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.
--------------------------------------------------------------------------------------------------

NEW RULES EFFECTIVE SEPTEMBER 1, 2010.
Rules updated 08.27.2013. ESC Rule Changed on 6/2014.. All rules subject to change and expansion should need arise.
Note: As of June 6, 2014 the full list of ROAR 'blinky' ESC's are allowed in USVTA racing. See 'Approved ESCs' section below.

It is highly suggested that all indoor carpet tracks use these rules exactly as they are written with no deviations. Please try to keep it consistent and fair for everyone who may attend your track from around the country.

Trans Am Class Rules and Specifications
--------------------------------------------------------------------------------------------------------------


Body Specifications:
Late '60s to early '70s American pony car Vintage Trans-Am bodies only.
Note: Any 2-seat sports car (like the '67 Corvette Stingray) or any non-American built car (like the DeTomaso Pantera) does not fall under the American pony car category.

There are 22 officially approved USVTA bodies to pick from:



RJ Speed (aka. Bolink) part numbers:
1. #1054 - 1968 Chevrolet Camaro
2. #1055 - 1965 Ford Mustang


HPI part numbers:
3. #17510 - 1970 Plymouth AAR 'Cuda
4. #7494 - 1968 Chevrolet Camaro
5. #17531 - 1969 CHEVROLET CAMARO Z28
6. #17508 - 1965 Ford Shelby GT-350
7. #17519 - 1966 Ford Mustang GT
8. #104926 - 1966 FORD MUSTANG GT COUPE BODY
9. #17546 - 1970 Ford Mustang Boss 302 (scale wing ok- NOTE THIS IS NOT A SEDAN WING, IT IS THE SMALL SCALE WING)
10. #105106 - 1970 DODGE CHALLENGER BODY


McAllister Racing part numbers:
11. #286- 1969 Ford Mustang body
12. #295- 1970 Pontiac Firebird Trans Am body- 1/10- 200mm
13. #304- 1970 Chevrolet Camaro SS body- 1/10- 200mm
14. #305- 1968 Mercury Cougar body- 1/10- 200mm

For the HPI and Bolink/RJ Speed Mustangs and McAllister Cougar which are not provided with a spoiler:
A lexan spoiler of 16mm total height from trunk deck, and overall chord of 20mm is allowable. All other bodies must use the spoiler included with that specific body set as intended. Built in spoilers may not be enhanced.


Parma part numbers:
15. #10143 - 1969 Z28 Camaro
16. #10141 - 1970 Boss Mustang
17. #10113 - 1970 'Cuda

Protoform part numbers:

22. #1535-30 - 1971 Pontiac Firebird Trans Am


Wings or Spoilers: Body provided deck lid spoilers allowed (not wings). No additional skirts or raised/extended wings or air control surfaces allowed. Body must be trimmed at body trim lines. Front spoiler may be extended into body to provide durability. Full rear bumper required. It is highly preferred that bodies are detailed in race type livery in period-correct paint schemes. Fluorescent colors, wild graphics, chromes and non-period correct paint schemes are frowned upon. All cars must have a number on the hood, both doors and trunk lid. Wheel covers of any type are NOT allowed.

Driver Figures: All cars must include a driver figure consisting of at least a head and shoulders. Here are some examples of driver figure part numbers (ANY suitable 1/10 driver figure is legal - these are readily available examples)

HPI
#104815 INNER BODY SET FOR DT-1 TRUCK BODY

Associated
6180 Driver, unpainted, 1:10

McAllister
#423 Stock Interior and Driver
#419 SPRINT CAR DRIVER

Tire & Wheel Specifications:
The only tires allowed are HPI tire part #4793 "front" and #4797 "rear", using stock tire inserts provided with tire and any HPI Vintage wheels designed to fit these tires. All other tires and/or part numbers are illegal. Wheels and tires designated as "front" must be used as front tires/wheels, "rear" wheels/tires must used as rears. Five or Eight spoke wheels available in various colors. 0mm offset front wheels and 6mm offset rear wheels are intended for 26mm width fronts and 31mm width rear tires. 8-spoke Vintage wheels from #3805 through #3814, 5-spoke Vintage wheels from #3815 through #3822 and Vintage stock car wheels from #3854 through #3860, Vintage Wheel CC Type #33472 and #33473, Vintage Wheel DTP Type #33474 and #33475 are all legal wheels.

Grinding of tire tread is NOT permitted. Sanding of mold seam to remove seam is allowed. HPI Vintage Slicks and HPI Vintage Performance Tires are not allowed. Tire traction compounds are at the discretion of the track. No other altering, changing or softening of the tire is allowed. Tires may not be belted or changed to prevent "ballooning". All decisions of the race promoter or track owner are final. No "double stuffing" of foam inserts allowed—only single stock vintage tire inserts are allowed.

Chassis Specification:
Four Wheel Drive touring car chassis only. Any era or brand 4wd chassis is allowed.

Gear Ratios: Note: There is no gear ratio limitation in VTA. As a recommendation, a 4.0 FDR is a good place to start. An Excel spreadsheet gear ratio and final drive ratio calculator for most touring car chassis is available here.

Motor Specifications:
25.5 brushless with 2C LiPo: Novak SS25.5 Pro brushless motor (pn:3425V) Ballistic 25.5 (pn:3625V- stator only pn:S6625) Club (pn:3331) or Boss (pn:3626V) ONLY combined with any hard-cased 2C 7.4v LiPo pack up to and including 5000 mAh capacity. Novak motors are the ONLY motor allowed at this time. All house track rules regarding LiPo usage apply. Only physical motor timing advance is allowed, however Ballistic motors must not 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, end-bell, 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. Fans and external clip on heat-sinks are allowed, but integral type heatsinks/fans including but not limited to those that require motor disassembling to mount are illegal.

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

6/2014: THIS CLASS WILL NOW ALLOW ROAR SPEC CLASS ("BLINKY") APPROVED ESCS. CLICK HERE FOR CURRENT ROAR LIST.

HOBBYWING
..14. Hobbywing Juststock Club ESC (same esc, but differing part numbers):
. . a. Falcon Sekido Part #81020001 (Black)
. . b. Falcon Sekido Part #81020000 (Blue)
. . c. CRC Part # 7014 - Hobbywing XERUN Juststock Club No timing ESC - Sensored

Battery Specifications:
Battery must be a 2-cell (7.4V) LiPo hard cased, 5000 mAh limit.

Ride Height Specification:
Minimum ride height is 5mm.

Weight Specification:
Minimum 1550g in race-ready trim.

Race Specification:
- 5 minute qualifiers.
- 8 minute mains.
- Absolutely NO IFMAR-type starts. All heats and mains should be straight-up starts, with random sorts for each heat. 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.

Six

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.



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 )

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 Remember guys PRACTICE, PRACTICE, PRACTICE!

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?

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.

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.

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.

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
