When the race comes to my house in August I'm going to break out my Radar Gun I bought for my RC cars and trucks. I'll award the car that clocks the fastest Real MPH on my long straight, one of my custom, never been run, repaint, DSlot43s. This prize only applies to cars that are entered for the races.
It's a Bushnell and works very well...I'll get the MPH after the races are run so there is no interference with one of my sons leaning over to line up the gun with the track. I'll take the best speed of 3 tries. R4 180 turn leading onto 24' straight timed at around 18'.
