There has been a bit of mis-information (alternative facts?) spread recently about dynamic propeller balancing. Here's a link to an article written by Brian Rebbechi for the SAAA's "Airsports" magazine which should help clear things up a bit.

Alternate Canopy for Sonex/Onex
Ian Linke from South Australia is seeking comments/preferences regarding an alternate canopy for the Sonex fleet.
He is interested in making either a single piece or two piece as per current design.
Canopy promises to be better quality and made exactly to the airframe dimensions, therefore easier to fit.
You can read/post comments on the
website or contact Ian directly via email (preferred) or phone.

I got a nice surprise in the mail a couple of days ago. While the Sonex builders and fliers were dining at the Narromine Hotel. There was an official dinner at the aero club where they were handing out these.

Ozkosh at Narromine 7th to 9th October
There were only two Sonexes at Ozkosh, although there were a few builders and non-flying owners there, and we managed to get together for a very enjoyable dinner at a pub on Saturday night. The weather forecast kept a few people home and if anyone had come from South Australia they probably would have had difficult conditions on the home run. Those that drove had a pretty long trip because of detours around flood waters. There was pretty good attendance by SAAA and RAA aircraft but no war-birds and only a couple of vintage aircraft which was disappointing.
Cliff Jarvis displayed some samples of a range of clothing, polo shirts, jackets and caps, all with the Sonex Australia logo. They look great and I hope he will have something on this site soon.

What happens when too much spare cash meets excess spare time - a Merlin motorcycle
Everybody was pretty anxious to get away early Sunday because of threatened turbulence, but I had a good flight home with smooth conditions at 4500 ft and a gradually increasing tailwind as I flew South so that for the last 100 miles the ground speed was around 150 knots. When I descended to circuit height at Kyneton the turbulence was severe, the roughest I have experienced. Fortunately the wind was straight down 36 but it was still a difficult landing. Didn’t need to use any power to back-track the runway as the Sonex was getting blown along by the strong wind, in fact I had to hold it with the brakes to keep the speed down.
August 2016: VH-BST back in the air with a new CAMIT 2200 engine
My Sonex has been out of the air for 18 months, and giving trouble for several years before that. Now back in the air with a CAMIT 2200. Major mods to cowls allowed me to use the CAMIT supplied ram air ducts without changing them to suit the tight Sonex cowl. Result, nice even cool heads. Key stats: 2850 rpm, 115kts, 600fpm climb. At cruise 1350EGT 220CHT. Running a 54x54 Sensenich prop. Runs like the proverbial swiss watch! That CAMIT alternator is a tight fit under the fuel filler.

Kyneton to Rockhampton in a Sonex
If you ever thought that a Sonex was too small to do useful long flights, here's a link to my blog on a flight from
Kyneton, Victoria to Rockhampton, Queensland,
a distance of 930 nautical miles. The photo below shows the estuary of the Fitzroy River, just south of Rockhampton. For part 2 of the trip visit
Rockhampton to Kyneton
, my 970 nautical mile return trip. I really enjoyed the trip and I'm looking forward to trying something a bit more adventurous.
SonexAus Annual General Meeting
I have to confess your SonexAus Executive Committee have been very slack over the last couple of years. We failed to have a proper AGM for the 2014 calendar year, but have cobbled together enough information from an informal meeting in Yarrawonga to lodge our annual return to Consumer Affairs Victoria for 2014. Now we need to have an AGM for the 2015 year, and a few dedicated souls have agreed to link up for an AGM on
Wednesday 29 June 2016 at 8pm EST via Skype. If you would like to participate send me an email and I will forward a link. You need to be a Skype member, but it doesn’t cost anything. Get it set up well before the night.
Yarrawonga Update 4/5 June
We were defeated by the weather on this weekend. It was fine in SA but got progressively wetter towards the east. Rumour has it that a bit of rain fell on the east coast.
The Rumours were true! - first flight by Paul Westman's Xenos
Paul has completed and flown his all flush-riveted (that's a lot of dimpling) Xenos.
AAAA (Antique Aircraft Association of Australia) Fly-in Echuca, April 2016
No fewer than five Sonex variants made their way to this fly-in. The Sonex doesn't qualify as an antique of course but a few of the owners did so we were most welcome. Those flying in were: Greg Tabe in the new South Australian Sports Aircraft club-built Sonex, Chris Dearden in the Xenos from Goolwa, Tony Richardson from Callington, Brian Ham from Mangalore and Peter Anson from Kyneton.
The SA club sonex was being antisocial and Brian Ham's Sonex was PARKED IN A HANGAR! Come on now Brian, that's not what we do at fly-ins.
I feel pretty good about myself for building and flying my own aircraft, but the work put in by some of the aircraft restorers really puts things into perspective. They were just beautiful. They included a good range of warbirds and a couple of beautiful old passenger carriers. Here's a

First flight report
Phil's Bird flies!
Phil Bird from Mittagong NSW took to the skies recently in Sonex 759.
Congratulations Phil !
First Flight report:
Screenshot from Phil's photos posted here:
Previous first flights by Michael De feyter - see his
first flight on youtube.
(Michael's Sonex is #145 - there must be a story behind that) and more recently, the tri-gear Aerovee-powered Sonex #r 1631, built by the Sports Aircraft Club of South Australia. I think that Chris Dearden and Steve Nelson (Xenos #35) might have had a bit to do with that one.

