Eachine VR D2 Pro Focus Adjustable

Just over 3 years ago, we had a challenge finding an affordable pair of goggles for FPV, let alone a DVR.  Eachine VR D2 Pro Upgraded Goggle delivers an All-In-One (AIO) solution with built-in diopter correction lens, a DVR, dual diversity receivers, with RSSI, includes a tripod mount and best of all within budget   ■ dronemission.com

User Segment
FPV Piloting, Off the shelves.   Budget [$] (PRICE CHECK: $89.99 ■ May 2017 Arthur’s Pick)

What To Expect

This is what I have been waiting for, corrective lenses for people who wear glasses, nearsighted, this helps just a little, I wouldn’t say it is compatible for everyone, but I can now read the osd without glasses having been using -2.0 diopter on all my other goggles.  I have the lens slide all the way to the front.  There is a slider on the left and right, and you just adjust it to best fit your eyes.

The menu system is broken down into 5 sections.

What I like about the upgraded functions are the On Screen Display (OSD) and Recieved Signal Strength Indicator (RSSI).   The voltage of the goggle battery and frequency selection is shown; it is not recorded, but overlays on your screen. It is suggested that we calibrate the RSSI before each flight. The A&B signal strength helps me identify the direction of a lost aircraft to some accuracy, as you can hold the goggle against your chest and rotate around, and then foolow the direction with the strongest signal.

It accepts upto 64 gb of memory storage and records at 16000 kbps Bitrate at 29.97 fps.


There are 40 channels, a quick autoscan to select the channel.

Eachine Micro Skyhunter 780mm FPV RC Airplane

Skyhunter, has been an all-time favorite plane for lots of long-range FPV pilots. Eachine doing it’s match, takes on the micro version, at 780 mm, 3 channels, plug and play.  Take a break from the racing drones, here comes a racing plane.   If you are looking for a budget, simple hand launch RC FPV plane with some speed, you may be in luck.  ■ by Leo @dronemission.com

Keen Beginners, Park Flyers, Plug and Fly, Budget $59 BNF (source: Dec 2016 Banggood)

What To Expect

The Micro Skyhunter FPV is one of the coolest miniature version of the Skyhunters released under the label of Eachine.  I have here the FPV version with 40 channels and 800 tvl camera which you can just slip on or remove anytime.

The Skyhunter comes in this small box just under 1 1/2 feet, very well pack, box in a box and individually wrap.  All electronics are pre-assembled,  plug and play, so you can begin flying on the same day.  It comes with a few cabon fiber spars, the main spar and re-enfocement along the wings.  You can see the signature look of a skyhunter with two veritical stablize.  I like how everything is pre-installed, 5 grams servo, servo linkages are all ready using JR connectors.  Included is a Hobbywing 20 amps electronic speed controller(ESC) with a XT 60 plug.

There is plenty of room, you have three separate compartments, one section for your receiver and flight controller if you are using one, and a two in one canopy held on by magnets for the battery and a convenient camera fpv bay.   The wings are held together with two bolts.

The camera is pretty good, other than the 25 mw range limitation, we have no complaints. You can of course always use a different video transmitter.  There are some crack lines, along the joints, but nothing too serious, I just add a little tape along it and tape along the leading edges, wing tips and base for additional protection and to prevent wear and tear.

eachine-micro-skyhunter-unbox.jpgMotor is powerful for this size plane, 2300 kv 2204.

The camera comes with a holder plate, very nice, and you simply secure it on the camera bay when in use.  I just tape the plates down for easy removal.

Decals are included, but I like my usual red/blue white colors.

Overall, this plane has everything you need, easy to assemble as all the electronic are installed.  It uses XT 60 which means LiPo batteries are easily available in the market.  The bigger question is, are you up for a 3 channel plane, if you are, this is definitely a keeper within budget.

Flight Characteristics

Tracks very well, but not a great glider.  We are currently completing a few more flights before reporting back.  Standby.

Camera & Video Transmitter

The camera is okay, a 40CH 25MW VTX 800TVL 1/3 CMOS FPV Camera.  See video for results.

