"not worth it to resell, but 25k inc engine in the air...the engines are a 2.1lt vw i think they are around 7k new, ive seen some youtubes of them doing aerobatics and they look pretty solid, are there any owners here?"
Hey Acro, there is a pretty active Sonex group here : http://sonexaus.wikispaces.com
There are around 106 plans/kits sold to Australia, and 28 flying examples of Sonex,Waiex, Xenos and Onex. according to Sonex Aircraft LLC official figures.
2 Sonex including my own, and 1 Waiex are just about ready for first flights... probably a few more waiting in the wings.
The figures you quote above would be in the US, you would have to factor in import costs to get engine and kit here. They are quite cheap in the resale market, not sure why as they are great bang for buck. A tri-gear aerovee has just been listed on the RAAus members market for $30k. If I had just started building mine, I probably would have dropped everything and bought it.
We have a handful of VH registered examples as well, no problems doing basic aerobatics.
I imported my kit 8 years ago, so wont quote you costs as the exchange rate was bloomin' poor!
