Welcome to the club.
Theres NatComAir, Mahou, Abel, Herven, YSBRA, etc.
click here to go to the civilian forums and read up on all the vas
As for which addons.... DOWNLOAD THEM ALL!
JK, unless you want to
It all depends on what you want to fly and your level of desired detail. For Example want some low detail airliners that wont strain your computer check out Daves and Dans simple airliners. Want some wicked high detail graphics card melting aircraft check out decaffs boeing models, takaty's aircraft packs, najmi's a380 just to name a few
What addons you decide to download also depend on if you want to fly online or not. I fyou want to fly online try to download ALL the aircraft on that server, just to avoid any errors or block planes. For example if you want to fly on the YS Civil aviation server youll need to download whats on this page
https://sites.google.com/site/civavserv ... craft-2017
As for maps again just download what you want to fly or if you want to fly online youll need to source the maps. For example if you want to fly on the civilian server click the "i" next to the server name on the side bar to you left and on that page youll see the scenery/map name. Simply copy and paste into the forum search bar to find it.
Well hope you enjoy your stay well see you soon on the servers!
