Thanks... i'm not sure if it's required to have the whole thing showing or what. I did it mainly to please the worst of all state troopers (pull ya over for anything!!) He ended up pulling me over one night saying that I was speeding thru town. I happended to be logging my fuel trims in dsmlink at the time and actually played the dsmlink log back for him to show my speed
Anyway, I got out of the car and showed him the plate mechanism I made because he pulled me over for no front plate before. He was totally cool with it, even though I trimmed the Wisconsin off the bottom. His exact words were, "At least it's there" He NEVER bothered me again about it.
If you have a FMIC, there isn't a whole lot of room to be mounting motors and stuff behind the bumper. If you run a window motor, how are you going to come up with the regulator? In otherwards, you're inside and you push a button. There would have to be some sort of a limit switch telling the motor to shut off. Servos are getting complicated because many of them work of PWM (pulse width modulation). You'd then need a circuit for that.
You might be better off with some sort of pneumatic air powered piston. Sometimes all the best ideas lead to an idea that will never get completed because of complication. That's why I just went simple. It looks good to the point where I don't mind have it the way it is.
