Thank you IBLib.

The first thing that anybody should know about U.S. Vintage Trans Am is where to find the rules.
Click here to see the official U.S. VTA Rules web page. It should look similar to what you see below.

Chassis Specification:
Four Wheel Drive touring car chassis only. Any era or brand 4wd chassis is allowed.
***All Cars must be Full Time 4wheel drive no “1-way” diff or pulley system is allowed***

Motor Specifications:

pn:S6625) Club (pn:3331) or Boss (pn:3626V) are grandfathered in and also legal
All house track rules regarding LiPo usage apply. Only physical motor timing advance is
allowed, however Ballistic/Boss motors may be advanced beyond the last line of the timing
range sticker. 12.3 mm rotor diameter only (no "tuning" rotors are allowed, only stock Novak rotors allowed). Using ceramic bearings in the motor makes you a dork. No modifications or optional parts allowed on motor can, endbell, stator, or rotor other than the Boss #5925 Ballistic 540 Vented Endbell/Bearing Racing Upgrade Kit (replacement) . No cooling holes or other changes allowed to motor.

Ride Height Specification:
Minimum ride height is 5mm on Carpet.

Weight Specification:
Minimum 1450g in race-ready trim.

Race Specification:
- 5 minute qualifiers.
- 8 minute mains.
- Larger Races IFMAR-type starts are a better option. All smaller “club” heats and mains
should be straight-up starts, with random sorts for each heat if desired. Non random sorts
should shuffle starting order for each heat.

Optional Main Variations:
- 12-20 car A-mains, depending on car counts.
- Invert qualifying order based on random hat pull (top 6-10 cars).
- "LeMans" type starts where all cars are lined up on an angle to the racing line in order.
- Run track in reverse rotation for mains.
- Rolling starts.

MOST IMPORTANTLY: If it's not in the rules, and does not encompass the spirit of slower, controlled racing with realistic looking cars, consider it illegal. This is called the "Spirit of VTA" Rule.

The class is based on slower, equal playing field competition with less traction, minimal aerodynamic aids and mostly older carpet racing technology. The final objective is close, fair, wheel-to-wheel racing for all.

All decisions of the race promoter or track owner are final.

Is anyone else having to drill mount holes into 12th scale spur gears in order to make the ratio and fit in the motor mount? I dont mind doing it and it seems to work ok, but am I the only one?

Also since we are starting a new thread I have to link back to the Battlefield Road Course page. http://www.battlefieldraceway.com/RoadCourse.htm

There you will find some great videos and some pics of my USGT ride and My USGTA ride.

Yep, there's my baby.

http://i1214.photobucket.com/albums/...s/IMG_0712.jpg

Sharpie,

I don't think I gave you my car information so here it is.

1. Bill Belsher, Fort Worth, TX.
2. How did you hear about VTA racing at the ROAR Carpet Nats? When Andrew sent out the first official post about the classes for the NATS.
3. What kind of the following products did you use in VTA at the Nats?
a. Chassis: XRAY (can't exactly say what year, it is a T2R Pro fiberglass chassis bottom plate and T2 R Pro/008 aluminum bulkheads, a T2 009 EU spec graphite top plate, T2R Pro front shock tower, T2 009 Rear shock tower, T2 007 front axles, T2 007 Steel steering and camber links, T3 38 tooth belts and pulleys with a Spec R rear gear diff, and T3 2012 shocks)
b. ESC: Novak Edge
c. Motor: Novak Ballistic 25.5
d. Servo: Savox 1251MG
e. Battery: Primary Venom 2S 5000 mah 60C (USVTA Legal) and a SpeedZone Pearless Series 5600 70C 2S (one of my Dirt Oval midified batteries as a backup because I have already had to warranty this Venom for a broken positive battery tube once)
f. Radio: Futaba 3PM MX (yeah it's F.A.A.S.T. unfortunately I wasn't last weekend :weird::cry::eek::rolleyes::ha::ha::ha::tire::nod: )

Oh and one you forgot Sharpie

G Body: McAllister #286 1969 Mustang VTA

I have to admit, this body held up VERY well this weekend. Usually the front of my body is destroyed after a couple of heats but this body held up for the whole weekend with only minor cracking. The best part is I also used a XRAY hard front bumper and it fit intact under the body (no whittling on the bumper to make the body fit right).

YES THIS CAR IS FULLY USVTA LEGAL, unfortunately I did not get a handle on my electrical and handling problems in time to get any meaningful practice with this car. I finally got it to come around during the 1st heat Friday and still haven't found the sweet spot on this new motor. Maybe next year :nod::tire::spidey: Remember guys PRACTICE, PRACTICE, PRACTICE! :D

So there's a Mcallister VTA in the flesh... looks good. I just grabbed a bunch of shells from them for my local club to run in a spec class, very happy with how solid the lexan is. Good stuff.

Classic question:

"Is there an FDR rule?"

NO!!!!!!

4.0 is a good place to start, HOWEVER, adjust your FDR based on track size, driving style and motor temps!

Now, who wants to start the first argument/debate that's been addressed 20 times already in the old thread?;)

:D:D:D

We could always go back to the body that should be legal because its cool even though it never was a trans am racer but I really really like it argument.:ha::ha::lol:

SWTour 03-21-2012 07:21 PM

Is there a good setup for an old TC3 - Asphalt/Parking Lot type surface, pretty smooth, medium traction VTA Setup (or even a USGT type setup)

Springs / Oils / Chassis Height/rake / Droop, etc.

Ed Anderson 03-21-2012 07:29 PM

Looks like this thread is already messed up too. You have to scroll back and forth.. back and forth... just to read it... :rolleyes: I gave up trying to read the last couple pages of the other thread

I personally stick to the J71, even if the other guys at the track think it's ugly. But really it doesn't matter, as long as the car is set up well ;).

I like the j71 except for the nose. I hit too many things for a two piece nose. :lol:

I agree. Set up is everything. I have run a lot of different bodies and they don't make any difference in the way the car performs. at least not in vta
