AirVenture, the world's biggest airshow in Oshkosh, WI, is less than two months away, and it’s time to get busy finalizing plans for attending. We cover flying in, camping and lodging options, airshow events and more in our 2019 preview.

The Onex is Sonex Aircraft’s single place sportster, being roughly 80% the size of a Sonex and offering more speed and even snappier handling. Onex’s are appearing in the completions gallery more and more, and for good reason! Our guest owns both a Sonex and a Onex and is particularly well suited to describe the similarities and differences the Onex shares with the rest of the fleet.

Electronic Fuel Injection (EFI) is a popular addition to experimental aircraft engines, and offers several attractive benefits including balanced mixture distribution, lower fuel burn, increased power and general smoothness of operation. We discuss the SDS EFI system with a successful Sonex builder and the company founder, and lay out what you'll need to add EFI to your AeroVee.

Now that winter has finally retreated and spring flying weather is here for most of us, it’s time for many new projects to make a first flight after being completed during the winter building season. We discuss the important considerations to prepare yourself, prepare the airplane and refine your first-flight plan.

The SonexFlight Podcast is coming up on its third anniversary, and it’s probably past time that we formally introduce ourselves. Your hosts talk about our own aviation backgrounds, share the stories that brought us together on the podcast, and look ahead to goals and objectives we each have in the coming months.

Most Sonex pilots are flying engines that utilize permanent magnet alternators, such as the AeroVee and Jabiru. These systems are simple and effective, but can benefit from a carefully constructed electrical system that incorporates active voltage protection. Our guest Bob Nuckolls helps us dig into overvoltage protection to explain some simple practices we can use in our planes.

Now that winter is fading and flying season is kicking off, it’s time for us to have a look at our planes and get them ready for the season. Smart pilots will pay particular attention to the health and care of their engines. We review the common maintenance items that a pilot will need to consider, and offer our insights to keeping things running smoothly.

Garmin’s new G3X avionics system is targeted to the Experimental and LSA market segment, and offers a lot of bang for the buck. We sit down with Garmin to dig into this system, explaining what you’ll need for your Sonex and how much it will cost to get state of the art capability.

The Rotax 912 is a common engine choice for LSA and sport aircraft, but until just recently has been absent from the Sonex fleet. With Sonex Aircraft now supporting that option, builders are increasingly flying behind Rotax power. We speak with one of the first Rotax-Sonex pilots about his engine installation, and offer some insight and advice to pilots wishing to choose that engine option.

Drilling the wing spars to the fuselage is a final step in completing major assembly of the airframe, and may cause builders grief if not done correctly. We explain how to rig the wings accurately and painlessly, and avoid the need to remake parts from a wing rigging operation gone wrong.
