Or, you can hang on to your 21.5 knowing that it's only a matter of time before 21.5 is the new standard for stock classes

Also about adding weight to slow them down;
The current Chicagoland Asphalt Assault VTA winner, who is also last years Hurrican series VTA winner, and the winner of the 2010 VTA nationals was using a TC5 that is 8 grams over the NEW WEIGHT regulation. So I am not buying into the more weight = slower car concept. We found that the car handled BETTER with the additional weight.

The neat thing, though, is that the cars are more driveable...THAT'S why they turn faster laps.

I think we are all finding out, that there realy is no true differance from 21.5 to 25.5, it just seems there is more low end que out of the 21.5, but we seem to run equal top speeds!
I ran with a fellow racer lastnight who decided to put the 25.5 in and it seemed pretty fair, we ran identical batteries and both abided by the gearing spek!

And what gearing spec would that be for the 25.5?
And the same top end but more bottom end means an advantage to the motor with more bottom end...stringing together the infield turns. What you're identifying is the bugaboo that sank the "equivalency" between brushed 4-cell original spec VTA and the 2s 21.5 spec. Gearing limitation on the later kept top speed the same, but the tighter the infield the more advantage the newer spec had due to significantly more "poke" off the turns.
Equivalency formulas rarely (if ever} work as equally as their creators hope (or try to believe).

We updated our gearing chart and added the 25.5 T motor:

I don't know if our upcoming NovaGear App will be helpful for your racing, or not.

Tekin RS ESC
What's the recommended set-up for a Tekin ESC? 21.5 and 25.5

A Novak, LRP, or Speed Passions ESC that is on the list (sorry couldn't resist 
). Only the specific speed controls listed in the rules are allowed (at the National level). If you are running local club races and they are allowing the Tekin at your track, use the zero timing and zero Advanced Profile signified by blinking red LED when in neutral (not sure what the current software revision number is).

If for some reason it's legal where you are to run one, you need to have V208 firmware installed, and then select Timing Profile 1. You do not need the Hotwire PC interface to do so -- just follow the instructions for how to engage TP1.
When TP1 is selected, the center LED on the ESC will flash constantly (except for a brief appearance from the temp LED every 5 seconds) to make it easy to tech.
In this mode, the Tekin uses absolutely zero timing advance, boost, turbo, etc. and is exactly equivalent to any of the approved ESCs.

We appreciate the support of the USVTA drivers and hobby dealers!
Any questions about gearing and FDR should be emailed to [email protected]---they are Novak's car experts.

I really appreciate your participation in our discussions and willingness to share information that keeps us on track. I think it probably sells more Novak product than most advertising campaigns. Since you probably know more about the 21.5 and 25.5 motors than anyone, would you care to comment on our attempts to run these together via FDR limits. Our track has adopted 4.9 for 21.5 and 4.0 for 25.5. The math works out for similar top speeds but this does not take torque curves into account. Our first race of the season is a week from today so it isn't too late to revisit these numbers if you think we can tweak them a little to make them better.
