New here and to the RC hobby. Building a pinewood derby car with a 40mm EDF. Have a BLHeli 30A esc and a 3s, 450 mAh 30C battery. Want to use a servo tester in place of a receiver and install a normally open switch in front that will be closed when the start gate pin is in the up position and the car is resting against it. I would like the fan to start as soon as the pin drops. Where in the circuitry would be the best spot to place the switch?
