New Product

OSD PRO from Eagle Tree (RTH, AHI, Waypoints, Variometer, Voice, now shipping)

Got video?

Do you fly, drive or boat with FPV, or do aerial photography? We’re pleased to introduce the Eagle Tree OSD Pro.

The OSD Pro displays all the key information about your model’s status, and has many advanced features such as voice alerts, high resolution raster graphics, a new “RADAR” synthetic map, “Return to Home,” and waypoints within visual range.

Why should I choose the OSD Pro system???

There are lots of OSD choices out there. Here are a few reasons we believe the OSD Pro is your best option:

Buy with confidence: Eagle Tree is a full time R/C business since 2003, focusing solely on RC data products. It's all we do! Nearly all the other OSD companies are part time businesses or "one man shops" which may not be around when you need them.

Modularity: If we come out with a newer version of one of the OSD Pro components, you onlyneed to upgrade that component to have the latest and greatest system, rather than having to replace your entire OSD system when a new one comes along.

Easy setup: The OSD Pro is easy to configure exactly like you want it, with the included software. Click here to see the Configuration Overiew PDF. The built-in flight simulator makes it much easier to test your configurations before you fly.

Expandability: Eagle Tree offers myriad sensors that are fully compatible with the OSD Pro. Since we make these sensors ourselves, you're guaranteed that they will be plug and play, with no soldering, finger pointing, or headaches.

Powerful features: The OSD Pro offers advanced features, such as Voice Alerts, Programmable Alarms, "RADAR" synthetic map, "Return to Home", RSSI and multiple battery voltage displays, built-in Flight Simulator for setup testing,Artifical Horizon display, acoustic variometer, waypoints, full Data Logging with GoogleEarth and graphing with our powerful software.

World class support: we have full time, dedicated support staff, should you ever have a problem. We offer 24/7 support with our online RCG support forum, this thread, and our advanced web ticket system. Only the OSD Pro has built-in diagnostics which can be downloaded and sent to our support staff, so we can diagnose most issues easily without needing to return the product.

Easy upgradability:
We are constantly adding new features and enhancements to our firmware. These are just a download away. The OSD Pro's built-in USB connection makes it easy to update firmware with our powerful software. No need to buy a separate USB adapter, build any special cables, or other complex steps for update.

Part of a complete FPV system: The OSD Pro is complimented by our EagleEyes Ground Station, and will soon be enhanced with our EagleLink integrated RC/Video system. Other enhancements are in the works, that are fully compatible with the OSD Pro system.

Is it hard to set up?
While the OSD Pro has many advanced features not offered elsewhere, setup of basic features is quite simple. The quick setup guide, included with the OSD Pro, can be found here.

The OSD Pro system comes with built-in USB, and includes a USB cable, so no need to buy an adapter elsewhere to configure the device or update the firmware. In typical installations there is NO SOLDERING required. We also offer many additional plug and play sensors for the OSD Pro.

How it Works

The OSD Pro is a powerful, modular, fully configurable Video/Audio On-Screen Display (OSD) device, providing graphics, voice announcements, alarms, acoustic variometer with total energy compensation, Home Arrow, Return to Home, Failsafe, “RADAR”, waypoints, a flight simulator for testing, and many other features. The information displayed can be as simple or advanced as you like, depending on how you configure the display, and on which optional Eagle Tree sensors are connected.

The OSD Pro kit (pictured above) comes with our eLogger V3, and or 10Hz GPS V4, which includes a built in torroid ring and onboard filtering circuitry for cutting video Tx noise, which can greatly diminish reception with other GPSs that don't include this feature.

What Data Parameters can be Displayed on the OSD Pro?

All parameters available with our eLogger V3 and Data Recorders + optional sensors will be supported for display on the OSD Pro. Here are some examples:

* GPS Parameters (Distance to Home, Home Arrow, GPS Altitude, Ground Speed,Course, and more)
* Electrical Parameters (Pack Volts, Amperage, RX Volts, Servo Current, Milliamp-Hours, Watts)
* Performance Parameters (Airspeed, Barometric Altitude, Climbrate, Variometer,Temperatures, RPM, G-Force, EGT, Jet ECU Status, servo positions)
* Receiver Health (Dropped Frames, Antenna Fades, Missed Packets – requires Spektrum or JR FlightLog compatible Receiver)
* Call Sign, and many more

Tell me About the Advanced Features of the OSD Pro!

