Guardian 2D/3D Inertial Stabilizer (Stand Alone)

Price $74.99


Q: Why do I need the Guardian?, The Guardian helps both beginner and expert pilots fly with confidence, and provides two key modes of operation:, In 2D flight mode, Q: Will the Guardian work with my model?, Q: I Fly FPV. Is the Guardian for me?, Q: How do I install the Guardian?, Q: How do I configure the Guardian?, Q: How does the Guardian work?, Q: What sets the Guardian apart from other Stabilization systems out there?, Q: I want one for each of my planes! When and where can I buy it??, Q: Where can I find more details?, Q: You are missing the feature I want! How do I tell you what you need to add?, * Note: a standard "micro" USB cable, used commonly with mobile phones and eBooks, is not included but is required for PC configuration and firmware update. You probably already have one, but if not, you can purchase it from us or elsewhere.,


Based on Eagle Tree's proven inertial stabilization technology, the Guardian 2D/3D Stabilizer is a
revolutionary, must-have product for your plane.

Whether you fly gas or electric models, wings, foamies, sailplanes, or just about any other fixed wing model, the Guardian is for you!

To stabilize your model, just mount the Guardian in a level orientation, do some minimal setup, and away you go. No additional equipment is required for stabilization.

At only $74.99 (USD, MSRP) the Guardian provides some great protection for your investment, while making it more fun to fly and easier to perform advanced maneuvers!

, the Guardian provides much smoother flight and wing leveling stabilization for your model, which makes it a lot easier to adjust and fly your plane. The Guardian "remembers" level flight for your model and returns it to level flight when needed, as well as providing precise "fly by wire" control. You may think that your model is on rails! The Guardian is also great for FPV flying.

If you are a beginner pilot, the Guardian can help take the fear factor out of the first few flights. If you get into trouble, just let the sticks go and the Guardian will attempt to quickly bring your model back to level flight, rather than in pieces on the ground.

If you are flying a plane that is not very stable due to imbalance, poor aerodynamics or high motor torque, the Guardian can make things much easier.

Is it moderately gusty or windy? The Guardian helps compensate for non-ideal flying conditions. The Guardian helps your plane fly like it's a perfectly calm day!

In 3D flight mode
, the Guardian becomes your aerobatic assistant. Whether you want to become a 3D expert, or already are, the Guardian can turn your squirrelly stunt plane into a kitten, without sacrificing aerobatic capability.

The Guardian updates your control surfaces much faster than most humans can, to provide real time corrections to the flight. So, you can concentrate on your maneuver, rather than fighting the model to maintain control. The Guardian makes your plane "snappier" for precision maneuvers.

In 3D heading lock mode, simply center your sticks to have the Guardian lock onto your present attitude (pitch, roll, and heading), which can make it easier to perform stunts like prop hanging, inverted flight, knife edges, low speed harriers, etc!

The Guardian weighs only about 11 grams with cable, and has a tiny footprint, so it is perfect for most models, from small foamies on up. But don't let its small size fool you - it works great in almost any fixed-wing plane! And, there are no external sensors to add drag or weight to your model.

The Guardian controls a total of 4 servos, and is flexible enough to support elevons, dual ailerons, and other configurations.

Note that the Guardian presently supports fixed wing planes, but we are considering versions for helis and quads. Please let them know if you are interested!

Yes! We offer two solutions for FPV flyers. If you plan on using an OSD that has built-in stabilization, we recommend the
, with the
Guardian Expander
. This gives you integrated FPV stabilization with AHI (artificial horizon) display, easily adjusted with on-screen video menus.

If you don't need an OSD with your FPV plane, or are using an OSD that does not support stabilization, the Guardian 2D/3D Stabilizer is perfect for you.

Guardian installation is quite easy. Simply mount the Guardian securely in your model's fuselage, and
connect it to your reciever and servos. The labeled receiver connectors on the included cable make this step very simple. There are no additional sensors or other hardware to install!

At a minimum, your ailerons (or rudder) and elevator need to be left connected, but the Guardian includes additional control and stabilization channels to support almost any model! Stabilization gain can be controlled via an extra knob on your radio, which lets you easily adjust it in flight.

After installation, the Guardian is tuned to your plane using only a small screwdriver, and settings are chosen via your radio sticks.
No computer or other device is required for configuration

Gain can also be adjusted in the air with a spare knob or switch on your reciever, if desired.

If you prefer PC setup, just connect the Guardian to your Window PC or laptop via the built-in USB connector*, and run our software to perform advanced configuration with ease!

Our PC software also allows you to save and restore model profiles, making it easy to move the Guardian from plane to plane without reconfiguration!

The Guardian's built-in state of the art sensors constantly measure the gravitational forces and rotation of your model in 3 axes. Using the sensor data, the Guardian's processor performs complex calculations thousands of times a minute to keep track of your model's orientation.

Previously, the only stabilization systems available required installing external sensors, or were relatively large, heavy and expensive. The Guardian changes all that.

At only $74.99 (USD MSRP), the Guardian is priced much lower than any other inertial based stabilization systems, and is much ligher and smaller than anything else out there, at any price.

And of course, it's an Eagle Tree product, so it's massively configurable and has built in USB* for advanced configuration, model profile save/restore, and firmware update from the internet. No need to return the unit to the shop or buy a USB convertor board for new firmware updates!

The Guardian has a built-in data port, and we have plans for future sensors and hardware features. Please let them know what else you want the Guardian to do!

The Guardian Stabilizer is now in production, and we anticipate shipping in late spring.
