Just as the title says. I tried many times to do ANYTHING in Reaver, Scythe or Mosquito, but I think their defualt setup is crap. It's theoretically not pay 2 win, but come on - without spending like 3000 certs on single air vehicle it's just flying free frag. Fuel tank is a joke and default air setup is only barely capable of intercepting enemy aircraft. And by intercepting I mean "to keep them busy for a while until they destroy you with more capable weapons and upgraded manouvering". For example Lightnings and MBTs are pretty usable with their defualt setup. Of course they are far worse than ones with upgraded armor, fully upgraded cannons and other stuff, but they are able to provide real armored support. Default fighters can provide some touristic flying for fun, but I don't believe they have any combat usage while EVERY flying thing is nowadays certed up to the roof.
