    Tromso Red Cross Multitask SAR hexacopter

    Here are some pictures of a SAR multitask hexa-copter for search and rescue operations, that I built for the Norwegian Red Cross in Tromso.

    It is based on a Tarot T960 hexa-copter frame and has removable/swapable payload for different scenarios through a custom built quick release system (camera-rig, light-rig, drop-rig etc). The camera rig is to be a independent operated 3-axis brushless gimbal with a Flir TAU2 IR sensor, a zoom SD camera and a Mobius HD camera.

    There are a lot of custom built parts on the machine. All the red parts are 3d printed from strong ABS and the lower bottom plate and the fixings for the low-slung batteries and the payload module are cnc milled from cfk or gfk.

    You can find a lot more pictures and a build diary in this link (from page 2 to 7). Please use a online translator to translate from Norwegian to your preferred language.

    It is now ready for flight testing and hopefully we will have it certified for RPAS use early next year

    look interesting, what's the flight time?
    "RSSI on the OSD? No, it just make me nervous..."

    Correction: No more nervous with TBS Crossfire! :p

    Regarding flight time. This will be mission and payload dependable. This hexa-copter is not built as a long endurance machine; more for multitask use. With the current batteries I guess it might be in the 15 min range. Lighter multi-copters with extended endurance (only camera package) are on the planing stage. Same goes for fixed wing platforms with extended endurance.

    Here are some details about the hexa-copter above:

    Tarot T960 hexacopter frame, with landing gear and OD payload module
    Dualsky 5015 320kv motors
    40A esc
    18x5,5 prop

    2x 5800mAh 6S Lipo Pack

    Taranis rc control
    Frsky L9R rc rx

    5.8gHz VTX
    CP SpiroNet Antenna V2
    600TVL FPV tilt Camera
    3 Way RC Video Switch

    Bec 12v – DC-DC Boost-Buck regulator 5-30V
    2x 5v bec
    High Density Waterproof LED Flexible Strips
    Nav-light/strobe set (led)
    RX Controlled Switch
    + OD cabling, electronics and parts

    Payload module options:
    - Camera package: IR + Zoom + HD cameras
    - Light rig for illuminating objects on ground and/or for location/directional aid
    - Drop module
    - etc
