Log or display(with OSD) live flight data!

Technical specifications:
- Logs pack current to +/- 100 amps (150 amps optional) and voltage from about 4.5 volts to 70 volts.
- Each unit is calibrated on a custom built calibration machine for the best accuracy.
- The eLogger V3 has 4x the memory capacity of the V2 (128KB).
- Current is measured with a true Hall Effects Sensor - NOT a resistance shunt which produces heat and sucks power from your system!
- Great for bench monitoring of battery charging also!
- Accepts optional inexpensive sensors for GPS, Temperature, RPM (brushless, magnetic or optical), Airspeed, Altitude, Servo Current, and more, available below
- Logs Throttle Movement with optional Y-Cable
- All data is logged to permanent memory, which retains the data even when the power is removed.
- Software computes Wattage, mAH, etc. for complete e-flight data.
- Fully Compatible with Windows Vista, 98SE, ME, Win2K and XPT
- Integrated USB with included cable (NOT a USB to serial port cable like other loggers)
- Weighs about 0.7 oz (20 grams). Version with Wire Leads weighs slightly more.
- Supports USB Live Mode, which lets you see what's happening in the model LIVE on the bench, on your PC
- Adjustable logging rate (1-10 samples/second) and lossless data compression for long log times
- Comes with our state of the art Windows virtual playback display and graphing
- Powerful Graphing software has advanced charting features, such as amps vs volts
- Internet Updatable firmware - as we add new features or (heaven forbid) have a firmware bug, the update is just a download away! No need to ship hardware back and forth.
- Full support for English and Metric units
