VTA RULES
Rules updated 9.7.08. All rules subject to change and expansion should need arise.
Complete downloadable and printable 2008 Rulebook is available in PDF format here. 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.
HPI part numbers:
17510 - 1970 Plymouth AAR 'Cuda
17519 - 1966 Ford Mustang GT
17508 - 1965 Ford Shelby GT-350
7494 - 1968 Chevrolet Camaro
Parma part numbers:
10143 - 1969 Z28 Camaro
10141 - 1970 Boss Mustang
10113 - 1970 'Cuda
Pegasus Hobbies part numbers:
PGH4001 - 1970 Camaro SS
PGH4002 - 1970 'Cuda
PGH4003 - 1970 Mustang
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. 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 trunklid. Wheel covers of any type are NOT allowed.
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. 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 are all legal wheels.
Grinding of tire tread is NOT permitted. Sanding of mold seam to remove seam is allowed. HPI Vintage Slicks are not allowed. Tire traction compounds are at the discretion of the track. No other altering, changing or softening of the tire is allowed. 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. An Excel spreadsheet gear ratio and final drive ratio calculator for most touring car chassis is available here.
Motor Specifications:
Option 1: 27-turn ROAR stock motor: No FDR limit, bearings are not allowed.
Option 2: 17.5 brushless: Motor timing advance is allowed. 12.5 mm rotor diameter maximum (no "tuning" rotors are allowed).
Option 3: 21.5 brushless with 2C LiPo: Novak SS21.5 Pro brushless motor (pn:3421) ONLY combined with any ROAR-approved hard-cased 2C 7.4v LiPo pack up to and including 5000 mAh capacity. Novak motor is the ONLY motor allowed at this time, because there are no ROAR mandates or restrictions for the 21.5 brushless motors. All house track rules regarding LiPo usage apply. Final drive ratio is to not exceed 4.2. Motor timing advance is allowed. 12.5 mm rotor diameter maximum (no "tuning" rotors are allowed).
Suggested gearing FDR recommendations:
27t brushed/4-cell: 5.4 - 5.7 FDR
17.5 brushless/4-cell: 3.5 - 3.7 FDR
21.5 brushless/LiPo: 4.2 - 4.6 FDR
Tracks should not dictate which motor combination a racer should choose. All three motor/battery combos have been tested to compete evenly against one another in competition with great success. If any one power choice shows a definitive advantage at a certain track, it is up to the race management to even the racing out via suggested gearing changes.
Battery Specifications:
4 cell NiCd or NiMh batteries, 4600 mAh limit
2 cell ROAR-approved LiPo hard cased, 5000 mAh limit (21.5 brushless motor option ONLY)
Ride Height Specification:
Minimum ride height is 5mm.
Weight Specification:
Minimum 1450g 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.
MINI COOPER RULES
Mini Chassis Classic Top
The Mini's are for everyone wanting to race close and have fun doing it! This class is ideal for any racing hobbyist wanting to keep racing simple and fun. It is very competitive, but without the pressure! Fun is the game here with stock silver can motor power.
1. Any Tamiya M03 or M04 chassis car that uses the 60D size tire or smaller.
2.Tamiya Hop-Ups only.
3. No chassis lightening allowed.
4. A proper mini body must be used with its proper mini chassis. I.E. (A front wheel drive body must be used with a front-drive chassis. A rear wheel drive body must be used with a rear wheel chassis)
5.Tamiya 60D tires and wheels only (50683, 50684, 53254 and 53340).
6.New for 2009: Stuffing tires with inserts to create a "ballooned" tire, and producing overdrive is not legal. Tire diameter limit will be limited to 60mm.
7. NEW for 2009: The Tamiya 540-J motor (53689) is the spec silver can motor for the 2009 season.
8. It is legal to use the maximum pinion gear size on all front-drive and rear drive Mini cars. I.E. 20-tooth on the M03 and 21-tooth on the M04.
9.Any Tamiya plastic or aluminum hop-up damper may be used.
10. Any Tamiya short or regular size hop-up spring may be used.
11. The use of LIPO batteries is permitted in this class, but due to the battery compartment having a rounded profile, the only legal LIPOs for this class is the Orion/Peak 2400, 3200, and 3400 Carbon Edition hard cased packs. Modifying the M-chassis to fit other hard case LIPO batteries is not permitted.
12. All M-chassis cars must meet a minimum weight of 1300 grams.
