Handheld Flight Controller
Simple to Use
A device does not have to be complicated to use, even for a job as complex as controlling an unmanned aerial vehicle. With this idea in mind, the Draganflyer X4 handheld controller was designed to keep all the complicated flight functions out of the users way and let the computer do the hard work. Although the transmitter seems simple on the outside, it's actually a handheld flight computer interface, capable of telemetry feeds, camera control and many other functions.
Comfortable, Ergonomic Design
The Draganflyer X4 transmitter is designed to feel comfortable and useable in your hands. Made of rubber and high strength ABS, the transmitter is very sturdy and has enough weight to feel comfortable.
Real Time Telemetry and Flight Computer Display
What is the use of an advanced flight computer and stabilization software, if the user can't access its information easily? The Draganflyer X4 transmitter receives live, streaming video from the transmitter which can be viewed with the optional video glasses or on a separate video screen. We realize that most users fly the Draganflyer X4 outdoors, so we have included a powerful backlight, making the screen viewable in direct sunlight. Telemetry information available from the controller includes:
- System and Flight Time
- Attitude (Roll, Pitch, and Yaw Angles)
- Throttle Settings
- Battery Voltage
Audio and Visual Warning Screens
Because it receives all helicopter telemetry live, the Draganflyer X4 controller can warn you about low battery levels and many other situations that can affect flight. To assist in notifying the pilot to a warning with out the need to glance at the controller screen, each warning has its own distinctive tone. The transmitter lets you play all the warning tones, so that you can become familiar with them before flying. Knowing exactly the state of the helicopter, in real time, is one of the features that sets the Draganflyer X4 apart from comparable units.
Built In Dual Video Outputs
If you want on the fly monitoring from the video glasses, or to send video to another device, the transmitter does exactly what you need. A 5.8 GHz Dual Diversity receiver automatically selects the best video quality from two built in antennas and sends the best signal to the output jacks. Doing more than simply reading the signal strength from the antennas, the controller analyzes video frame by frame to determine the best quality signal.
Radio Interference? Not a Problem
The Draganflyer X4 transmitter automatically scans for and locks on to an interference free channel - eliminating the need for frequency control. Operating with 2.4 GHz, spread spectrum technology, the transmitter is not susceptible to random interference of any kind
Once you power on the Draganflyer X4 UAV, it automatically locks on and connects to exactly one transmitter. Even if other Draganflyer transmitters are operating in the vicinity of your flight area, you are guaranteed to be interference free.
Dragan Eye Pro Diversity Wireless Video Receiver
An embedded Dragan Eye Pro 5.8GHz dual diversity wireless video receiver incorporating two 5.8GHz video receivers is built into the controller. The Diversity unit intelligently switches between the two receivers in order to obtain the best signal. Switching decisions are not only based on RSSI (Receiver Signal Strength Indication), but also on VSQA (Video Signal Quality Analysis) which monitors video quality on a frame-by-frame basis. Dual antennas can be positioned to pick up the video signal from multiple angles. Dual outputs are located on the bottom of the handheld controller for connecting video goggles and a recording device.
Use Two Transmitters with One Helicopter
Two pilots, or one pilot and a camera operator, can control the X4 simultaneously. Able to connect wirelessly, the two transmitters communicate via a 2.4 GHz radio link. The transmitter's built-in computer allows you to determine which flight functions are controlled by each transmitter, so that you always have the control you want.
Using this feature, a student can practice controlling one channel at a time, gradually working their way up to full control. You can also have a pilot fly the helicopter, and a photographer control the camera. With each person free to focus on their particular jobs, you can obtain great looking aerial pictures and video easily. Whether you are training new pilots, or taking tricky aerial photographs that require special attention, the dual transmitter feature is extremely useful.
Video Glasses Plug Directly In
Frame your shot by seeing what the camera on the helicopter sees. A real-time video feed from the Draganflyer X4 helicopter provides a bird's eye view. The display screens in the video glasses only occupy a portion of your field of view, allowing you to keep the helicopter in sight while viewing the streaming video. This way a single user can both pilot the helicopter and also operate the onboard still camera or video camera.
