I'm a beginner. I've started using a tach to set the needle before launch. Next, I need to start timing my lap times. I went to Amazon and nearly all the electronic stopwatches have the black numbers that virtually disappear in sunlight when I'm wearing sunglasses (brown tint) no matter how large the numbers are.
Very cool, Igor. I just ask Alexa, “time four laps when it’s inverted,” or “tell me when the motor is about to stop.”
