Finally found a way to transport those stupid Raider craft...

So after having enough sails broken by in transit, I found a solution for the problem: Remember those foam inserts usually found inside foam army trays? Take those, and glue/tape four of them down onto a piece of cardboard. Set them in place in such a manner that the round flying base barely fits inbetween them, and the foam supports the corners of the Raiders. Bam, problem solved, no wiggle, no pressure on any of the spikes on the Raider. You can turn the whole assembly about 90 degrees and they'll still remain in place. Pictures coming soon...

My raiders dont fit in anything because i added blades to the side so i have to keep them in an open-topper box
