Episode 39 - "Oshkosh like a Pro!"

Flying to AirVenture in Oshkosh, WI in your own airplane is one of the great privileges and thrills that pilots have, and to arrive in a homebuilt plane is even better.

We discuss our best tips to make the planning and execution of your trip run smoothly, and help you navigate the experience like a seasoned AirVenture attendee.

Episode 37 - "AeroVee Assembly and Operation Tips"

The AeroVee engine is a great, affordable engine option for your Sonex project. The AeroVee is an “engine kit” and requires builder assembly.

We discuss these areas with several experienced AeroVee engine builders and pilots, and present tips to ensure your engine is built right and performs reliably for years to come.

Episode 36 - "Vinyl Wrapping"

Traditionally, the choice of Sonex finishes has been paint or polish, and each has their own merits. However, there is a new option that is lightweight, cost effective and fairly simple, using adhesive vinyl sheeting. Several Sonex airplanes sport this finish, including both John Gillis and Mike Neidenthal. John is a certified 3M applicator, and will tell us all about using vinyl wrapping on your project.

Our friends in Australia are busy building and flying their Sonex aircraft, and are doing some pretty interesting things.

We’ll describe how to make your turtledeck look like it was built by a pro.
