Tamiya mini cooper
Looked on 3racing website, their diff looks alot like this.
Only they use 2.4mm ball and probably a crap thrustwasher like on the M03 diff.
Tested the M03 diff from them and it was the best diff i have ever used for 2 batterypacks, that's how long the thrustbearing lasted. Got a new thrustbearing sent from 3racing, refitted it and tested again. Same story, 2 batterypacks and the car sounded like it had vario-matic transmission. Then i tested with a thrustbearing from TA05MS, and it was no more problem with thrustbearing. Now the diff carrier melted.
So, my advise is not to get any gear parts from 3racing.
But in my eager to get a non TA03 diff to test i have gone and ordered the 3racing one.

Will post back as soon as i know how it's like.... My guess is it's as bad as the M03 one.

Thanks for the replies. I have a Tekin FX-R but I wanted to try something different in the under 100 range. Also what's the best torque range for servo's? Which brand? Sorry for all the questions but I like to know what other people are using.

Sorry to raise a newbie question, I've been out of R/C for many years and trying to get back into R/C by getting into mini racing. I'm just about sorted on my car (M-03R) but a little confused on what wheels/tyres to get. I've been searching around for a while but couldn't find any clear answers.
I'm planning on running at my local track which is an indoor road track (Windsor, NSW, Australia).
Any advice would be appreciated (especially from anyone on this thread who runs there).
Thanks in advance.

I run Ride tyres on the front (soft 3020, medium, 3030 depends on grip level) with hard inserts, I run Pit Shimizu treaded D25 or Ride 3020 with soft 5mm insert on the rear. I have run Spice & Cross as well, but find the Ride tyres to be consistent (they are belted and wear well) Another great tyre is the treaded HPI X-Pattern run all round. A little hard to find stock though.
As far as rims go, I prefer the HPI Mini Dish Wheels (#3640) they are as tough as nails and don't break/chip/shatter edges when you try and rearrange the track walls. Others prefer the Swift rims, they are tough as well.
Look on RcTech for the following local threads,
M03/M05's - Aussie Mini Racing Thread
Windsor Indoor Hobby Centre
The Windsor regulars hang out at all these threads...
Look forward to seeing you at Windsor soon.
Cheers,

I don't know about the durability of the 3Racing gears, but here's what I do know. They're designed for more top speed, so racing on a relatively short track would probably not be advantageous. What I heard last week regarding teching is that if someone is running a bigger pinion than allowed, then they're probably using those gears.

Jim,
With the 3Racing speed gear set, you only need to change the spur gear. The secondary gear they have is the same as the Tamiya item. The problem is that a 20 tooth pinion can be fitted to the motor, but placed in the 16 pinion hole on the chassis. The gears are a different white colour to the Tamiya item. So Teching should be easy.
Personally for us here in Aust, I think you will know if someone is using them, as they will be faster than normal, especially with using the Hobbywing systems.
Yes I have a set, not fitted to my car, but will build a car for the TITC in Bangkok next year, which has open gearing, using Tamiya sport tuned motors. My major worry is that the motor will not last due to the heat from gears and the ambient temperature in Bangkok. These will be hand out motors.
Have a great day.
