Take a Ride In a Thorp T-18


Join Phil Mandel for a walkaround description and a brief flight in his Thorp T-18 homebuilt, one of the most affordable high-performance homebuilts on the market. Designer John Thorp was part of the Piper Cherokee design team but this was among his favorite projects.

Be sure to read about Les Krumel’s Thorp T-18 in One Piece at a Time.

  2. What a great job you did with the video. It would be fun to see you do a cross country video in that beautiful airplane.

  3. This is a great video that brings back memories. My uncle was one in a group of men who built several Thorp T18s in Michigan back in the early to mid ’70s. He and his wife flew his T18 to Utah for a visit, and I was introduced to flying small aircraft for the first time. In spite of a probable wind shear that caused both our heads to hit the canopy while I was in control of the aircraft, I fell in love with flying! Thank you for stirring a great memory.
