I have to large projects, one much bigger than the other.

My first project is the T-38 Talon, based on my modifications to mikoyanmaster's F-5. This is because the T-38 Talon is basically an F-5 with an extra seat.

The second project is the Desert Eagle in .50 AE. It will come with a to-scale .50 AE, .357 Magnum, and .44 Magnum cartridge, and be scaled to Cartridge Collection 1.

The third project is much, much more intensive. Following the success of Cartridge Collection 1, I have decided to do a second listing. However, while this listing will include new Soviet and German cartridges, it will also include previously introduced cartridges. Why? Because I want to make them to a scale of 3/2 SP units vs. standard inches, or 3/50.4 SP units vs. millimeters. Why this scaling in particular? While gun builds are often made to whatever scaling the user so desires, this scaling is closest to what is available. The previous cartridges were made to a more approximate scale, and now I want to make it closer to real scale.

Here's a helpful list of new and remastered cartridges.
