The Conquest X-30 is my premier attack/ fighter jet here. The 1986 Conquest was my first Conquest (fun fact, that goop around the "eyes" on there is where I spilled fake blood on it back in the day). This version of the X-30 that I have is from 1998. While I never did buy the original Python Patrol Conquest, I did buy the 2003 version when that came out.
My original X-30 is a vehicle I had since at least 1987, but when I made my draw down on vehicles I decided one X-30 should be sufficient, so the other two had to go. Nostalgia got kicked in the knee with my decision to keep the 1998 release, though. The 1998 has a great coloring, black missiles, and little improvements that made the canopy connection hinge much better, as well as some refining in the landing gear.
As much as I like a lot about the X-19, for me, my X-30 is small and fast enough to take on any air and ground opponents that may come up against it. I think with the X-19, it seems a little more "bomber" like. The cruise missiles in themselves could come from anywhere, that's a role the RPV could really fill in some aspects. Or even that imaginary attack sub just off shore that is able to assist the Joes on missions....
I think the little fighter, the X-30 is plenty good for my Joeverse. It has 4 missiles, 2 drop tanks for extended missions, but it still has that simple dogfighting aspect: guns! The twin nose guns are a detail that I've enjoyed, this bird is gonna get right up close to the action!
