Engine startup
This was our 3'rd startup of the engine. We now have most engine parameters working on the iEFIS and we never saw above 95 degrees CHT's. At idle the CHT's comes back down, so cooling seemes to work fine

Project status
Greetings all. It has been more than a year since the last update on this home page. I guess we've all battled the consequenses of Covid, but now (hopefully) we've seen the worst of it and are looking ahead.

Since my last update, we have relocated the project to a different location. Our former workshop was on loan only, and the owner of the shop had other plans. Fortunately, my garage was big enough for the fuselage, hence it was moved there. All though a great deal smaller, my garage is next to my house and it has payed off in progress.

All electrical systems have been completed, engine installation/firewall forward is completed, and fuel system is complete.

We've had a bit of a struggle with the communication between engine ECU and the MGL iEFIS screen. Most issues have been solved, only fuel pressure still not showing correct value.

We've had the fuselage on the outside and started the engine 3 times. First time was to see that the engine actually worked. It started after a few blades and ran quite nice. We did however find a fuel leak. On the second start, we realised that we had a cooling issue.
Both fuel leak and cooling issue sorted making the third start a success.

Several build sections of this site is updated, you're all welcome to have a look.

Introduction

This webpage is dedicated to our joint project of building a Sonex experimental aircraft. 

We are four old friends who decided to start this project together. We bought a tail kit from another builder here in Norway in January 2012 and started construction soon after. We decided that if we could get the tail section completed, the joint project was something we could complete.

Needless to say, we soon realized that there was no turning back. So, after getting our project application approved by Norwegian Aviation Authority (project no 320), an order for the rest of the kit was placed, and a large box was delivered to our workshop in July 2012. Cristmas came early that year.

The aircraft is a small two seater constructed from a kit made by Sonex Aircraft LLC. Check our links page to visit their homepage. LN-SNX will be configured as a tail dragger, with dual controls. Our engine of choice is the UL Power 350is. The design is aerobatic, +6/-3 G. However, we do not have an inverted fuel and oil systems, so the aircraft will be limited to positive manouvers.

The serial number of our kit is 1571, meaning there are at least a corresponding number of kits sold as per summer 2012. The line of kits from Sonex LLC have grown in popularity, and they are currently being built and flow world wide. In Norway there are, as far as we know, five other Sonex'es. They are however all in Ultralight category, ours will be the first built and registered in the Experimental/Amature Built category.

Below you can see a couple of good looking Sonex'es, the shiny one in the middle is basically what we have in mind as far as looks goes.

Feel free to roam our web page, we will update our build section with pictures from the construction as we progress.

Should we decide to paint it bright yellow, this is what it will look like
This Sonex has its wing tips, cowling and wheel pants painted. The rest of the aircraft is polished to a mirror like finish. This is how we hope our Sonex will turn out
Simple and nicely organized cockpit. We might have something like this in mind

Hej Rune og tack for raskt svar!
Låter gott med er framfart og jag hoppas att under nästkommande år få sålt min Murphy Rebel 1650 så att Sonexorojektet får lite ekonomiskt bränsle.. ;)
Håper å få återkomma med litt spörsmål framöver om ok?
All the Best

Hello Folkens,
Hur går det med bygget?
Tror jag följer ert exempel för min Sonex och avstår från D-motorn....
Blue Skies!

Hei Ivan, det går fremover med prosjektet. Vi har hatt tre oppstarter med motoren og etter mye plunder med elektrisk og kjøling fungerer det nå bra.

Kommer seg Carl. Må si i fra når dere trenger klistermerker på flyet, så skal jeg fikse det for deg:) Kanskje en haikjeft også

Hi Guys, My Onex #117 flew for the first time today, no major issues!
How is the installation of your engine going?
Brgds, Dirk

Rune Bjørkelid 25.05.2018 19:25

Hello Dirk, and congratulation on your first flight, glad to hear it went well. Our project is moving along, all though not at high speed at the moment.

Dirk Verdonck | Svar 26.01.2018 11:03

Hi Guys, I'm interested in joining you for the installation course as I plan to use the UL350i in my next Waiex project. Dirk Belgium

Rune 27.01.2018 00:27

Hi Dirk, book your course directly with Evelyne at the ULPower HQ. Our date is February 16'th
Regards Rune

Hi, Can I have an e-mail address? Dirk

Dirk Verdonck | Svar 20.12.2017 15:59

Hi, I am a Belgian Onex builder and am about to finish my aircraft. The plan is after completing the Onex testing to start building a B-Waiex with UL350i. Dirk
