First race 1895
Peak - 62 years later
and now we are 63 years beyond it!

Never did anything like that but it called to mind my days of hanging on by my toes over the rail of a 17' racing dinghy. A beam reach in 20 kts of breeze was a drenching experience.Jenks with Marcel Masuy at Solitude, 1952, competing with their Norton-Watsonian. This is just one reason why Jenks was so infuriatingly intransigent in his views about safety in motor sport.
Weight shouldn't be too much of a problem - consider the sound output of cell phones and it would be easy to link pitch to power applied but upshifting, downshifting and overrun - a bit more of a problem.Which raises the question of why digital slot cars don't have sound, like many of their rail -borne digital counterparts?
Perhaps because the weight of the sound chip and speaker would degrade the performance, which isn't really a problem in the model railway world?
