Arnold AR-5

Originally conceived by Mike Arnold as a personal sport airplane with excellent performance and good handling qualities. The design outperformed initial performance estimates for its relatively low power output, exceeding 200mph with only 65hp.{{Cite web|date=2016-10-20|title=Prologue - Mike Arnold and the AR-5|url=http://www.ar-5.com/images/sportsmanpilot1.PDF|url-status=live|access-date=2021-11-22|archive-url=https://web.archive.org/web/20161020013923/http://www.ar-5.com/images/sportsmanpilot1.PDF|archive-date=2016-10-20}} Constructed of fiberglass-epoxy matrix composite material utilizing the "moldless method" popularized by Burt Rutan.{{Cite book|last=Factory|first=Rutan Aircraft|url=https://books.google.com/books?id=eRyiMwAACAAJ|title=Moldless Composite Sandwich Aircraft Construction|date=2005|publisher=Aircraft Technical Book Company|isbn=978-0-9774896-1-9|language=en|access-date=2021-11-22|archive-date=2022-03-04|archive-url=https://web.archive.org/web/20220304214310/https://books.google.com/books?id=eRyiMwAACAAJ|url-status=live}} Careful attention to aerodynamic detail resulted in noteworthy laminar flow drag reduction, as documented by aerodynamicists Alex Strojnik and Bruce Carmichael.{{cn|date=September 2023}}
