Scottrick,
Are those spacers going to work out for the Niftech crowd? Ironically, that discovery is going to be the springboard for the 10th scale diff thrust bearing. It looks like they are going to bolt right on so that 10th scale guys will enjoy the same benafits as us little dudes.

That's right.... 10th scale thrust bearings! Go back to work on your car, not your diff.

Hmmm... I might keep that slogan.

I still like: because you need and don't know it.

Default Roll out

Roll out is a great way to find out what gear ratio is needed in 12th scale. Your buddy might run a 1.75 roll out on his "what ever" motor. You have the same thing but you are either slower or dumping but your pinion and spur are identical. What's missing? Tire size.

For every one rev of the motor, the car will go X forward. That is roll out. Whether you choose metric or inches, you need make sure you are using the same scale with your buddy. Most seem to use inches in the states.

Tire dia times pi(3.14) divided by spur times pinion equals roll out.

Roughly for every .080in of tire worn away will equal one tooth needing to be added on a 64 tooth pinion to maintain the same roll out. Roll out charts are real handy for comparing ratios with your buddies or with various motors. You might learn that brand X brush likes this roll out while brand Y brush likes that roll when the motor is the same.

So when you go to your local track to find out the Komodos run a 1.78 roll out with a 767 with trialing edges cut and red/red springs... you can look on your chart to find the tire size and pinion/spur ratio needed to get the job done!

Handy as a pocket on a shirt!

Brian,

Just popped a Niftech axle together--looks like they'll work a treat.

Thanks again,

Just couple question about the 12L4, indoor carpet and stock motor

(1) Running stock (monster or Co27) w/96 spur....what is a good ball park rollout?
(2) Tires diameter F or R...? (that will be reference to the above roll out..)
(3) Tires...I know it is very much standard front PURPLE rear GREY...but I am wonder, is PARMA front purple = Jaco front purple? Vise Versa...Parma rear grey = Jaco rear grey...? or what shores should I use for JACO.. (I already know about PARMA)

Thanks in advance.....
