Well, I've had a GP Lancair sitting in my living room still in the box for over a month now. Now that it's available in the sim, I'll have to build it to see how it compares.
What do you mean they don't have 3D planes? Isn't an Edge or a Cap considered a 3D plane?
I guess you can put down the Osprey as another gimmick plane. That and the Harrier would be way cool to see as an RC model, but it would be next to impossible to design all that roation stuff in a small model and have it be reliable enough to fly more than once. Can you image how much one of those would cost?
