Still fiddling with Gundam kits at the moment. I had recently bought the Strike Rouge and Skygrasper/Aile Striker set. A month or so later, I finally completed it in a state that I'd consider "partially acceptable". There's plenty of reviews about the kit, so I'll spare you the crappy assault of "build progress" photos and "poseability" photos demonstrating how the articulation works. This is the Vortex! Only useless information that no one wants will be shared here!
For the inquiring minds, the PG Strike (and presumably all other Perfect Grade kits) stand roughly 12" tall, which conveniently is the same scale as a 1:6 scale figure. Unfortunately, their hands are quite large and don't translate well to a 1:6 scale figure, and feel more like 1:5 scale hands in size. While off scale, this does provide an opportunity to all you PG Strike owners who want something more desirable in their arsenal than the included beam rifle, shield and shiny sword. What if you wanted to give your Strike Gundam something more... interesting?
Now, what about heavy weapons?
I tried out most of the bazookas/rocket launchers I had and found a lot of not-at-all surprising results. I took photos of the ones that worked best.
I couldn't get the FIM-92, FIM-43 or the SA-18 to work due to the wrists. If you wanted a Strike Stinger combo, it'll look awkward. Don't even bother with panzerfausts. Other models from the ZACCA collection simply didn't work due to the shoulder armor interfering.
There's one outlet left for 1:6 scale weapons: Melee!
It's convenient to know that a PG Strike can use about half of the possible 1:6 scale stuff on the market. The biggest problem is the wrists. I would recommend experimenting with other melee weapons than guns or rockets, as they offer the best results. Don't settle for energy blades when you can use a slab of metal to impale your foes.
