Am currently involved with several projects, RV9A quickbuild, RV4 slow build, RV6 just acquired with some parts already built but needing re-doing in certain areas. The quickbuild is probably going to be finished first and should be diesel too.
I have only worked on the 9 so far, but the building is great fun, educational, and comes recommended!
The quickbuild also seems a great way to go about the build as most of the really time consuming/mucky stuff is done as far as I can tell, and it's just like Christmas when the fuse, wings and bits and bobs arrive, although lifting them off our trailer was interesting to say the least!
Have no experience with Europas yet, but haven't heard any bad things about Vans at all, and can't wait to fly the aeroplanes!
If you want to know anything specific e-mail me and I can hopefully find out for you.
Regards,
MS
