eLogger^TM V4 - the Easiest Way to Monitor your Model's Power System!

New! Whether you’re into Electric Model Planes, Helis, Cars, Boats or other models, you need to know how your electric power system performs under actual operating conditions. The eLogger is the product you need to monitor your LiPo, A123 or any other electric power system.

Here are a few of the enhancements with our new eLogger V4 (click here for more details):

• High speed logging at up to 50Hz (increased from 10Hz).
• Sixteen times the logging capacity of the standard eLogger V3.   Typically logs all available sensors for about four hours, at 10Hz.
• Voltage logging increased to 80 volts maximum.

The eLogger system comes with everything you need to log, analyse, and graph mAH, Current, Wattage, Voltage and throttle position, right out of the box. And, your eLogger is tremendously expandable, by adding additional sensors (shown below).

Why should I choose the Eagle Tree eLogger?

Some ESC manufacturers are adding data logging to their products. However, these logging capabilities are limited, have very short logging times at high sample rates, and few if any additional sensors are available. While these built-in solutions may "whet your appetite" for data, our eLogger and its incredible array of sensors and powerful software will let you measure virtually anything you will ever need.

Also, investing in logging add-ons that are tied to a particular ESC means that the investment is only good as long as you use that ESC. Eagle Tree telemetry is portable across any ESC brand/model.

Finally, while the ESC manufacturers and others may lose interest in their logging capabilities if they don't sell well, you can rest assured that Eagle Tree will continue to enhance and expand our eLogger with additional features and sensors. Data is all we do!

PowerPanel LCD Display - a Gas Gauge for your Pack!

Now you can connect our PowerPanel lightweight LCD Display module to your eLogger!

This ultra thin LCD display connects to the eLogger with the included 11" data cable, and lets you get your max and live data displayed without a PC, just like the heavier, non-logging WattMeters on the market.

The display is fully programmable to show you your live and max Voltage, Amperage, Wattage Temperatures, RPM, mAH used, and more! Since you can know your mAH after your session, you know approximately how much juice is left in your pack!

Just connect it after your session for readback of live and max data. Or, since the PowerPanel is so light, it can easily be attached to the side of your model for live/max display all the time!

NEW: Video OSD Pro Expander (ETS-OSD-PRO)
Fly or race with video? The Eagle Tree OSD Pro Expander provides easy to display real time model data over your existing video link.   Click here for details

NEW: Altimeter MicroSensor V4 (ALTIMETER-V4)
This sensor measures altitude with approximately 1 foot (0.3 meter) resolution. And, it runs standalone as a Max Altitude display sensor as well as connecting to the eLogger, or with our OSD Products! Click here for details.

NEW: 3-Axis G-Force Microsensors

Need to know how many G's you pulled in that last barrel roll? Eagle Tree is pleased to offer the world's first standalone G-Force meters for RC models.  

The low G sensor measures up to 8g (at least 7g) in each of the 3 axes. The high G sensor measures up to 40g (at least 38g) in the X and Y axes, and up to 8g in the Z axis.

The sensors run standalone as a Max G-Force display sensors, as well as connecting to the eLogger, or with our OSD Products! Click here for details

Airspeed MicroSensor V3 (AIRSPEED-V3)
This sensor measures airspeed from approximately 2 MPH to 350 MPH. And, it runs completely standalone as a Max display sensor as well as connected to the eLogger, or with our OSD Products! Includes Pitot tube. Click here for details.

Brushless Motor RPM Sensor V2 (RPM-BRS-V2)
Tiny sensor measures RPM by simply connecting a wire from one of your brushless electric motor leads to the sensor. Click here for instruction manual.

10Hz GPS Expander Module (GPS-V4)
New GPS Expander Module based on the latest GPS technology. Built-in LED which indicates 3D fix.

Our software lets you view your recorded GPS data in Google Earth^TM and Google Earth Track^TM!

Fast 10Hz update rate. Built-in battery backup for quick fixes. Integrated toroid and onboard filtering greatly reduces the affect of RFI from your FPV video transmitter.

Plugs into the eLogger V4 or V3 to provide live and/or recorded lat/lon, ground speed, GPS altitude, distance to pilot, course, UTC timestamp, and more. Integrated display/3D graphing software included in data system. WAAS and EGNOS compatible, built-in patch antenna.

NOTE: if you plan to use the GPS with your eLogger with 8S (approximately 30V) packs or higher, the Battery Backup Harness (CAB-BAT-BACK) below is required. Click Here to view Instruction Manual

Servo Current Monitor (SERVO-CURR-LOG)
Find out how much current one or more of your servos or other low current devices are drawing. Plugs into your eLogger and servo (or receiver battery/BEC) to log current from 0-5 Amps continuous, with 0.01 Amp resolution. Click here for details.

Micro Temp Sensor
(TEMP-MICRO)

Perfect for measuring temps of your batteries and ESC. 250 degrees F max temp.

Up to three temperature sensors can be connected to the eLogger V4 or V3 simultaneously (two simultaneously for the V1/V2).

Temperature Sensor (TEMP-LOOP)
