12/31/2009. Remarks by Johan Visschedijk: "The seven brothers of the Jacuzzi Bros. company of Berkeley, California produced two aircraft, the J-7 Rio and the pictured single-seat Monoplane of 1920. The latter aircraft had a semi-monocoque fuselage and was built to investigate laminated wood construction methods. Powered by a 35 hp Ford T engine, the aircraft made a few short flights in 1920, but experienced major cooling problems.
Repowered in 1922 with a 50 hp Roberts 4-X and with a redesigned tail, the aircraft never flew again, on its first take-off attempt the propeller touched the ground and shattered, the resulting vibration shook the radiator loose; test-pilot Guy Coldwell escaped injuries. The company ceased aircraft production and became famous after WW II when they produced whirlpools."
