I've actually decided to scrap the electric motor and make a hand crank instead

The motor is far too bulky and obstructs my view no matter how I mount it

Besides, I don't really plan on driving in the rain and the last 3 downpours I got caught in really didn't affect the flat windshield much for some reason (and I have yet to put Rain-X on it)

I figure a hand crank will be easier to conceal as well as a neat conversation piece
