The 69 Mustang used was not a Boss mustang. Has the faux air scoops on the rear quarters.

BTW, I think they ought to allow the HPI Corvette body too with ONE stipulation. It must run "AP" or "BP" (A/B Production) markings. They should also change the rule for the 65 Shelby Mustang and require it to run "BP" (B Production) markings since Shelby removed the back seat and stuck the spare tire where the rear seat goes to run it against B Production Cobras and Corvettes along with European B production vehicles. These cars regularly ran with A Sedan cars and in some cases TA cars at smaller regional events (A Sedan and Trans AM were basically the same class with the same rules. A Sedan was more of the local and regional races vs the Trans American Series which was the National Series).

A & B Production class cars as of 1972:
Class A
Abarth Simca 2000
AMX Sports Coupe (360) 1970
AMX Sports Coupe (390) thru 1969
AMX Sports Coupe (390) 1970
Corvette Sting Ray 350 Roadster & Coupe 1970-1971 (LT- 370 BHP 350)
Corvette Sting Ray 396
Corvette Sting Ray 427 thru 1967
Corvette Sting Ray 427 Roadster & Coupe 1968, 1969
Corvette Sting Ray 454 Roadster & Coupe 1970, 1971
Ford Boss 429 Mustang 1969. 1970
Griffith 200
Porsche GTS 904
Shelby Cobra 427
Shelby GT-500 thru 1967
Shelby GT-500 Coupe 1969

Class B
Alfa Romeo Montreal
AMX Sports Coupe (290) thru 1969
AMX Sports Coupe (343) thru 1969
Corvette 283
Corvette 327 (1962)
Corvette Sting Ray 327 thru 1967
Corvette Sting Ray 327 Roadster & Coupe 1968
Corvette Sting Ray 350 Roadster s Coupe 1969-1971 (Not LT-1)
Ferrari 275 GTR Berlinetta
Ferrari 365 GTB 4 Daytona
Jaguar Series 3 E V-12
Porsche 911E Coupe/Targa Cabriolet 1969
Porsche 911S Coupe/Targa Cabriolet 1969
Porsche 911E Coupe/Targa Cabriolet 1970, 1971
Porsche 911S Coupe/Targa Cabriolet 1970, 1971
Shelby Cobra 289
Shelby GT-350 thru 1966
Shelby GT-350 1-4V, 1967
Shelby Cobra GT-350 Coupe 1969

You will notice most if not all of the production classes are denoted by not having a back seat. A Sedan and Trans Am cars all originally came with a back seat (Reference the AMC Javelin vs the original AMX. The only difference in these cars was the Javelin had a rear seat and the AMX did not and the AMX had a 12" shorter wheelbase to make it turn better).

Man' its bad when you're old enough to actually REMEMBER this stuff.

Love your list of shells, but nobody makes most of those and you just made it really complicated.

You would think that as technology comes along with new 3D scanners and 3D printers, that someone would have a little shop where they could do short runs of the cars we are looking for. The missing year models and favorites.

Snoopyrc,

That's not a list of shells. That is the list of cars allowed in A Production and B Production SCCA class racing as of the July1, 1972 revision of the 1972 SCCA Production Car Specifications guide. I could also include the C through H production list but the whole list is 3 pages long and the detailed specifications covering everything is 144 pages.

Hey Sharpie, Someone mentioned on here about a possible temp sensor in the motor that connects to Novak esc's through the sensor wire. They said to pull whichever pin it is out from the motor side of the sensor wire. I don't remember who described it, but they said it made it work with the speed passion esc's. Might check into this theory to see if it has any truth to it.

If snowbirds runs ROAR rules you can run any size 2S battery. If they run USVTA rules then you have to run a 5000Mah battery. Either waay I would suggest getting one from Eric Anderson of EA Motorsports at www.teameamotorsports.com. He has an awesome 5000Mah 70c VTA pack that is unbelievable. Mine holds above 8v all the way through a run so it has great punch until the end. He also has a 6500Mah 70c pack that I run in 17.5 sedan and it is crazy fast. It also wil stay above 8v till the end. You cant go wrong with his packs.

I got it all hooked up, pulled the 2nd pin from left on the motor side of the sensor wire ( blue strand ). The motor worked flawless here at the house. To better test it I unplugged the motor fan and ran it up n down the hall til it reached 140* and it never showed any starting problems, seemed to have better brakes tham my Edge ESC. I used a spare sensor wire, took a hobby knife and pushed the blue wire pin out of the connector and taped it back against the cable, that way I can reuse the sensor wire at a later date by snapping the pin back in.

I am confident that the sensor wire mod fixed the problem, will know friday when I put it thru the ringer at ThunderJam5

I second that. Very good packs. I run them in my VTA as well.

5000mah is just the upper limit.

Battery Specifications: 2 cell LiPo hard cased, 5000 mAh limit


I run a 4400mah shorty and have no issues. Helps with the weight.

I know it's a bit off course but having been mostly an oval racer, I did get a chance to run the VTA car on the oval Friday night and had a blast. Actually was more fun to drive than my SK Mod or Outlaw Truck! Did not change gear or suspension just threw it down and ran it. It was slower than the oval cars but the weight and tires made it more realistic than I have experienced with R/C in some time. I had to back up the corner and wait on the tires to grip before getting back on the throttle to get off the corner. If I got too greedy with the throttle it would step out a little too! When we get back to Minnreg, I'm in if anyone wants to also run 'em on the oval day. I would suggest to minimize the urge to make changes we go with the straight up USVTA spec.
I had watched USVTA at the 'Birds for the last several times they were run and decided last year that I was going to join in. Although I've never been too keen on the TC platform, I thought it would be something neat since I liked the looks of the bodies in use. Now as I get my gear ready I find that the VTA car is by far the least complicated car in my stable. Basically I've had motor and tires ready for over 6 months! Good thing because we're less than 2 weeks out and the other oval cars are bogging me down with the motor deal and prepping tires choices and options. I liked it before but I'm really liking this VTA idea more and more.

I also run one of Eric's 5000's in my VTA car and one of his 6500's in my USGT car. Great lipo and good guy to buy from.

According to the 2013 Snowbirds Rules, they are using USVTA rules. That means everybody (in VTA) must have a driver figure, a number on both doors, hood and trunk, a 5000mah Lipo max, a USVTA-Legal ESC and 1 of the 2 Novak 25.5 motors in their car.
