This cabin monoplane was designed by the american Hayden S. Campbell in the mid-1930s. Pretty modern twin-boom mid-wing in configuration, it was powered by a 82 hp Ford V-8 automobile-derived pusher engine. The Campbell F’s more interesting feature was its all-magnesium construction, specially its clean monocoque fuselage pod. Only one example seems to have been produced; it met its end during a demonstration flight.
Pretty obvious nickname’s origin.
