I would like to inquire as to when and how the different "Group" series began please?
 
For example, I have seen: "Group 12 - Group15 - Group 20 - Group 22 - Group 27" mentioned, and recently came across Group "F".  Pardon me if I missed a few!
 
From my understanding, these groups are "Wing Car" related - please correct me if I am mistaken!
 
So, if anyone can provide some history on how these "groups" were born, and the differences between them, that would be greatly appreciated.
 
Thank you.

Group 12 dates way back to 1969-70 whereby your car purchase could not exceed $12.  Arrow down on this article for more details on how group racing evolved.

The group identifications predate wing cars.

 

The first one I remember was Group 20 about 1969. The car could cost no more than $20. It had a spec motor and chassis. Champion sold them along with others manufacturers. That was about the time I got drafted and everything changed.

Yeah, I remember G20 first followed by G12... 1969 sounds right; as mentioned, the number had to do with the max cost of an RTR.

Mura (green can) NCC 20 motors. Best thing that ever happened to slots, as a young boy, 1969. Made me competitive at a reasonable cost.

I noticed on an epay champion of Chamblee item the other day that showed group 30 and group 40

 

other than higher cost? what were the rules for those 2 groups?

dunno..... never heard of 'em..... must've come along during my long hiatus from slots, 1973 - 2006

Group 40 arms were out in the 1971-1972 era, they were wound with 26 gauge wire and were very respectable on short tracks. I still have one that was competitive as any open of the day on an Orange track, the ones with the humps down the straight that required a blip to not launch.

I know Champion listed Group 40 in their 1977 catalog. Not sure about Group 30. Will have to dig around and find my old catalog.

 

BTW, what is the difference between a Group 20 arm and a Group 22 arm made in the early 1970's. I know what a group 20 arm is today. I want to know about what they were 45 years ago. I was out of slots 1968-1978 or 1979.

The group 22 I had (1975?), had the same wind as my Champions and muras. The differance was the winding was done by Camen and looked like a group 7.

My Grp.22 arms were wound by Bill Steube. I have one Steube arm tagged Grp.20. I don't recall if its timing or winds differed from the Grp.22's.

There's some info in this thread, including a recent post from Jim Honeycutt, where he came across a Group 40 arm;
