Pretty much the same rules that roar uses for VTA. 1450g weight limit, any 25.5 motor, any roar approved blinky speedo. Any 2s battery maybe (not sure about the battery one).

We had a great VTA turn-out (18 cars) in Indy last Friday. We even had a C main!! Best weekly racing this year.
----------
In response to motor/speed control temps...
I have been running my VTA car with just a large heat sink (no fan) on my motor for the past year - indoors on carpet. Unless my setup was really bad or I overgeared my car, my motor stayed under 160 degrees. I've never temped my GTB speed control, but have never noticed it being warm to the touch.
If you are running outside during the summer on an asphalt track, it would be advisable to run a fan on the motor and/or speed control just to be safe. However in my experience you don't need a fan on your motor/speed control when running VTA inside. If your motor and/or speed control are getting excessively hot, it may be an indication that something isn't working well on your car.
Bottom line, you don't need cooling fans to win in VTA. However, anything to help keep your electronics cool will extend their life.

Here is a link on Tower Hobbies to the Associated TC3 #3928 heat sink I'm using (http://www3.towerhobbies.com/cgi-bin...?&I=LXTG84&P=7)

I use the fan that came with the Justock to cool the motor.

I'm curious if there is much of a difference, if any, in lap times for outlaw VTA? I'm converting my USGT to VTA and find it somewhat annoying to have to pull a new orion esc out of it when it wouldn't give me an advantage unless I wanted to cheat. I don't think anyone local would care, if its in blinky, so that's why I'm curious what your observations at Michiana Raceway are. I am still going to change it because I want the ability to travel with it. Thanks

VTA
Outlaw VTA at our track came about by not enforcing the USVTA rules and letting one thing go to another then all of a sudden you have cars weighing 1400_1460 grams all running 6500 mah 100 C lipos with multiple 25.5's.
It's tough to pull it back so esssentially 2 classes were started. USVTA by the rules and Outlaw.
outlaw is 1450 grams, any esc in blinky and at our track a novak 25.5 or phantom 25.5 with stock rotors. As for performance there is a difference with the advantage to the outlaw car. Some of which is contributed to the electronic's and some from being 100 grams lighter.
Since we split the classes USVTA has grown 3 times and outlaw has the orig 5-6 guys. Our season is almost over as the track runs winter only so were waiting to see what next year brings. A few of us have started running the USGT cars and we have that as a class at our "King Of The Road" trophy race March 9TH.
The guys who travel built USVTA cars from the beginning because we can race it anywhere and if someone comes to our track they know their racing equally prepped cars. I call Outlaw a bastard class, as in no one else runs it. From my understanding even roar races use 1550 grams the last 2 yrs. They haven't been 1450 since 2010.

In response to MarkerInbound
It has been shown in actual racing conditions using ROAR VTA rules that blinky speed controls don't have an advantage over the USVTA approved speed controls. The problem is that for club racing, there is no way to prevent the racers from cheating unless they tech each car each time they hit the track.
The problem with allowing ROAR approved blinky speed controls when everyone else is running USVTA approved speed controls, is that I will accuse you of cheating. I know you aren't getting an advantage unless you (to use your words) "wanted to cheat". I can't be certain you aren't cheating unless I tech your car before each heat/main.
To be fair and realistic, I would never ask anyone to buy a new speed control just to try out VTA. But you already have the answer to your question - Run your ROAR approved VTA car in USGT. A well setup VTA car can be surprisingly competitive on a small to medium sized carpet track (Michiana carpet track). At worst you might be 1-2 laps off TQ in USGT. At our track in Indy, the better USVTA drivers would normally qualify in the USGT A-main on a local club race night.

That makes sense. Thanks guys
Another Question: I am in the process of putting a 25.5T stator, part# S6625, in a second hand Novak Ballistic 10.5T motor. The rotor is a little damaged from a pinion screw by the previous owner but workable. What is the best way to tech the rotor for the required 1.3mm VTA limit and where is it measured from? Thanks

"In effect for this race. N.E."
What means this?

You are correct about ROAR. The last two national events that ran VTA were 1550 grams and 25.5 motors even though it seems they still haven't updated the rule book. The difference with ROAR is that any "approved" 25.5 motor is allowed with any "approved" speed control capable of non-timing "blinky" race mode. They also have no limit on battery capacity. So this class is truly unique to your track because it doesn't fit either ROAR or USVTA rules.
