Do you have some HOPRA history  to share? Send us email!


Over 45 years, we at HOPRA have been scheduling races and championships to give race fans and H.O. enthusiasts the opportunity to become more involved with scale auto racing and add to their enjoyment of racing and H.O. cars.


Established in 1969, HOPRA has been dedicated to the promotion and advancement of H.O. slot car racing. We run many state championships and larger races throughout the country. Starting in 1975 and every year since, HOPRA has held its annual National Championship event that draws the best H.O. slot racers from around the world. This page is dedicated to the history of our origination. 

The birth of HOPRA - 

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 birth of the HOPRA National Championships - 

Tom Coyne, of Otisville, MI and the owner of TCP, was the primary driver behind the first nationals in 1975. There were a few others that helped him, but he was the primary leader. From the second nationals, Mark Rosenwinkel ran the National event along with Norm Gardner for many years. There were individual Race Directors in the host city each year, but the responsibilities around selection of track and cities fell to Mark by default at the national level.  A lot of trust, handshake agreements and yes, some stumbles along the way.  Rules evolved and a lot was just by general consensus. There certainly were rocky roads along the way, but the race and the HOPRA organization  survived and the race took place every year and grew. Mark brought the leaders from across the country together at the 1979 Nationals in Detroit, MI and laid out the organizational plan composing including a National Director and senate seats representing various states. This was approved overwhelmingly and Mark was elected as the first formal National Director. He served consecutive terms from that point in 1979 through 1982. Throughout the years HOPRA has expanded on this foundation maintaining the original structure set in place by the founders of our organization.
