I never had the AD design kit in hands so I can't answer, All I could say is that in my part of the world znline is known to deliver top quality and give excellent support. On the fouga, A lot of optional extra work can be factory done. flight controls hinging, gear doors installation and son on.
check znline.com for the list of available options.
About the website I have to admit that the aircraft description is much more clear in french than in english.....
I'll talk to JP about that when back from holidays
