Hey Granpa,

For what it's worth, I run 64 pitch (corrected from 48p) pinions with Tamiya spurs on my F1's all the time without consequence.
I heard that it's wrong but all I notice is a little noise, kinda the same as a nicked spur.

I'm amazed you can run a 48dp pinion with a 0.6mod spur. They are VERY different. 0.6mod comes out roughly the same as 42dp.

0.8mod (which is what some of the basic Tamiya buggies still run) is about the same as 32dp.

0.4mod (which is what some of the higher-end on-road cars are supplied with) is about the same as 64dp. They can mesh, but not cleanly.

gtfour93, the 20 pinion in the link you provided is for a 48 pitch pinion. Unless I'm really wrong, these don't work in a Mini. The Mini uses a metric pinion which I was able to find at Tower, so Thanks for trying.

The Robinson pinion is well made and has the advantage of a stronger set screw hole and is less than half the cost. The Tamiya Flourine coated pinion lasts but eventually the set screw threads give up.

I am not 100% sure about the 48 pitch and metric info, but I'm sure there are a number of Mini gurus who can set us straight
Grandpa sounds like you found the correct pinion.

The M03/M05 uses .6 module pinions. This is the same as Robinson Racing's Metric 48 pitch pinions found here (20T) http://www3.towerhobbies.com/cgi-bin...?&I=LXEX43&P=7
But the setscrew uses is a standard allen wrench and not a metric one.

Correct. And it's a larger 5-40 size, so it lasts much longer than the smaller standard 4-40 set screw. Me likey!

My bad, I should have said 64 pitch is what I run.
The 48 pitch is on my offroad stuff.
Sorry and thanks.

I'm gonna fix my post above.

What is the difference between the Tamiya "M" and "S" tire compounds?

wow, I remember coming to this thread several years ago. It's still going, haha. I guess the admin don't really do much maintainence.

M - medium/hard compound, it's usually the stock tires that you get from the kit.
S - soft compound (s-grip), it's a tamiya hop-up item.

I don't recall any 64 pitch gears for M chassis. Only saw them on formula one cars. When dealing with 64 pitch, there is no metric vs american. However on 48 pitch, there is metric and american. If M chassis can use 64 pitch gears in the future, that will be very cool and more efficient. M chassis is known for noisy gearbox.

there is 3 types of mini tyre from Tamiya

kit tyres (hardest)
M grip (medium and shortest life)
S grip (soft but last longer than the M grips :S)

this is my limited experience though

M - is a different compound then the kit tires...the M-Grip and kit tires are 2 completely different part numbers, so they aren't the same

Why would the admin have to do any maintenance when we communicate and share helpful and useful info about the mini.

Where do the type "A" slicks fall into the compound range? And, now they are a "B" compound.

type A is softer than type B.

I recall type A works good on Carpet, it had some temperature rating listed on the back of the tire box.

Type B is a good choice for running outside on asphalt, it can handle higher temp and rougher surface.

Tamiya made type A belted slicks before, those are very sticky and easy to traction roll the car.
