The abbreviation UAVP stands for "Universal Aerial Video Project". It is a flying object, ideally suited for making aerial videos and photos (aerial photography), but is also a lot of fun to fly whether indoors or outdoors. The UAVP-NG Hardware 0.22 consists of two PCBs, the flight-controller board (FC) and the sensor board (SB). Both contain a peripherial CPU called RC-Controller (RCC) and SB-Controller (SBC). ProcerusUAV - http://www.procerusuav.com This is serious equipment used primarily for military spec applications - procerus will build RTF systems using thier high quality electronics for certified applications...such as the service sector and search and rescue operations. With advanced features, this electronics package from Procerus is second to none on the market. Caution: always test your electronics setup for first time powerup with the propellers removed. Batteries LiPo (Lithium Polymer) are the best choice for now and inroads have been made in battery technology over the last years with greater output and performance continually being offered across the board. 3 cell 11.1 volt or 4 cell 14.4 volt 2600 mAp to 6000 mAp. Prices range from $30 on www.hobbycity.com to over $200 + for more expensive batteries. A LiPo battery charger is needed to recharge the batteries and these can also be bought from most on-line RC stores - you might want to consider a multi-port charger for charging up to 4 battery packs at once. The AD-8 and ADX-4 configuration uses larger amounts of current for flight and higher discharge rates are recommended. 4 cell 14.4 volt power offers increased performance and endurance than a 3 cell 11.1 volt power system. Batteries with a discharge rate of 45C and higher are recommended. New LiPo batteries currently emerging on the market are claiming peak discharge rates of 90+C; note, higher "C" rated batteries are recommended. Recommended battery is Hyperion G3 EX series: LGG345-3300 to -LG345-5000-4S Budget battery worth considering is the Turnigy 4S Nano-Tech 3300 - 6000 mAp. The battery tray on Droidworx airframes are universal and designed to accept most battery sizes and shapes. Note: the SkyJib series craft with larger 2826 or 4120 series Axi engines or 15 series Plettenbergs engines will require 5 or 6 cell LiPo batteries. Caution - LiPo Batteries are dangerous if handled incorrectly - please view the Lipo Care page below: LiPo care information Radio Gear Futaba, Spectrum, Graupner 2.4Ghz. Hoverfly use and recommend Spektrum radio gear for their flight control. The Mikrokopter platform is designed to accept the signal stream from these radio systems through special adaptations in the Mikrokopter electronics; Spectrum via a satellite only installation, Futaba through a special PPM receiver and the Graupner via Jeti Duplex. Up to 12 channels are accepted by the MK platform and 9 channel radio systems are recommended to allow for all possible functions. 7 channels are required for the crafts controls, 4 for throttle, yaw, pitch and roll, 1 for height hold, 1 for GPS position lock and return to home feature, 1 for "care free" flight mode leaving two for camera functions or other accessories. Recommended systems are Graupner MX16/MX22 + Jeti telemetry, Spectrum DX7/8/10 + satellite and Futaba 9c/10c/FX30 Camera’s Note: higher voltsge recom regulators are advised for use with photohigher mounts to provide 6.5 volts from the FC be careful to read the data sheet before fitting this to your FC to ensure the correct connections are made. Recommended hobby camera - GoPro Hero HD and HD 2 - ContourHD - Drift http://gopro.com/ http://contour.com/products/contour-plus http://driftinnovation.com/hd170-action-camera/ Note these Camera's are perfect for the new Droidworx CX series craft. The droidworx-photohigher pro series gymbal and extended landing gear option will accommodate larger DSLR camera's and HD video camera's. This is a pro-setup for smooth gyro stabilized operation in roll and tilt axis offering superb results. The smaller av130 pro-mini is also available for sub 500 gram camera's. 360 versions of these are also available. A smaller lighter AV100 tilt only mount for point and shoots also from Photohigher. The MD2-DW from Mark Dana is also a lightweight option for smaller compacts and GoPro. Shutter Control Shutter control for camera's (still photos) can be accomplished by installing a remote infra red device. These can be sourced from www.blip.com.au in Australia. A list of suitable camera's for these devices can also be found on that site. Alternatively the camera can be set to shoot every 5 seconds or a manual remote servo can be fitted to fire the shutter at will from ground equipment. FPV - video downlink and telemetry - (First Person View) As the recommended radio frequency is 2.4Ghz for your aerial droid your FPV system cannot conflict with this bandwidth. 1.2Ghz or 5.8 Ghz systems are therefore recommended for video transmission (900 Mhz is a banned frequency range for public use in some countries). The recommended telemetry downlink connections are Jeti and XBee. Please note that placement of the XBee module on the craft is critical - it must be well away from the flight controller and speed controllers. Note: FPV piloting is against the law in some countries including Australia and the UK: be sure to check with the relevant civil aviation safety authority in your country or ask on the international forums before buying, installing and operating an FPV system. FPV telemetry equipment allows the possibility to see through the lens of the onboard camera equipment for an aerial view for framing shots and video footage and also just for the unique experience of that perspective. It is strongly recommended that professional aerial applications always use a two person operation with the pilot of the vehicle solely focused on the craft whilst the second person operates the camera via wireless telemetry. Sources for FPV equipment are: www.globe-flight.com www.rangevideo.com http://www.firstpersonview.co.uk/ http://fpvpilot.com/default.aspx. A good guide for FPV safety can be found at: www.fpvpilot.com/safe.aspx Safety - See also "FLT-OPS" button on the front page of this site. FLT-OPS = Flight Operations You are in control of a potentially dangerous craft – be responsible in your actions and choices when operating this craft. Always check your equipment before you fly; a simple preflight check to ensure that everything on the craft is in the right place and all equipment is functioning normally. Safety precautions to take are: Battery levels on the craft and transmitter are fully charged. Propellers fastened tight Engine mounts tight You have the correct model selected on your transmitter The area is clear and everyone nearby is notified of your intent to fly. Choose a level area for take off. Keep others clear in front and behind. Plan your flight and survey the flight path for wires and obstructions. Set the timer on the transmitter to 80% of the known battery duration. Always keep the craft in line of sight of the transmitter – never fly behind trees etc. Fly well clear of other people and their property - 30+ meters. Regulation The Civil Aviation Safety Authority (CASA) in Australia allows the use of these vehicles for recreational and non commercial purposes . However you must adhere to operational regulations at all times. The maximum height or operational ceiling for these craft is 400 feet – everywhere. You must not fly above this height. You must also never fly near an operational aerodrome or airfield at any height and you are responsible for the safety of others who are in proximity of this vehicle whilst it is on the ground with engines on and in flight. You may use this vehicle for professional aerial photography and video work in Australia only after completing an accreditation course with CASA. Check with the relevant aviation authority in your country before operating a commercial aerial photography and video business. Please check safety and operational regulations in your country before operating and piloting this craft. Forums Be sure to make use of forums for help in setting up your aerial droid.
