From the release:
Each Raven-Class Medium Attack VTOL comes with a hollow interior to allow for multiple modeling options (including a closed or open ramp that can be positioned without gluing to allow for multiple options) along with several type of weapons including miniguns, Anti-Tank missiles and rocket pods. It also includes the option to attach landing gear.
The Sparrowhawk-Class Light Attack VTOL comes with separate engine nacelles and “benches” on each side to allow for troops to ride quickly into battle. Under the nose is a twin-linked high-velocity laser cannon.
