Thank you for posting the latest rules update.

I think another question is, who is writing these rules? This is not ROAR. Is it a committee?

USVTA Vintage R/C Racing


Welcome to the home for the newly created Vintage T/A 1/10th scale R/C road racing class, based on 4wd touring cars. The class rules are developed to provide close racing with controlled chassis, battery, motor, tire and body specifications. The goal of the VTA class is to bring back awesome looking cars in a cost controlled racing format where the result is just plain fun. The speed of the specification package brings close and competitive racing for sportsman, intermediate and experienced hobbyist that rewards driver development.

With a decline in all R/C racing in recent years, racing needs a big shot of fun and excitement--and this is the perfect class. Far more reasonable speeds, low costs, realistic and exciting looking bodies, wheels and tires, less traction and wheel-to-wheel action drive this class. It IS the next big thing. It's appealing not only to spectators, but to new and old racers, alike. For a low initial cost, any prospective Trans-Am racer can get a car, a radio and be racing with very little time or effort. And the fact is that racers who have never raced before can be on the same level playing field as everyone else, and really enjoy doing so.

The basic rules were created by energetic and insightful racers in Wisconsin and Illinois, and have proven to be very effective and successful. All rules will evolve and adapt as the class warrants. New participating tracks are encouraged to grow the class and adapt ideas to the class, and share those ideas with the U.S. Vintage Trans-Am Series, yet stay true to the original ideas and rules. Hopefully, we can all make this a great class to grow with, and bring back the fun and entertainment to road racing.

If your track would like to be a general participating track and run the USVTA class and rules, please [email protected] with any questions you may have. We'd love to have you on board.

Thanks for the insight.

1st problem is that hotmail was phased out in 2013. I was going to ask if this group was still active, but since we just saw an update.

At my local track, VTA has become one of the more dominant classes. For the most part Participation is great. We all struggle with the nuances of this class, but body weight seems odd to change. I wonder what the motivation behind the change is.

Simple, to stop the guys that throw one coat of paint half way on the body for high traction tracks and run it like that

Body weight is something that has come into play for other classes in recent years. From what I heard, the development of ultra lite and pro lite bodies has been partially blamed for increasing occurrence of body tuck. The super thin bodies also don't last near as long for those of us that are less than perfect drivers. Some people also would only dust the body with paint to keep it as light as possible, and it doesn't generally make for a great paint job. I haven't run VTA in a year or two, but my cars have been so light that I have to add so much weight that I run out of places to put it all, and that's for standard 1350 TC minimum!

Again, trying to understand do please do not take this as an attack on you. How is this a problem? What does it really affect? Is the fact that some uses a light coat of paint helping them win? I have done that a few times not because I think it will give me an advantage, but I only had enough paint to give a light coat.

I am more concerned, and frustrated that a rule was instigated that has no real meaning, but is forcing me to change my cars and spend more money. No new bodies have been added to the list in over a year, but now we are going to limit the existing ones? The point of a rule like this should be to take away or an unfair advantage one has over another. We already have a weight limit. It should be up to the driver how they achieve that weight. If I choose and or feel the car responds better, to spend more time putting all my weight at the center of the chassis, then I should be rewarded for doing so.

If the goal is to level the playing field a roll out or gear limit would be much more effective. If this is going to be a real class, it needs to be treated as such. Rules need to rolled out at the beginning of the year and those rules need to hold through the year. If a rule needs to change an announcement should be made and an explanation to the rule should be announced.

That still does not make it right

I hear this sort of thing a lot when it comes to disagreements with VTA rules. I suppose if you race at a small track in the middle of nowhere, and plan to stay there, you can do as you please, when you please, about rules. Those of us that race at tracks that host bigger "sanctioned" races or those of us that attend out of town "sanctioned" races are affected immediately, and it seems, are given zero warning or say in the matter.
