T4 quad upper componet plates

I decided to go with a Brain flight controller setup on my T4. I redesigned the top plate to have some captured nuts that can be screwed into from the top once the top plate is installed. I added a separate isolated mounting plate for the camera. I was having major stability issues with too much mass on the flight controller isolated plate. I will have to post the flight controller plate later once I recreate it(my file got corrupted). I use 100g iso balls between the plate and 3m X 5 screws and
