Home – Sonex aircraft parts


About Peter Anson

Ansoneng.com is essentially me, Peter Anson. I am a former engineer, motorcycle dealer, school teacher and engineer (again).  As an engineer I have been mainly involved in structural testing of aircraft parts as well as complete aircraft, but I didn’t start flying until about 15 years ago.  Since 2012 I have been flying my own home-built Sonex, which took me about 6 years to build from plans.


The Sonex is great fun to fly, especially when powered by a Jabiru 3300 engine.  I highly recommend the Sonex.  It is light, strong, not difficult to fly with a low stall speed and good control feel, and it is fairly straightforward to build.  It isn’t in the class of a Vans RV7, but then neither is the price.  During the course of the build, and since, I inevitably came across some minor aspects of the design that I wasn’t entirely happy with.  In the “Products” section I’ll present some parts that I have found to work particularly well.

How strong is a Sonex?

The answer is, pretty strong, but not as strong as you might think.  Those massive wing spars do have a weak point.  In the linked article I make the argument that overloading the Sonex (or any aircraft really) will reduce its fatigue life.  What is the fatigue life of a Sonex?  I have absolutely no idea, but it isn’t infinite and increasing the AUW of a Sonex by 100 pounds will more than halve the fatigue life.

Recent changes to my own Sonex

I built my Sonex with the standard 30 degree angled instrument panel but was never happy with the viewing angle on the MGL Stratomaster monochrome panel.  Making a new vertical panel and glare shield looked likely to be a lot of work so I decided to do a fudge fix, and here it is – a spacer block which sets the Stratomaster at 15 degrees to the panel.  Spacer was 3D printed.  Print time was about 10 hours.While I was at it I added a hood to shade the screen, and below is the installed spacer block and hood.I think it looks pretty good and prefer the new viewing angle but would like the hood to be a bit deeper, but if it extended further the hood would probably best be made of rubber.
