The SONEX is a basic and economical all metal, two place aircraft designed by John Monnet,following on from the successful Sonerai series. It can be built as either a tail dragger or tri-gear and, ideally for Australian builders, it can be fitted with either the 2200 or 3300 Jabiru engine. The Sonex can be registered (19-xxxx) and operated as an “AUF Amateur-built (Experimental)” ultralight in Australia. Straightforward metal construction combined with an enviable performance give us a remarkable aircraft for amateur building in the ultralight category.
I had been watching the Sonex since the original concept and building of the prototype. It has since has exceeded all my expectations as a high performance and easy to fly sport aircraft, so when the time was right for amateur building as an ultralight, I committed to the project and purchased the component kits and engine. Have a look at the links below. I hope that the information and photographs in these pages is useful for prospective amateur builders of any design, but perhaps particularly metal construction.
