"Bluto". In 2001, the first Bluto prototype was created. It was designed by Harris to test the efficiency of a straight leading edge plank, with no fuselage. To our knowledge, it was was the first "Delta Nose" concept plank to be on the market. It won its debut SCSR race (above pics), on the maiden voyage in Tehachapi, CA, and was a 54" twin-fin, with a straight LE, three servos (separate, central driven elevator), and...shutter... packing tape covering!
