I couldn't afford a Shrike.....so I took an .049 motor and made a chassis out of an "Erector" set. (dated myself with DavidRoot on that one...) Lived on a street with a concrete curb/gutter. On street sweeping day noone could park on the street , so we ran our prop car down the gutter at about 40 mph. Between that and all the other things I did, It's no wonder all the neighbors wanted to thump on me.....man, wish I still had that car.....
