Starting with the cockpit. The only change here is a pretty minor one. The cockpit cover latch is different. Really it's almost insignificant. I dont know why they made it like that.
The neck connection is a bit different.
Most of the changes can be seen in this shot. Chest frame cover, cockpit hatch cover and the torso/shoulder joint are all different from the Strike.
This is the last part. The elbow armour connection panels are different. Outside of the parts I mentioned here, there are no extra parts that are necessary for the Astray frame.
As you know all know now, I've used the PG Astray Red frame for my Strike Vermillion and I will be using the Strike frame for my PG Astray. Here they are side by side before armour application. I really like the Strikes lower legs and feet. The Astray feet seem really bulky to me now.
That's all for now. I'm a bit behind on posts so I suspect that I'll be blogging a bit more within the next couple of days. I have a free weekend with no plans so that means I can finally concentrate on the things that matter. *looks at his Red Frame box*
