Hello all,
Does anyone have any info of the 1971 HOPRA race winning wind?
What AWG of wire and how many turns? Or how many feet of wire used.
Thank you

wasn't the first Nats in 75', won by Steve Brown?

 

If they were running G+ with rare earth mags, maybe a 36g wind?

In 1969 Carl Dreher, Kim Shaw, and a few others in Indiana came together and began the H.O. Professional Racing Association. Michigan crowned their first HOPRA Champion in 1970. Illinois HOPRA was created in 1974 by Mark Rosenwinkel and Norm Gardner. The first year of what became Illinois HOPRA, it was named Chicago-Gary HOPRA. Name was changed to Illinois HOPRA for the 1975-76 second season and has remained running ever since continuously to this day.

The first HOPRA Nats was in 1975 in Independence, MO.  From 1975-1977 at the Nats, all the cars in the pro main were AFX based pancake motors - Super II "Quadra-Lam" arms.  The cars are well documented with photos on the official HOPRA website at:
 
https://www.hopra.net/
 
Top winders of that era in Randy Kemp of K&K Racing, Joel Pennington and Norm Gardner.  Those three wound the arms on the winning cars at the 1975, 1976 & 1977 HOPRA Nats respectively.
 
No G-Plus cars in 1971.  There was no single National race yet in 1971.  Indiana and Michigan HOPRA series had started by then.  HOPRA East series also held in 1971. 
 
Most popular winds for pancake motors included single 36 of 38-40 double wind.

now I remember, I stop racing and started college in 75', but do recall that Gary B went to the Nats in 75', but was running the brass pan AFX that we were running out here in the west, but the lightweight AFXs were being run in the midwest.

I encourage anyone interested in this to review all the pictures on the HOPRA web site in the "History" drop down - "Nationals" tab.

 

H.O. Professional Racing Association (hopra.net)

 

There is a year-by-year inventory of a deep summary of each race, with wonderful material included.
