Active Rear Wing Control System. Help Needed

[maddox10]

The 12 volt supply ain't an issue. Replace the extra lead battery with a LiPo pack of the same weigth, and a 6s psck is cheap and rechargable with a equaly cheap and light charger that happely will use the on board 12volt supply.

But yes, you're right Nick, a normal linak is artritic slow for this purpose.

With only 3 positions I see a solution with 4 solenoids.
How fast is an Arduino? The speed of a mosfet is known and more than fast enough.
This also solves the sync issue.

Some Arduino boards are faster than others; I have never used them but there are ARM 32 bit Arduinos with serious processing power like this: https://www.sparkfun.com/products/11589

I don't know if solenoids would have the power to shift the wing while the car is in motion - I recall hearing that F1 car wings generated enough down-force to allow the cars to drive upside down, so a touring car wing must generate hundreds of Kg of down-force.
