Found this so now all of you can compare what you ran with Donnie's car.   :D 

 

And I posted it before here: http://slotblog.net/...-two-old-races/ Is it still a senior moment if you forget to remember to forget to remember?

 

(Never mind, edited to remove bad links).

It was great seeing all the Pooch arms listed on the sign-up sheets. I'll bet Joel was in tall cotton in those days.

Odd that I searched the internet for this very race yesterday.

 

I was at the 74 nats but not the 75

 

three classes, Pro, B and C  

 

I dont recall the difference between the B and C classes????  something to do with qualifying?

 

I remember the change in wing control from the Camen wrap around to the thinner fold down setups.

 

Day after learning this new air control in San Antonio I put my car on the Odessa track and knocked off 1/2 second from the record.

The racing on our flat track changed substantially that day.

Classes were drivers ability. Amatures, semi pros and pros.

I believe it was still open motors. Later the c ran 15s and B27s

I recall running 20/7 (27) in Texas Series as early as 1972 in the Grp7 Open class.

 

HT could confirm if it was that early or not.  I do notice the absence of grp 20 arms on tec sheets.

Both 1974 and 1975 were Opens with 3 driver classes. I introduced 20/7 into the TCS as a way to get more racers involved by making the motors cheaper.

Didn't work, too much inconsistency in the arms. If you were short of power with Opens you'd just stick a faster motor in the car.  :D 

 

The air control thing was the watershed changeover from .010" side dams to .005" (after the Texas racers beat all the 1974 Nats records on the track when I started promoting .005" after the 1974 race).

 

I had a stack of .005" Mylar side dam material about 4" thick under the counter at the 1975 race and it was pretty much all gone by race day after the out of state unbelievers tried it.

Jim,

the 20/7 combination worked just fine in Odessa where I placed 2nd three years in a row TCS (tommy porfirio won 2 of those) with a NCC20 arm.  Of course the main straight was only 30ft so there's that.

 

obviously your 20/7 idea took hold when they started hand winding and tagged them 27.  when was that?

 

btw... about 15 yrs ago I ran into a guy who says he delivered your track labor day weekend of '66 from El Paso.  either boys club or ymca or some such with STAIRS.

 

ps thanks for posting that 75 Nats info.  I had to work that weekend but Doc Gibbs, Jim Boone, Danny Speegle, Phil Smith and Danny Katzman raced.... they all called me from a payphone after Katzman won the C class... he was crying... he was 13 years old too.  He is a scientist at Los Alamos Labs in NM

Rob,

 

The 27 class gradually developed here and there around the country in the Seventies as racers used chassis other than the original NCC Group 20 chassis.

 

AFAIK my 180' Engleman was initially set up on the lower level of Wonderland Mall in 1964, no stairs that I know of. Maybe another location in SA?

If anyone has a flyer for the 1974 nats - I've been searching a very long time.  Would appreciate a photo please!

 

Thanks,
