The AMA mis-spelled his name when he won Senior CL Scale at the '59 Nats. They listed him as "L. Burt Rutan" rather than "Elburt". Nevertheless, it was the same guy. Model was a Fairchild F-27, though I don't know the power or any other particulars. A photo appeared in an old magazine (MAN? American Modeler?) but it's long gone here.
Words is, later in life, he and his staff often flew RC models on the ramp in front of Scaled Composites (Mohave) during their off hours.
