The RLU-1 Breezy is a homebuilt aircraft known for its "no cockpit" high wing pusher configuration. It is designed to seat the pilot and passenger with a maximum unobstructed view. Designed and built by Charles Roloff, Robert Liposky and Carl Unger, the original Breezy used a modified set of Piper PA-12 wings. Wings from the Piper PA-14, Piper PA-18, Piper J-3, Piper J-4, Piper J-5, or Cessna 172 can also be used on the design. Designer and pilot Carl Unger flew thousands of passengers for free in his Breezy prototype. The aircraft is now part of the EAA AirVenture Museum collection. At the 2014 EAA AirVenture Oshkosh there was a series of special events to celebrate the 50th anniversary of the design, including a fly-in of Breezys.
