I've always looked at the Forgeworld Raven and though I could probably make that out of a Raider body, just change the wings because I didn't like the look of them. The problem was it would cost a Raider body, which I didn't have any extras of. I had always kept a look out for spares on the cheap, but never saw any. But with the new codex and new models the old ones, which were pretty beat up, went into a closet. I pulled a couple out recently, and took the most battered one to be re-built, better, faster, more in line with the new styles. Early on I decided to make the wings resemble the swept back Skyboard wings. Then design the body to have a Jetbike look.
With some leftover 1/8" plastic sheeting from a recent bathroom reno I started by cutting them out with the jigsaw, then smoothing them down and shaping them with the sander. The Raider got the platforms and driver wings clipped off and the front was chopped about where the scoop underneath began. From there the wings were added, and a front nose piece added. At this point I need to add some thin cardstock or plasticard to add some flow to the tops and bottom of the model and fill out the front cowl, but it's definitely taking the shape I want.
The plan is to use it as a Raven in the end, with the splintercannon underslung. But I may hold off adding that and use it as a Voidraven bomber until an actual model is released.
Once it's a little further along with some better contrast pictures I'll post more shots.
