I got an X450 Carbon Fiber frame and installed all of my parts on to it to test with. It flew fairly well. I have made a video of the flight and it can be found here:

I have also assembled the plexiglass DJC1000-X4 'beta' frame and I flew it late tonight with some friends. I have a very poor quality video of the first lift off. After replacing a broken 'cross' motor mount adapter and tightening down a motor mount with no screw we got it to take off. It would start with tilting to the front right corner, but I got it off the ground. I have also discovered that I have absolutely no Yaw control at all. Full Yaw stick does nothing. I hear the motors speed up but they don't seem to do a thing.
I know that the frame is so bit that it will require PID tuning... and a lot of it. I have enabled more logging so that I can tune it correctly.
Several of the main frame parts on the plexiglass DJC1000-X4 'beta' frame we blocked by the wires from the HobbyKing Power Distribution Board. As a result some of the screws could no go in and the battery plate broke after several short attempts to fly getting no higher than about 5 feet off the ground. Having done no PID tuning and just throwing the frame together tonight I am very happy with the results.
Here are a few pictures from tonight for your enjoyment.