The OSD PRO advanced features include "RADAR," Voice Alerts, Return to Home,failsafe, and Waypoints.


The plane icon labeled “RADAR” above serves two purposes: the direction the icon is pointingindicates your present course. And, the location of the icon on the screen provides a synthetic map, similar to RADAR: the center of the screen marks the takeoff point, in a "bird's eye" view, and the plane icon moves around the screen indicating your model’s location. The maximum distance and the “up” direction is configurable.

Voice Alerts/Variometer

Imagine hearing the status of your model through earbuds connected to your goggles, or a speaker on your video receiver! The OSD Pro fully supports voice warnings and status updates, via the audio channel of your video transmitter. Most of the available parameters can be programmed to provide voice alerts. Either male or female voice can be selected.

For example, you can program the OSD Pro to periodically update you on altitude once a minute: “Altitude 3-9-1 Feet”. And, you can also program a low voltage warning “WARNING- Voltage 12-point-5 Volts”. Voice alerts can be combined with your camera’s microphone, so you do not lose motor or other flight sounds when there are no alerts.

Additionally, a varying tone Variometer with Total Energy Compensation (completelyconfigurable from the on-screen menus) is included. Any of our altimeters, or GPS altitude, will work with the variometer. But, the altimeters built into ourGlide and Pro recorders have very high resolution, which is required for the variometer to be useful in finding thermals. You'd use the recorder instead of our eLogger as the 'data collector' if you need thermal sniffing capability. The OSD-Pro will work with either one.

Return to Home and Failsafe

The Return To Home feature will attempt to bring your stable plane in a “holding pattern” above the takeoff point if radio signal is lost, by manipulating your model’s rudder/ailerons, elevator, and throttle, based on your settings. GPS and other sensor information is used to attempt to return the plane to home.

Unlike some other OSDs, the OSD Pro has standard inputs for the three servos required for RTH. You don't need any special adapter to use it.

Note that this feature requires configuration of several parameters via our on-screen menus. An on-screen Return to Home configuration wizard is built in to simplify this process. The feature may require “trial and error” testing, and may not work with all planes or under windy conditions. If you have a stabilization system, this process is greatly simplified. We plan on releasing additional sensors that will further simplify this feature.

A Failsafe feature is also included, if Return to Home is not desired, or you are not using GPS. The failsafe feature sets your aileron/rudder, throttle, and elevator to programmable positions, if radio signal is lost. This is most useful for radios without built-in failsafe.

The Return to Home and Failsafe features work with all known radio types.

Flight Simulator

A built-in flight simulator is included, letting you fly the RADAR icon around the screen, controlling altitude, throttle and turns with your RC Radio. Since the control surfaces of your model will move at the same time, this feature makes it easier to configure Return to Home and test your alarms and settings, and is also fun on rainy days!


Up to 3 waypoints (within visual range of the takeoff point) can be programmed into the OSD Pro, for aerial photography or just for fun. The locations of the waypoints are displayed on the RADAR display, making it easy for you to manually fly to the waypoints (the system will not autonomously fly to the waypoints).

How Do I Configure and Control the OSD Pro?

The OSD Pro's built in on-screen menus and Eagle Tree’s drag and drop configuration software makes it easy to configure the OSD Pro to display what you want to see, when and where you want to see it. As few or as many parameters as you need can be displayed.

Our software lets you configure the OSD with up to 20 data parameters per screen. Also, the same parameter can be displayed on multiple screens.

The OSD Pro's on-screen menus let you set up the Return to Home feature, set audio volume, configure GPS settings, turn on and off the graphical features, and much more, without needing a computer at the field.

Two servo channels (one of which must be dedicated full time to the OSD Pro) let you switch between on-screen menus to further configue the OSD, or turn off the OSD entirely.

