Thanks, that one does look similar as to the one in the photo. Found a couple others but was slightly different though. Have bookmarked the site, might buy instructions from him later, he only asking for 5 Euro for them, although adding that donation is welcome.

And in regards to being 5k pcs, that be ok. Falcon is 5174 parts and thinking of maybe building that one as well one day.