If it flies half as well as it looks it should be a great little aircraft
Kyneton to Mount Gambier Dec. 2015
Only a short trip but there are a few photos of big holes in the ground for the geographically inclined.
Ausfly - Narromine, September 4,5 and 6
There were five Sonex aircraft at Narromine. Those who made it were Ian Mitchell from Benalla, Brian Ham from Mangalore, Doug McLean from Goulburn, Steve Woodham from Port MacQuarie and Peter Anson from Kyneton. There should have been six of us but Keith Jeffs had a major taxying oops at Griffith and had to complete the journey by car, a pretty gutsy effort in itself. It was a good chance to catch up with people and we witnessed a good airshow. My favourite was Paul Bennett flying a Wirraway. Who'd have thought you could throw an old aeroplane around like that? It was capped by a great display of precision aerobatic formation flying by the Roulettes. A couple of their fast break manoeuvres had the crowd gasping. I managed to fit in a hangar visit to Paul Westman at Temora on the way up. Paul is doing a very nice job building an all flush-riveted Xenos. I think he's just about at the 90% down, 90% to go stage. As a bonus, I even had a light tailwind both ways.
Hmm....must polish my wings
Heading home from Narromine.
Lake Mungo Fly-In 8/9 August
This was a fairly exclusive affair but enjoyed by all who attended. We opted for fairly Spartan dormitory accommodation, but lounged and dined in luxury in the Mungo Lodge, where a large open fire burning mallee stumps was part of the attraction. I'd recommend the Mungo Lodge for a flying visit. The service was efficient, the meals delicious and the atmosphere welcoming. Checkout Richo's report at

VALE Jeremy Monnett
CEO of Sonex Aircraft and son of the Sonex designer John Monnett, died in an accident at Witman Field Oshkosh on 2 June 2015. Sonex builders will know him as a friendly voice at the end of the phone or email, ready to provide advice and assistance. Jeremy was a 'force of nature', a bundle of fantastic enthusiasm and an inspiration to the wider Sonex family of owners and builders. Our thoughts and prayers are with his parents, John and Betty, his wife and family, and all associated with Sonex and experimental aviation. He will be very sadly missed.
A crisp winters morning, 3500' over the South Australian countryside, on my way to the Sunraysia Sportsaircraft flyin. RIP
Saturday 2 May 15 saw four Sonex aircraft gather at Yarrawonga under calm blue skies.
Doug Mclean from Goulburn, Keith Jeffs from Ballarat, Brian Ham from Templestowe and myself from Callington SA.
There to greet them were the intrepid drive-in attendees Cliff Jarvis, his friend Jim and Peter Anson. (who is rumored to love driving his Mum's old car so much, he left the Sonex at home)
It was good to catch up with all and have a look over the other aircraft, especially since I hadn't seen Doug's or Brian's up close before.
Brian wasn't staying overnight and departed later in the afternoon.
Catching a lift with Peter, we retired to the Bourkes hotel for our overnight stay. Rooms were comfortable and light breakfast thrown in.
After a few drinks in "Bourke's Front Bar.." could that be a song?), the six of us joined the Megafauna Fliers at their pre-departure dinner.
Dinner was very nice after a long day, although I'm not sure about Keith's cholesterol levels after seeing the mixed grill piled on his plate!
After dinner we were regaled with tales of Megafauna derring-do and general mayhem by Peter McLean.
There was also video evidence of this from the 2008 Megafauna trip. Looked like a lot of fun.
I got the feeling we should have been tagging along on this trip instead of heading home the next day.
Sunday morning it was time to preflight, repack and refuel for me before heading off. Weather was perfect with calm winds on the ground and a smallish headwind for those heading west.
I taxied down to the caged bowser tanker thing as aircraft departed overhead, along with a few of those mossie trike things.
Luckily the refueller was coming through the gate as I made my phonecall so I didn't have to wait long until I was ready to go.
I arrived safe back at Callington with 4.6 hours on the Hobbs.
PS for more details on the flight over :
Dougs 2200 Sonex. Nice paint, nice rego Doug

Peter McLean at Yarrawonga has obtained a supply of Sonex tyres and tubes (11x4.00x5) for us and has them in stock. Support your local guy and contact him for your tyre needs. He is hosting a fly-in for us 2-3 May 2015. Contact him at
for details of the tyres.
