We've had solid novice fields all season so far, so I'd assume so!

My son will run in the novice class with a silvercan. He hasn't had any practice with the 17.5 so he was a little anxious about running in stock class.

If he's an experienced racer, but is just nervous about 17.5, take a look at the Scale Spec class. There's a wide range of skill level in that class. The silver can motor is very well-matched against the 25.5 brushless.

Congrats on your new car! Most TC6 racers use a AE/Kimbrough 96 tooth spur for stock racing. This is great for getting you in the low 4's down to mid 3's. Not sure where others are running there 25.5 but im guessing low 3's. So a 92 should be a better choice. I've used 92's to go mid 3's. If your going even lower maybe a 88 is the way... In fact after running the numbers a Kimbrough 88T 64P spur sounds right!

96T spur and 52T pinion puts you at a 3.7 FDR. This is about as low as you can go with a 96T spur.

92T - 52T pinion = 3.53 FDR

88T - 50T pinion = 3.52 FDR
88T - 51T = 3.45
88T - 52T = 3.38
88T - 53T = 3.32
88T - 54T = 3.26


Hope this helps you select your gears after a Scale Spec racers posts up what a good starting FDR should be.

Default FDR for scale spec

TQ Racing has a great gear chart that gives you the ratio of the pinion/spur that you request plus a chart the 5 gears up and down of both the pinion and the spur. It will print out to a nice chart to take to the track.
ww.tqrcracing.com/rc_tools/gearing.asp
You might start off around 3.6 FDR to start and see what temps you are running for Scale Spec. I think that I am at a 84p/53s with internal ratio of 2.25 for a final of 3.56. There are some guys running down at 3.3 or lower but watch the heat.

Rob is onto something that a good place to start is 3.6:1. Learning drivers might want to go with 3.7 or 3.8:1. Super-smooth drivers can go lower (3.5:1 or lower).

For me 3.8:1 worked the best for many months. Gradually as I began to keep my corner speed better, 3.7:1 worked ... then 3.6:1 ... , etc. Until finally I've arrived at 3.45:1, with a fan, running 48 pitch gears (69t spur, 40t pinion). The equivalent 64p gears are listed below.

Note that at FDR of 3.5:1 or lower, one should definitely watch motor temps and strongly consider running a motor fan.

spur pinion fdr
48 pitch 69 40 3.45
64 pitch 92 53 3.47

Please do holler with any questions. All of us are happy to help.

Default New Years Eve Race Jam

Okay, so it's not exactly New Years Eve, but it's the closest Saturday night to it, which in my day always meant a party! Of course, these days, absent a race, it means collapsing face first into the pillow, exhausted and despairing that there is still another 9 days of Christmas break, ignoring a front room that looks like the dumpster corral behind Santa's workshop, with a highlight reel of youthful exploits playing in the mind like a Mid-Life's Mockery Marathon on TBS. But I digress.

It is a Race Night! So, let's strap it up and take inspiration from the grandest of undefeated old men. Growl like Eastwood and say it with me: "Yeah, it's halftime Seattle. And our second half is about to begin."

We're setting up at 3pm, so anyone who isn't tearing it up at NORA please join us to roll out the rug and build our track with a fresh layout. If you are running at NORA, have a blast! I've talked to Allen and he plans to lock the doors behind him at 3pm so he can be down here at 4pm for the second half of the doubleheader. On my clock, that works out to roughly 18 hours of racing. CRAAZZY!

See you Saturday.

3pm Setup
4pm Practice
6pm Q1

It seems to me, that ESC's have an effect on gearing as well. I may be wrong, but I've had different speedo's give me different feels/temps with the same gearing before.

As Bill said, 3.6 is a great place to start. As you get smoother (scale spec is all about corner speed), you'll be able to drop the gearing down without overheating and still be able to have the speed/punch you desire. Come bug us at any time with questions!

Jared, to be clear, all that gearing talk was for 25.5. To go with that, start the motor timing at about 35*. If you're still running silver car, then you'll want to be up around a 5.7 FDR as a baseline.

So... The only difference between scale spec and novice is the tire requirement?

Default Totally Sweat!

Extra practice on the new layout!? Bravo! Well done!

Im thinking about closing the Tub for 30 minutes, between 5:15-5:45 on Satruday so I can cut tires and practice.

See everyone soon!
