Throughout 1969, Super-Chargers provided “lap after lap” action. For 1970, Rod Runners were added to the circuit scene. The basic track consisted of a single lane Rod Runner powering an oval layout.
The 1970 Hot Wheels Rod Runner Speedway Set includes 16 feet of orange track, 8 joiners, 2 full curves, 1 single lane Rod Runner and 3 white trestles.
The main difference between Super-Charger and Rod Runner ovals is car action. Super-Charger circuits automatically space the cars out evenly. That’s the nature of a battery powered system. When 2 cars start getting close to each other, the second car receives less power because of lag time in the spinning Super-Charger wheels, so the second car falls back. It’s quite unlikely that a Hot Wheels car will catch up to the car in front of it. But a Rod Runner is elastic band powered and shoots cars out with equal force no matter how close they get to each other. So it is very likely that the faster car on the track will catch up to and rub bumpers with the car in front of it.
Here’s the track layout on paper and on the floor.
Ready for a lap.
Into the Rod Runner and blasting out.
Up and into the elevated first curve.
Out of the curve and heading for the hill.
Up and over the back straightaway trestle.
Into the second curve.
And back to the Rod Runner.
Here’s my video of 2 Hot Wheels cars running the single lane Rod Runner oval.
So there you have it. The 1970 Hot Wheels Rod Runner Speedway Set.
It’s still fast. Still fun.