How Do I Hook it Up?

The OSD Pro Expander has the following connections:

* Connection to the eLogger or Data Recorder
* Servo-style connections to your camera’s “video out” port and your videotransmitter’s “video-in” port
* Servo-style connections to your audio microphone (if you have one) and to your video transmitter's audio in port.
* Servo connections for controlling the OSD from your radio, and for Return to Home and Failsafe features. The servo connections are Aileron/Rudder In and Out, Elevator In and Out, Throttle In and Out, Aux 1 In, and Aux 2 In. Note that the Aux 1 channel must be dedicated to the OSD Pro, but the Aux 2 channel may be shared with other functions on your model.
* Five male to male Servo extension cables are included for hooking up to your servos.

Is the Eagle Tree OSD Pro System “Future Proof”?

Yes! Eagle Tree has been in the R/C Data business for many years – it’s all we do! We won’t lose interest in your data equipment shortly after you buy our product, and we have full time support staff to help with any issues you encounter.

Also, our systems are fully modular. If we come out with a new sensor, a more powerful OSD Expander, a software improvement, etc., it’s easy and cost effective to update the system. So, your system is not obsolete a few months after your buy it.

And of course, the OSD Expander’s firmware is updatable from the internet, making it easy for you get support for new sensors, access to new features, and download the inevitable bug fixes.

But I also need Data Logging!

Complete data logging of most parameters is included. The data are downloaded via the included USB connection, and graphed and analyzed with our powerful Windows software.

wow this sounds perfect!

two questions:

1. is switching between kilometers/miles possible?
2. are there any audio or video examples yet? especially for the varying tone Variometer?

Thanks for the kind words!

Solars: Yes, switching between Metric and English is fully supported. Audio and video examples will be coming soon. The varying tone variometer will sound the same as our Seagull Glide variometer (varying pitch to indicate degree of lift/sink, and broken tone vs solid tone indicating direction). Many aspects of the vario are tunable.

There's another thread going about how the people have problems with the number of satellites dropping when using the EB-85A with a 900Mhz video TX. Have you seen this? Apparently, having a SAW filter on the GPS will help this. Is this something you have considered with the new OSD?

Hi tychoc,

Our GPS Expander is in wide use for a long time with our 900 MHz Seagull telemetry, operating at up to 1 Watt, without reported issues. But, we will certainly monitor and address the issue if problems are reported with our equipment!

Should I cancel a preorder with one of the competitors and wait for this one to be ready?

Hi Carlyle,

If this question is directed to me, I certainly can't give an unbiased answer, but here goes:

Personally, I usually buy things that are available now, if I need them now and they do what I need. I'm even more inclined to buy something now if I have the opportunity of upgrading it later. There are a few OSDs available now (ours is one), and I've lost count of the ones announced for later. Since our system is modular, we are offering a $20 upgrade that lets you have OSD now, and OSD on steroids later.

Our hope is that by doing this we will make the decision easy, but I definitely want to hear if we are off base!

Bill, if I understand right, the RADAR feature shows a circle with line representing the location of home relative to the aircraft which is represented by the center of the screen. What does the line extending from the circle represent?

Do I understand correctly that if home is in front of the aircraft then the circle will be on the top of the screen, and if home is behind the aircraft the circle will be on the bottom of the screen etc?

Hi Bushman,

With RADAR, the center of the screen marks the takeoff point, in a "bird's eye" view. The location of the small circle, relative to the center of the screen, indicates where you are on a map, relative to home, north up, bird's eye view.

The line on the small circle is the home arrow. If you need to turn right 20 degrees to get to home (based on your present course) the line will point to 20 degrees.

The only reason for combining the home arrow with the RADAR circle was because that's similar to what F-16's do. :-) Of course, we can separate the home arrow from the Home RADAR feature, and perhaps we should. We could make the home arrow a separate gauge at the bottom of the screen, or a line orbiting the center.

Hi PG,

You bet! In fact, the complete OSD system includes the eLogger V3 has the data collection "brains." Note that the eLogger V1/V2 will also work, but those did not support GPS.
