After spending quite a while building a pixhawk based Multiplex Cularis with FPV, and lots of foam cutting to fit everything (including 3 cameras), here is the result:

Fitting all the APM and FPV gear in there is kind of tight, but it's doable.

Specs:

• 80Amp Castle Phoenix ESC
• Neumotor 1905 2.5Y 600-1200W motor 865kV (too heavy and powerful but I inherited it with my old Cularis)
• 4S 3300mAh lipo
• 14x8 folding prop, 60A, 960W power at full power takeoff (same power with 12x8 prop)
• 5V BEC to power servos and backup power to pixhawk
• Pixhawk with ardupilot 3.2.3
• 433Mhz telemetry radio
• MinimOSD with minimosd-extra R800
• 12V uBEC for Vtx
• 900Mhz 500mW video TX with 5V output used to power 2 mobius cameras and FPV camera
• Narrow angle Mobius for forward bottom view
• Wide angle Mobius for rear bottom view
• Fatshark TVL 600 FPV cam on top
• RC controlled onboard video switcher for the 3 analog video sources
• Lost model finder plugged into an RC channel
• Separate loud Keyringer with independent battery, sound activated

Total weight is a bit heavy, around 2.1kg, but with the huge wings, it's not a big problem. The wing area is 55dm^2, and wing loading of about 40g per dm^2 (the pure glider version is only 25g per dm^2).
