According to the late Big Jim Greenemeyer, Lap times are the one and only, best way to get the proper gearing. I beleive that is true. Each track layout can require a different ratio (same motor) to get the best feel.

That being said, I usually show up just in time to race and use nearly the same gearing all the time. I have started a spreadsheet to keep track of amp draw while running in motors, the gearing used, and a note about performance.

One day I will have a set formula. One day I will have experience as well. Or maybe not...

Personally on the comm drops. I'm not a big fan. Clean is good.

Speed control and radio set up will play a major part in stock racing as well.

Oh by the way, to place silver on a com cost twice as what a new motor would cost you.

But if it runs like a 19T the cost is worth it,imop.remember,speed cost $$$ how fast do you want to go.I would be interested in learning this process.

I know almost everyone uses either F-Brushes or Hurricane Gold Brushes. But what about Reedy 767s and Trinity 4499s also what about the Trinity 4070? Also what about the Reedy 767s with the hole drilled through?

Most people I presume either use red/green, red/red or purple/purple spring combinations.

Got some reccomendations a couple pages back just looking for some more.

Also what about shimming the motor, reaming or polishing the bushings etc...?

Thanks,

Crash,

All the things you mentioned are pretty much standard items for blueprinting a motor,no one is going to tell you the REAL speed secrets,that's one reason that brushless racing is getting so big,it takes motors out of the equation.

I usually cut mine when I notice the performance falling off. Usually around 10 runs or so.

Usually you can monitor your motors performance with a amp draw check and you can tell when it needs to be rebuilt.I use my MM motor master just for this.

the money motor is a 19t, but silver springs with infinity brushes are the ticket for tc racing.

Checkpoint makes them, anywhere that sells checkpoint motors, stormer comes to mind, yes they are silver.

As for the dyno, I am not sure, I got mine "tuned" from a popular shop here, but it had no dyno sheet like they claimed, and it did not come with the better brushes/springs either, but I won't be r00d and name them
