Not another helicopter tutorial? Yes, yes, but this one is good and it’s short. Flying a helicopter in Bad Company 2 is damn hard and AdaptableFuton suggests changing the air controls to BC1 controls. Might make it easier but you probably lose manoeuvrability.
Also, and this is the important bit. Engineers can only repair the helicopter when it’s flying low. I didn’t know that. Must have been dumb luck when I was repairing that we were at the right altitude.
