I've converted up some Dark Eldar Reaver Jetbikes as part of the concept. My corsairs are built using a mix of Dark Eldar and Eldar bits anyway, so the bikes make a good mix of parts along with some pieces that I've created myself.
They are designed to look close to the Eldar Jetbike Prototype that was shown off years ago, although I've done some modifications to the design. If you remember correctly, the Eldar Jetbikes of both the Craftworld and Dark variety are supposed to share a common design.
