The Flytrex Core is the world's first multi-rotor black-box that records your flight parameters with each of your flights. Combined with the complimentary Flytrex service on our site: www.flytrex.com, pilots can log and manage each of their flight details, analyze their piloting skills and improvement over time, track personal records, earn badges for different achievements, find other nearby pilots, manage multi-rotor fleet and much more. Flytrex is designed for newbie and proficient multi-rotor enthusiasts flying LOS and FPV.

Installation Guide

We love simple things, so we worked hard to design the simplest installation possible. Flytrex Core 2 installation connects seamlessly with your flight system, no soldering is required, just plug&play.

  • Disconnect your GPS from your flight controller.
  • Connect the GPS to the Flytrex Cable female socket - the only one available in the cable.
  • Connect the male socket on the same side of the cable to your flight controller GPS slot.
  • Connect the other side of the Flytrex Cable to the Flytrex Core slot.

Micro SD

Flytrex Core records your flight details to a micro SD (card not provided with package). You can use any micro SD between 256mb to 32GB formatted with 16FAT or 32FAT - so most micro SD cards will work right from the box. 1GB gives you approx 40,000 minutes of flight recording. Card must use basic microSD technology (micro SDHC and similar technologies are not supported).

Flying Without a Micro SD

The Core 2 adds a new internal memory chip that records your flight data at all times, whether a microSD is currently plugged or not. Using the new internal memory the Core 2 introduces new mode of operation without a microSD. This ensures that your flight data is always available - even if you forgot your microSD, or, during extreme flying when the microSD recording isn't always optional.

To copy flights from Flytrex memory:

  • Using your PC, add an empty text file named "backup.txt" to the microSD root folder.
  • Plug the microSD to Flytrex and powerup your multirotor so that Flytrex will receive power.
  • When the Core 2 recognizes this file it starts-up in Backup Mode. In Backup Mode it copies all missions from the memory to the microSD. During this process the LED will flash. This can take up to 2-3 minutes, depending how many new missions are stored on the memory.
  • When done, the LED will stop flashing completely.
  • Once done, you will find all mission files that were loaded from the memory waiting on the microSD. Unlike regular mission files, those loaded from the internal memory start with the letter 'B'.

Notice that when starting Flytrex in Backup Mode the system won't record the current mission at all - not to the microSD nor to the memory. You will need to pull out the microSD and remove the 'backup.txt' file to start recording new flights on next power-up cycle, or, power-cycle Flytrex without a microSD to start recording to the internal memory again.

Frequently Asked Questions

1. Can I use Flytrex Core with the DJI Phantom quadcopter?

Yes. Flytrex works perfectly with DJI Phantom quadcopter. Many Flytrex users are using it with the Phantom. However, due to the unique structure of the Phantom you will need the special Flytrex Phantom Cable that lets you mount Flytrex on the Phantom.

When ordering Flytrex Core, Phantom users should also include the Flytrex Phantom Cable (you will find this option in the ordering form). This cable was designed especially for the Phantom and lets you easily mount Flytrex on the Phantom. For more details about the Flytrex Phantom Cable check see the user manual.

2. Do I need to fly in GPS mode for Flytrex to work?

No. Although Flytrex requires the Naza GPS component to work, you can fly in any mode you like: GPS, ATT or Manual. However, even though you can fly in any mode you like, for Flytrex to work you'll need decent GPS reception. Flytrex won't work when flying inside buildings or in other places with poor GPS reception.

To verify decent GPS reception is available we recommend warming up your multi rotor in GPS mode while still on the ground, and only after your Naza indicates decent GPS is available switch to the desired flight mode and take off. Changing flight modes during flight is also no problem at all.

3. I just uploaded a new mission to my profile but the mission time seems to be 16 hours off the actual time of my flight. What is the cause for this?

In some situations, mission time can be in 16 hours offset when using Flytrex Core together with the DJI Naza flight controller (or a quadcopter powered by it, such as the Phantom). This issue is caused due to ambiguous data received from the Naza GPS that can't be parsed completely and makes it impossible to determine the exact hour of the flight. In such cases the Flytrex algorithm will try to automatically determine the actual time of the flight, but might fail to determine the correct time in some cases. When this happens, the time will be off by 16 hours. Although this might happen, most of your missions will show the correct time. This issue only affects the Flytrex Core and won't happen when using the Flytrex Live system.

4. I just logged in to Flytrex for the first time. How can I start uploading my missions?

Mission files are created using our Flytrex Core system. If you don't have a Flytrex Core system yet you will first need to order it to start creating mission files. Once you received and installed your Flytrex Core on your multi-rotor it automatically creates mission files with every flight mission you do.

If you already own Flytrex Core and looking for more details how to actually use it, please see this section in the user manual.

5. I'd like to use Flytrex but without sharing my flights with everyone else. Is it possible?

Yes. For each mission you upload you can set its privacy level: Public or Private. Public missions are shared across the Flytrex site and are visible to all other pilots and site visitors.

