Construction Slated on David Heerensperger’s Turbine-Powered Pay ‘n Pak

Jet age Unlimited hydroplane expected to make debut in 1980.

Seattle, Wash. – Construction on David Heerensperger’s turbine-powered Pay ‘N Pak Unlimited hydroplane is expected to begin early this spring. Project manager Jim Lucero unveiled a scale model of his newest design, a streamlined cab-over with a front spoiler and a rear stabilizer wing. Built of lightweight aluminum and wood, the jet age Pay ‘N Pak is expected to race for the first time in 1980.

Lucero will soon begin extensive modifications on the helicopter engines that will power the low profile Pay ‘N Pak. The turbine engines selected by Heerensperger and Lucero are expected to considerably reduce the long term engineering and maintenance expenses for Unlimited hydroplane teams.

The Unlimited Racing Commission, A.P.B.A., has granted unrestricted clearance to the turbine project for testing and competition for four years beginning with its first race.
