I'm not sure adding another motor to the mix is very produtive at this time. The rules as they are now, provide for the racer to use a power combo he may already own or step up and spring for the 21.5 option. It's really easy for me to understand. Some day in the near future, we will not have any choice when it comes to using lipo's. The 4 cell/6cell pack as we know it will no longer be availible. Same for brushed/brushless motors. The way I see it, current rules allow most anyone to race in this class. I know you die hard racers can have fun at this too. Race hard but slow down to enjoy life. Big Jim
MERRY CHRISTMAS TOO ALL!!!!

Does a 23.5 even exist? It shouldnt be to hard to come up with if you had some mfr support. Just build a Novak 21.5 and go around two more times.
If the motor really existed and was readily available, I would actually think it was a good idea. However the class has a lot of momentum as it is and 21.5 lipo will likely be the standard if the rules are just left the way they are.

I believe this to be the "spirit" of the class as I interpret it.
The chassis is a 415 MSX that my son campaigned before the 416
Battery is an Orion 3400 Lipo from this years TCS NA finals
21.5 Novak Brushless with a GTB
Valvoline scheme is what I think it would look like if Valvoline raced in this series in the early 70's
As soon as I get sticker sheets from Wallstreet it will be finished
You don't have to be Vintage to know Vintage................but it helps

I agree. I have just completed this for the TA class at the Novak Race.

apples to apples
Rushing to create equivalents as we given new technology has always been a problem. I experienced this when brushless was new to the hobby...the club I raced at had 13.5 running in 1/12 stock..unless you had the "new stuff" you were just trying to keep out of the way. Later on ROAR announced 17.5 as the equivalent...that worked better and everyone in the class now has a reasonable chance to "compete".
The 21.5 Lipo spec is just a repeat of trying to fit "new stuff" into a class.
I would expect that ROAR has more resources and done more testing than anyone. I'm satisfied with ROAR's eqivalence spec of 17.5 and 27T..both using 4 cells. The fact that ROAR does not endorse 21.5 Lipo/2S as an equivalent to 27T and 17.5 4 cell should be reason enough to not paint outside the lines. When a 4 cell replacement comes available, I'll run 'em...untill then I can wait.
-To be clear... I'm not "anti-lipo" I'm for class parity.
Yes, I race TA...It's easily my favorite class. I don't need blinding speed to have a fun race and I don't mind working on my car. (I'm running 4 cell 17.5) I just want to put a race car down that's "apples to apples" with my competition. Maybe you guys just need a category 2 class to appease the Lipo folks...It'd be cool to run a Vintage Vette or Porsche!

That is not entirly acurate.
ROAR's provisional rule package for VTA is identical to USVTA with exception to specing the size of the tire instead of stating its manufacturer.
They do not state they are equal just allowed to run in the class.

roar specs
I stand corrected ...I guess.
Honestly it's a bit of a letdown knowing that ROAR would have unequal cars competing. Isn't it much of their purpose to write rules and test equipment to keep racing competitive? Seems to go directly against that line of thinking.
Add: I can't agree with the FDR method of equating equivalents. Anyone with some exposure to science can see the flaws in such a method. A weight(grams) to power(Watts) ratio is the proper approach. I can see all the problems that would create too, run time, setup, room for ballast on a crowded chassis.

Not sure how everyone else has been mounting their tires, but I take a few extra minutes to remove the plating on the wheel where I'm going to glue. I've found that the tires stay glued to the wheel much better by getting down to the plastic. I've noticed otherwise that the plating gets glued to the tire and pulls off from the wheel. I normally use the 5-spoke matte finish wheels and they seem to hold up really well.
I'd be interested to hear how the other plastic (non-plated) vintage wheels hold up to racing.
