In 2009 I was lucky enough to get to paint up the 5th edition IG black box. The new Cadian command squad and Valkyrie were the contents. It was a trick to assesmble the Valkyrie since there were no instructions with the box... total bummer, there was no flying stand either.
This was one of the most complex models GW had released at this point, and a lot of fun to build and paint. The interior and cockpit are really well detailed, even though I opted to leave out the door gunners.
The plastic Valkyrie was one of the most anticipated kits ever after the plastic droppod when it was released. I really had to work to get my paint job to pop on this one since the model would be on display. I used the following recipe:
Prime with Armoury Black PrimerShadow GreyCodex Grey drybrushBadab Black washSpace Wolves Grey drybrush
The metallics are as follows:
Prime with Armoury Black PrimerBoltgun Metalcustom mixed black ink washBoltgun Metal drybrushChainmail drybrush (very light)
This is the same recipe I use to this day, just with the current versions of the GW paint. I also tend to use Rustoleum spray cans to prime everything.