Upload 360 videos Youtube

What the Andoer Dual-lens 360°, Ricoh Theta S and Samsung Gear 360 have in common are the dual-lenses that allows you to film and upload 360-degree videos.  This give rise to a new perspective if drone aerial first person view

YouTube and Facebook now supports uploading and playback of 360° spherical videos. To watch 360° videos, you need the latest version of Chrome, Opera, Firefox, or Internet Explorer on your computer. On mobile devices, use the latest version of the YouTube app for Android or iOS.

(Flipboard not compatible. Best viewed in youtube app directly by opening this link https://youtube.com/360)


For an immersive experience, you can even watch 360° videos with a cardboard goggle attaching the YouTube Android app.

After a week of filming, we begin to discover that is just a few things to consider before creating the video.

  • Decide the best way to mount the camera without appearing to be holding a tripod or showing too much head (realizing you are being filmed no matter where you stood in 360).
  • What if you want to incorporate text on the video or include a logo, not knowing if your audience is looking front, back, sides, down or up.
  • Storyboarding and sequencing scenes in 360.  How do you you mix 2D and 360 footages.

The following 360 cameras are compatible with YouTube and are available today:
• Andoer Dual-lens 360° (budget $125 source: Nov 2016 camfere.com)
• Ricoh Theta S
• Samsung Gear 360



For the best results, encode your video at a high resolution and according to YouTube’s advanced specifications. YouTube currently supports 360° videos with 24, 25, 30, 48, 50, or 60 frames per second. We recommend uploading 16:9 aspect ratio stitched videos in 4K (3840×2160) resolution as a loss of resolution is inevitable when playback in youtube 360. A 1080p video, when stretçhed and wrapped around the sphere will look like 480p.

When uploading your 360° video, don’t make edits to the video using the YouTube Video Editor and Enhancements tools on desktop or mobile. These tools don’t currently support 360° videos.

Before publishing, schedule the video for a later date and verify that the file has 360° playback enabled by watching the video on your device. It may take up to 30 minutes for 360° playback to be processed after uploading.

360° videos on a browser feature a pan button in the top left, and can be rotated using the WASD keys, so look for these features to confirm your video is in 360.

If you take the video straight out of the camera and try to upload it to Youtube, it’s not going to work properly. The video will upload and be available, but when you go to view it you’ll see a stereoscopic image–an odd-looking video of side-by-side circles, each showing the hemisphere captured by one of the two lenses.


To make it work properly there are two steps you have to do before uploading it.

1. You will need to convert the image from stereoscopic view to an equirectangular one. That will combine the two hemispheres into a wide view with dimensions where the width is exactly double the height (otherwise known as a 2:1 aspect ratio). And the tops and bottoms of the frames will look strange and stretched. But when used in a specialized 360° player those stretched parts of the frame will fill out when you look up or down, wrapping around the sphere 360.

If you own the budget Andoer 360 camera, you can use the recommended unregistered Symax 360 software – Open Convertor, set Video Quality = High, Start.

2. In order to upload and playback a 360° video file, you’ll need to modify the metadata of the video file with an app or script before uploading.

Follow these instructions to install an app that will add the necessary metadata into a new file for you.


  1. Download the 360 Video Metadata app for Mac or Windows recommended by YouTube
  2. Un-zip the file, then open the 360 Metadata Injector app. If you’re on a Mac, you may need to right-click the app and then click Open.
  3. You can also add the metadata using a Python script.
  4. Select the original or edited 360 video file
  5. Select the checkbox for My Video is Spherical (360) and click Inject Metadata. Do not select the “3D Top-bottom” checkbox. For more information, refer to upload instructions for virtual reality videos.
  6. Save the file that will be created suffix with “injected.mp4”.
  7. Save the file. A new file will be created automatically in the same location as the original file.
  8. Upload the new injected file to YouTube.
  9. Wait for the 360° conversion to process. This may take up to 30 minutes for a 7 minutes video.

Tip: Andoer Dual-lens 360° 960p on Premiere Pro, follow 1920x 960 size, h.264

Mobius Mini Camera

Mobius Mini at 27 grams is a major achievement, filming at 1080p 60fps with an amazingly low latency for FPV.  You can almost add this mobiusmini camera to any 150 size quadcopter or 800mm airplane.  We took it for a test flight, compare it with the FireflyQ6, unbox it and review the design.

