Hi, I need to be able to use GPS to record live flights. Besides this device need anything else? I have a camera Turnigy 30FPS Ultra-Mini DigiCam You can use this device?, I may lose the information collected to a PC? I need software? Tks

You can use this GPS in two ways: A) To record data on the plane and after landing to download them to your PC - you need an eagle tree E-Logger for this OR B) To see live info as you fly using a monitor - you need the eagle tree E-Logger and the OSD for this (google FPV to see what this option is like)

Thanks for your help DK3131, I want the option A, E-Logger What do you recommend to start? , And tell me you can mount the camera "Turnigy 30FPS Ultra-Mini DigiCam".? My idea is to mount it on a quad. And burn down the flight and after the flight information to a pc, flight altitude, speed, distance traveled etc etc etc. I leave for another time live flight.

To record and download flight data (altitude, speed, distance, current consumed - and also flight path on google earth) all you need is e-logger gps. Sorry, I dont know this camera

Camera is not connected to GPS or Datalogger. For on screen display of flight information you need to connect camera to OSD(pro) and connect OSD(pro) to Datalogger. The OSDpro also lets you connect throttle elevator aileron for airplanes (not for heli/multicopter) and can do Return to home autopilot...for airplane (fixed wing)

Excellent addition to the micropower V3 logger. Can log speed, distance from operator, altitude as well as the vehicles course.
Acquires a fix very quickly, usually within 30 seconds in my experience.
Accuracy is excellent for logged parameters (speed, course, etc) though general co-ordinates are slightly off (~2-5m).
May greatly reduce logging time depending on parameters selected. In a 1/8 electric buggy I have ~10mins at 4 samples per second with 2 temp sensors, brushless rpm sensor, basic eletrics (amps, watts, volts) & all GPS.
I had ~30mins prior to adding the GPS expander.
The eagletree software (micropower V3) also allows you to view the data in 2D or 3D graphs and makes it possible to save recorded sessions to view in Google Earth.
Not really a necessity, but great for informational purposes (esp. speed!).

Will log 30plus minutes of data on an eLogger V3. You can do 3D charts using Google Earth as a background (awesome). Acquisition takes under a minute in a new location, almost instantly if you fly in the same location as the previous flight. Great for your plane, boat, rocket, heli or just fire it up on the dash of your car to track and plot your trip to the corner store when you are not flying!

Excellent device. Logs very accurately in adverse conditions, even upside down (i.e. inverted hovering on a CF/Alu heli).

Very light at slightly over 10 grams and quite small - wires are about 40cm long so you can choose an optimal spot to mount it.

Highly recommended - the only time it has trouble getting an accurate position/speed reading is when the vibration level is too high (try mounting it on a soft pad to fix that if necessary).

Great product at a great price. I've flown four test flights with it so far and it's working perfectly. I'm using it with the Eagle Tree OSD and a video downlink, so I can see all the GPS info in realtime, in addition to logging it on the V3 for reviewing later.

If you power up where you flew previously, it acquires GPS fix quickly. At a different location it can take a minute or two on a sunny day, or up to 5 minutes if its cloudy.

I can absolutely recommend this GPS.
I had the GPSv3, new GPSv3 and now the GPS v4.
I it is very small and light weight.
Reception is very good and with 10HZ is really fast.

thanks Eagletree and HK
