Tamiya mini cooper
Hey Antlockyer,
This may be obvious, but did you use the Tamiya pinion guide when you installed your pinion on your motor?

Do you do this to all the gears very curious how much you chamfer the edges. Any chance you have a pic Thanks
When I built the kit I used it.
First race I had issues that sounded like loose pinion.
Guy and the track took the motor out for me and reinstalled the pinion using the guide.
Still didn't work, made weird sounds and had no drive.
If turned out that even using the guide it wasn't mating up properly.
I installed the pinion on the shaft with the gearbox apart so I could get it to exactly where it needed to be.
I'd done this a little wonky (it is right on the end of the shaft) so moved it down a mm and straightened it up.
Adjusting the camber should help w/ keeping your car straight and less twitchy. when i first setup my car I began w/ 3 degree negative in rear and 2 degree pos in front. Then worked towards neutral camber until car started to handle poorly ...for me the ideal camber turned out to be:
1.5 negative rear and about .5 pos front running long wheelbase.
What wheelbase are you running? I found that short wheelbase was much twitchier than long wheelbase. (never tried medium).
1.5 negative rear and about .5 pos front running long wheelbase.

As I have no adjusters I guess ride height is the only way I can adjust camber.
I make my own camber rods as I am not bound by any track rules or regulations.

and I can't find a picture of my M05 where I made the rear adjusters.. lol

I'll have a look at the car later and see what I have in my box of bits.

All you need to make adjustable camber links is 5mm short balls, some short adjusters and some 8mm set screws. Consider adding shims between the ball cups so if you get bumped or hit a board, they are less likely to jump a thread. I found that 0.5mm shim will change the camber by roughly 0.5 degree if you are around 2 degrees of negative camber.
The other thing to adjust to remove twitchyness is the toe-in front and rear.
For the rear toe-in I don't remember what the default plastic hubs are set at, but try playing w/ after market hubs if you can.
Yeah, the medium wheelbase should feel a bit more stable. I ran the short wheelbase for an entire season, switched to long and was like dang ...what a difference!

As for cutting the gears, ...what I did and found to work really well was to use some 1000 grit sand paper and lightly sand off the hard edges. I did this to all the plastic gearing. Just do it a little, to take off the hard edge on each tooth. After, clean w/ soap and water, let dry then lightly coat w/ a very fine spray of silicone. -use very sparingly.
Others may have other suggestions..

Let the rotor "tuning" begin... That is all.

M grips all around
Yellow front springs
Blue rear springs
Thin rear swaybar
Mount battery in rear position.
I found s grips to give slightly better traction, at the cost of replacing them much sooner.
