After getting so many replies before. I want to keep you up to date.
Back from OSH I'm as far as before concerning my decision.
At first, I've spent a lot of time browsing through the homebuilt area and the guys of VANS have been very friendly and show a lot of patience.
I was lucky to get a demo flight in the 7 and it was - of course - great. To remember, I was pretty sure to decide between 12 and 9, but after flying the 7 and sitting in the 14 I was completely lost
I loved the space and the look of the 14, the efficiency and comfortable cockpit of the 12 with a great visibility, the performance of the 7 with 200hp. I have read so many times about "Defining the mission" and there is nothing more difficult than this. On the one hand, there are the things you do right know and on the other which you'd like to do. I was a little disappointed about the visibility and seating position in the 7+9. There is a big difference compared to the newer models.
I was pretty sure to return home and be sure which airplane to build after having seen all the kits in real life...
But it was nevertheless a great trip!