Setting a mission as private will keep it that way. Private missions are only visible to you, on your personal Profile tab. Private missions are not shown in any of the public views, the Explore and Globe views, nor is it listed in any of the badge statistics in the Badges view. Select the desired mission privacy level is done in the mission preview view, just after selecting the mission file to upload and before hitting the Publish Mission button.

In addition to setting up mission privacy for each mission you upload you can also configure the default mission privacy for newly uploaded missions through your account settings. To access your account settings click your account username on the top-right corner.

6. How can I determine the privacy level of a published mission and toggle its privacy?

You can check whether a published mission is public or private by checking the bottom right corner of your mission's box in your Flytrex Profile page. If the mission is private, you'll see a small padlock icon at the bottom right corner. If it's public, the bottom right corner will be icon-free.

To toggle the privacy of your mission find the mission you'd wish to change on your Flytrex Profile page. There you'll see a small triangle in the top right corner of this mission's box. Click this triangle to open the mission drop-down menu. Select 'Set Mission as Public/Private' to toggle this missions privacy level. You'll notice the private pad-lock icon visibility changes as you toggle this mission's privacy status.

7. I just started using Flytrex but pressing the Upload Mission doesn't seems to work. Other parts of the site also doesn't seem to work.

Our site uses HTML5 technology. When visiting Flytrex site with an older browser, without HTML5 support, parts of the site won't operate properly. For the best user experience you should use a browser with HTML5 support. The latest versions of all major browsers includes HTML5 support, including Chrome, Firefox, IE10, Opera and Safari. Visit HTML5 readiness for latest status.

8. How can I edit an existing mission details? Add or update mission video? Change title or update the aircraft linked with the mission?

In many cases you might need to update some details of an existing mission, such as adding a new flight video to your mission, update it's title or set missing aircraft details. To do so, visit the Profile tab and navigate to the desired mission. Then click on the mission-menu button (small down arrow on the right side of each mission title), and select "Edit Mission". Using the Edit Mission dialog you can update the mission title, update mission video, set mission aircraft and change mission privacy settings.

9. I just uploaded a new mission and the Max Altitude seems much higher than my actual flight. What is the difference between Max Altitude and Max Ascent?

With every flight mission you upload you will see two altitude related values: Max Altitude and Max Ascent. Max Altitude shows the max altitude you reached relative to sea level, so if you're located on a hill or high mountain your Max Altitude will reflect this. The second value, Max Ascent, shows the maximum ascent you reached in your actual flight mission and is relative to your starting altitude.

10. Is it possible to use my Flytrex data with other apps such as Google Earth?

Yes. Flytrex offers exporting options to Google Earth KML format and to CSV format for use with different applications such as Excel, Dashware and others. To export your Flytrex mission visit your Flytrex Profile page and find the mission you wish to export. Press the down arrow shown on the right side of the mission title. From the popup menu that opens select the Export Mission option to open the Mission Export tool. Use this tool to easily export your mission data to either KML or CSV format.

You can download a sample CSV mission export file here, and a sample KML mission export here. Note that the voltage field in the exported file only exists if the mission was originally recorded using the Flytrex Live or Flytrex Live 3G.

11. I just uploaded a new mission to my profile but the mission time seems to be off by 16 hours from the actual time of my flight. What is the cause for this?

In some situations, mission time can be in 16 hours offset when using Flytrex Core together with the DJI Naza flight controller (or a quadcopter powered by it, such as the Phantom). This issue is caused due to ambiguous data received from the Naza GPS that can't be parsed completely and makes it impossible to determine the exact hour of the flight. In such cases the Flytrex algorithm will try to automatically determine the actual time of the flight, but might fail to determine the correct time in some cases. When this happens, the time will be off by 16 hours. Although this might happen, most of your missions will show the correct time. This issue only affects the Flytrex Core and won't happen when using the Flytrex Live system.

12. I just finished a long distance flight with Flytrex, however, the max-distance is showing a shorter distance than the actual distance to the furthest point of my flight. What is the cause for this?

In most cases this happens if your landing point is different from your take-off point. Since Flytrex is all about multirotors and challenges, Flytrex algorithms measure the max-distance as the longest round-trip performed in a single mission, and is designed to ignore one-side trip. This means that is you landed half way back from your take-off point, the max-distance value will only be half of the absolute max-distance of your flight. This max-distance definition is designed to eliminate one-direction flights and defining the max-distance challenge to measure the longest round-trip flight.

13. How can I delete an aircraft from my profile?

Enter your Gear page by clicking on the aircraft image on the left side panel of your Profile page. Hover the image box of the aircraft you wish to delete and two buttons will show on the right-top corner of the image: "Delete" and "Edit". Press the Delete button to completely delete the aircraft.

Although deleting an aircraft is possible, it is not recommended to delete an aircraft. Deleting an aircraft will un-link all existing missions currently assigned to this aircraft and will list those missions without any aircraft. Instead, we recommend editing the aircraft and marking it as "Retired". Marking an aircraft as retired will no longer show it in your profile, but will still keep old missions linked with the retired aircraft and maintain stats that were collected for this aircraft. To mark an aircraft as Retired click the Edit button instead and change the Aircraft Status selection box to Retired.
