The Graupner Fat Shark Attitude V2 CE goggles (No. 48325) are a versatile and portable device designed for First Person View (FPV) applications, offering an immersive experience for experienced modelers. These goggles are primarily intended to reproduce audio/video signals transmitted from a 5.8 GHz FPV camera or directly connected from an external audio/video source, such as a DVD player.
Function Description
At its core, the Fat Shark Attitude V2 FPV goggles provide a visual and auditory interface for remote-controlled models, allowing users to experience flight or operation from the perspective of the model itself. The integrated wireless NexWaveRF 5G8 receiver module ensures reliable reception of video signals, while the Trinity (3-axis Pan/Tilt/Roll) Headtracking technology enhances the immersive experience by allowing the user to control camera movement simply by moving their head. This head-tracking feature translates head movements into corresponding camera adjustments on the model, creating a more natural and engaging control scheme.
The goggles are equipped with a display system that supports both NTSC and PAL auto-select (interlaced) formats, featuring two full-color micro VGA LCDs with a resolution of 640 x 480 dots, totaling 922k pixels. This ensures a clear and detailed image for FPV flying. Audio capabilities are also integrated, providing stereo sound to complement the visual experience.
Powering the device is a 1000 mAh, 7.4 V LiPo battery (2S1P), which is rechargeable using standard RC battery chargers. The goggles also offer an AV in/out port, allowing for connection to external video sources or recording devices, expanding their utility beyond live FPV feeds.
Usage Features
The Fat Shark Attitude V2 CE goggles are designed with user-friendly controls for an optimal FPV experience. On the headset, a channel select/headtracker reset switch allows users to cycle through available 5.8 GHz channels (CH1: 5740 MHz to CH7: 5860 MHz) and to reset or access the headtracker menu. Audio beeps provide feedback on channel changes, with a long beep indicating the top or bottom limits of the channel range. A vertical press on this switch activates the headtracker menu/reset function.
Display control is managed by a separate switch, enabling adjustments to contrast (left/right rocking) and brightness (forward/back rocking) to suit varying lighting conditions and personal preferences. An RX power switch is also present, allowing users to turn off the receiver module to prevent video conflicts when an external video source is connected via the AV cable.
The headtracker, a key feature, initiates in pause mode and requires the reset button to be depressed and held to begin camera motion. The headtracker menu offers extensive customization, including servo center point adjustment, pan and tilt ratio settings, auto-pause on/off for movements exceeding 90 degrees, motion limits, and cycle time adjustments. Users can also restore factory defaults if needed.
For external connectivity, the goggles include a PS/2 data port for the headtracker, an IPD (Interpupillary Distance) adjustment mechanism to ensure comfortable viewing for different users, and an earphone jack for private audio. The AV in/out port, using a 3.5mm jack, facilitates connection to external devices for video recording or displaying external video sources. It's crucial to use the included AV cable to ensure proper pin connections.
The goggles are compatible with Fat Shark or ImmersionRC transmitters, and users are advised to select a channel with minimal interference for the best performance. A range test is always recommended before flying to ensure both AV and RC controls are functioning optimally. Proper antenna placement (vertical orientation in an open area) is also emphasized to maximize signal strength and avoid multipathing issues.
Maintenance Features
The Fat Shark Attitude V2 CE goggles are designed for minimal maintenance, but certain practices are recommended to ensure longevity and optimal performance.
Battery Care: The 1000 mAh, 7.4 V LiPo battery requires careful handling. It should never be left unattended during charging and should always be charged on a non-flammable surface in a room with a smoke detector. Users must continuously monitor the battery and charger throughout the process and keep a suitable "Class type D" extinguisher nearby. Charging should not exceed a 1C rate, and chargers that do not detect the full charge state should be avoided. Any signs of overheating or inflation indicate a problem, and the battery should be disconnected, moved to a fire-safe place, and disposed of properly. If the battery becomes fully discharged or shorted, an internal safety circuit may trip, requiring a 9V tap to the barrel connector for reset.
General Care: The product itself does not require special maintenance. It is important to protect the goggles from dust, dirt, and humidity. Cleaning should be done with a dry cloth, avoiding detergents, and rubbing lightly.
Optics Care: The goggles' lenses should never be exposed to direct sunlight, as this can cause magnified sunlight to burn off the LCD color filter, resulting in white dots on the display. For users with near-sightedness, optional diopter lens inserts (-2, -4, -6 dpt) are available and can be inserted after peeling off the rubber eye cups.
Troubleshooting: The manual provides a comprehensive troubleshooting guide for common issues such as no image, interference lines, and headtracker malfunctions. This guide helps users diagnose problems and offers solutions, from checking power connections and channel selection to ensuring correct antenna usage and proper setup of RC radio settings. If problems persist, users are advised to contact the Graupner Service Centre.
Environmental Protection: The product and its battery should be disposed of at appropriate collection points for recycling electrical and electronic equipment, contributing to environmental protection.
By adhering to these usage and maintenance guidelines, users can ensure a safe, enjoyable, and long-lasting experience with their Graupner Fat Shark Attitude V2 CE goggles.
