While designing the Dark Eldar Reaver Jetbike, they simultaneously designed the craftworld jetbike which was apparently flagged for a new model in the future. When GW shows such thought put into our products, they really do make long time 40k players very excited. Here is what they said about designing Reavers and of course some pics.
Jes: The Reavers are perhaps the best example of the similarities and differences between Craftworld and Dark Eldar design. The Craftworld jetbike design was looking dated and had been earmarked for a future remake, so it made sense to work on the designs simultaneously. Although the basic layout of the chassis, the carapace, the rider position, the fins and the weapon pod would stay constant, the styling had to reflect the divergence of the two factions from a common root. A common chassis with maquette rider was produced as the first stage.
Two prototypes were sculpted onto the basic chassis: one Craftworld and one Dark, shown here. Where the Craftworld bike would feature lots of aerodynamic cowling and a uniform look, the Dark Eldar version needed to look more stripped back and 'sharper'. Fins that were blades reflected the fact that the bike itself was the weapon; pierced carapaces used negative space to change the silhouette; concave rather than convex surfaces linked the bike design to the Raider hull. The small pop-up targeter on the top of the carapace was added at this stage, even though it started as a pencilled-on panel line.
More concept work followed, variant fins, intakes and carapaces were worked up. The Reaver bike had to be customisable to reflect the individual riders. The carapaces themselves were the most dominant part of the design, so they varied the most; we imagined that the different piercings would give each bike a different sound as they swept past the arena faithful, each rider having a sonic 'signature'
