Ok, so I just got myself a new 450 size heli case from Hobbypartz, and I gotta say I really like it. Its not really an aluminum case but it looks cool and will do a great job protecting you 450 size (and smaller) helis while to tranport them. I need to get myself 2 more now. When you buy the case, you have to remove the foam inserts you plan on using, which I like atot because you can use the left over foam for additional padding.
