Hi,lets look at attempts by some manufacters to bring realism to the slot car race. In real life you would run out of gas at times during the race & so you had to make a pit stop. Well these 4 companies tried it but i dont think it was successful.After all we want to go fast not stop for gas.We hate it when we are in our real cars & have to stop for gas.Plus when racing ,we dont like going off the track because it also interrupts the race.1st we have the Scalextric version,their "fuel gauge".One might want these cars to come to a stop so you could see how pretty they were.2nd we have the US company Gilbert. Here you take the car off the track & put it on the pit stop to refuel. I think even the young kids who played with these cars quickly grew bored with this accessory. They dint want anything to interrupt the car crashes.3rd we have the nicest made pit stop of all by the German company Stabo.You wound up the gas pumps & the fuel gauges turned . Now i might even like stopping my race car just to operate this system.4th & last we have the Carrera Tempo 1/60th scale pit stop. You simply put the fuel right in the car just like a real one & like your real car it slows you down toward your destination. Not to mention the cost.
