the electronic signal would be fairly easy when you stop to think about it. it could be run like some of the cars these days. they use magnetic sensors to measure the speed. sheet medal and paint is easy. i was thinking of hiding it behind the grill but with the performance oriented motor im going to need all the air i can get to it. i think getting it close to the windsheild is a good idea but now that im thinking about it it would be kinda cool to make the pnumatic raising hood scoop. even if i had to go against the idea of using speed to lift it. all else fails i do a quick job using servos and a few small motors.
