modifying to use properly, unless you just run it in. I have heard of others using modified NT1 gear oil diffs.

Perhaps after TITC 3Racing or Yeah might come out with something. Who knows SPECR have already built a FF03 oil diff, so just a rejigged outer could be on the cards for mini.

I do know that one can be modified very easily to use in a mini, however durability testing is still being conducted. Diff oil weight being tested is 500 000 for more front hook up. At this time he is not willing to share until race proven.

Hopefully one will be released in the future.

Good luck.

Calvin.

Calvin which part is this? Do you have a part number? I just acquired an M05 ball diff and I would like to change the wornout outdrive

This thread (well the last ~50 pages) has been really helpful for me!

And I'd like to post some pics of my Mini's but can't link to them... how many posts do you need? The message is rather unhelpful...

TIA

Martin,

Slow is fast. So they tell me. You would know all about that. I believe the record is in your favour, not mine.

Thanks for that fixed my post.

I have been testing with a MO5S and it seems to be very stable and precise. I am running a ABC Mugen body on the car with only the 1.5 degree rear hubs and the Tamiya motor heatsink as the only hopups. The car still has the plastic steering and plastic front knuckles. I have found some lead ballast in the front bumper works well.

I have some steering hopups ready to fit as soon as the plastic ones show signs of trouble. I have both the Tamiya and Yeah sets. I have used the Tamiya set but not the Yeah racing set, so might try it. I see it is supposed to make ackerman changes easier on race day. I just need to see how durable the set will be.

I also noticed that now we are spoilt for 60D size mini tyres. Pit Shimizu, Ride and Tamiya all make a variety of temperature rated tyres. These are good for an open track but might be a handful for a tight technical track. I suppose that will depend on car setup.

Calvin.

Thanks for the replies all.

So is the Tamiya 53267 TA03 ball diff a drop in for the M05 or are other parts needed ?

Yep direct drop in. Dont use two of the white gears though.

You use the gear which goes actually inside the diff and holds the diff balls but not the other two white gear parts.

And lastly, does anyone run the 3Racong M05 Solid Axle ?
I don't think Tamiya makes a solid axle for the M05.
