In case this is helpful to someone, my build log:
http://marc.merlins.org/perso/rc/post_2015-04-23_FPV-with-Multiplex-Cularis_-v2.html
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).
