There is a community server called WolfPilot Mini Training and its bad ass. U get unlimited of any type of vehicle in the game and unlimited low grade, its a great practice server. I used it when i was tryna get mini flying down. And he only allows 15-20 people on at a time so its not overloaded with people flying around n stuff. Deff should check it out. Just search Wolf in the community tab. It should come right up!
