Controller platform for Diatone FPV250 style quadcopter frames

Everyone loves these inexpensive little quadcopter frames. I have the basic frame without the fpv cage arrangement on it. I wanted to strap the battery to the bottom, so needed a place for the power distribution board. This little build allows you to put the PDB under the controller in the central well area of this frame. Then you can mount your controller on top for easy access. The pictures tell the whole story.
The platform is 11mm high, so should be flush or slightly higher than the top of the frame... that should provide enough room unless you want to jam more stuff underneath, or have sloppy wiring like I usually do.
I haven't really figured out a good way to keep the thing intact in the well area yet, so I'm just taping it for now. Will hopefully work out something better.
There are ample slots for wires to come out to all the important parts of your quad.
