Sorry that you've decided to move on from your original squad, but rest assured, you're more than welcome here if you decide to stay.
As you might have gathered, things around here are fairly...well...'informal' to say the least.
In game our realism settings are pretty relaxed although it is preferred if you don't use the minimap radar to call out targets BVR. Most of us fly either icons off or really short but for navigation purposes the majority have the plane on the map - no-one's that keen on getting lost deep in enemy territory. We do though have complex engine management on so you'll need your throttle, pitch, mixture and radiators set up for the planes that require it.
Our dedicated GBS nights are Sunday and Tuesday evenings starting around 8:00pm for 2-3 hours or until people get bored. This Sunday though is a campaign session but if you've done some P-38 flying you could definitely join in with that if you wanted to. In addition, the Dogz GBS dogfight server is up 24/7 (mostly) and a quick note in the chatbox will often find people willing to fly. I'll PM you our teamspeak server details so you can join in the chat too. If you're also into flying DCS, then Mondays and Thursdays are the dedicated nights for that.
As the guys have mentioned, there's no barrier to entry and the only requirements are to get involved and have fun.
Cheers
Jabo