Wow…  MobiusMini has a very low latency! had a good flight with the mini and have included the latency test results. Says a fraction of a thousandth of a second, subject to your own interpretation. See for yourself and pause your screen to subtract. A snapshot is a frame in time, regardless of what you are viewing with.



Mobius Mini weighing 27 grams


Notes: because the power and record buttons are on opposite sides, I am finding myself accidentally setting it to recovery mode, which then makes the camera not turn on, until you reset it with a pin or paperclip.



Lower-weighted to the ground for FPV



In terms of ranking, I would say it is in the top 5 favorites during this release recorded September 2016.  An update to follow.  (Current Picks dronemission.com/top5).

AOMWAY FPV 200mW 700TVL AV Transmitter

If you are looking for a quick way to view the world from the sky, the Aomway Mini video transmitter packs 200mW of ultra clean 5.8GHz power in a micro sized video/audio package integrated with a 700 TVL camera.  That’s right Plug N Play FPV! and at 19 grams!  ■ by dronemission.com

First Impression,  love the fact that it is plug and play.  Easy to use, just deciding how you want to power this FPV gear is the only challenge you may have or maybe not.  It comes pre-wired with a standard JST battery plug, allowing you to use any battery type, not limiting to AA or LiPo.


User Segment
Beginners, Park Flyers, Plug N Play, Budget $52 (source: Aug 2016 Banggood)

What To Expect

The AOMWAY FPV 200mW 700TVL can get hot with a 3s LiPo.  We had tested it with a 2s and 3s LiPo with no issues. It did not broadcast any sound during our test.  The stock range at 200 mW is 1.2km and by changing the antennas on both ends, you can reached upto 3 km.  There seem to be distinctive vertical lines appearing on the broadcast.


The camera is a 700 TVL camera, with a 170 degree field of view.  The focus range 6 feet +, does not focus well at closeup.  See video for results.

Things you might need to know

  • Input voltage 6-28V
  • Powering plug is JST
  • Antenna connector is a SMA, if you use to use your own
  • Weight is 19g without the antenna

ZEROTECH Dobby Pocket Selfie Drone

The highly anticipated DOBBY is here and in our lab, compact and optimized for photography, taking pictures by voice control and gesture control, assisting users to capture the perfect selfie “Kodak” moment of this generation.

DOBBY Pocket Drone is an AI-powered drone using Qualcomm Snapdragon 801 chipset, piloted with GPS and GLONASS, featuring object tracking and facial recognition. DOBBY can take off by voice control and one click on APP. Selfie lovers can enjoy creative photos from unique perspectives rather than taken by other shooting tools like cell phone cameras.

If you are into smartphone technology Qualcomm comes to mind; anyone who uses Wechat or QQ knows what Tencent can do.  Known to few, the two giant firms are among the core influence to bring ZEROTECH to the limelight with Dobby. However with all that investment backers and publicity behind it, there seem to be an underlying issues uncovered as we take it for several tests.


First Impression
The highly anticipated crowd funded DOBBY quadcopter is here.   The DOBBY Pocket Drone came in a familiar box looking like an Apple product.  Very elegant indeed.  In the box, you will find a folded quadcopter, a size of a smart phone.  Included is a USB charger,  usb adapter, a proprietary smart battery,  basic instructions and warranty card.

What I have found is you may need to use the USB charger provided, as a generic charger may not feed enough power.  You can tell by looking at the light, if it does not turn orange while fast charging.  The battery last just about 7 minutes or less in flight.   You can check the battery status by pressing the status button.

Video and photos are recorded directly on to Dobby internal memory storage (no SD card needed), I believe about 9 GB of free space.  It is viewable when connected and can be downloaded on to your device. Video and photos are sharp and crisp I must say.  Videos have a jello movement to it, due to amount of vibration generated by the hinged propellers.  The best way to transfer your video and photos to your computer is to attach the USB cable with the adapter and connect your Dobby to a computer.  A new USB device will be detected and a new drive will be assigned, where you can just drag and drop your files over to your computer.

Before each flight, you begin by extending the arms, it locks in when fully extended.  You then adjust the camera angle manually.  They lock in to each fixed angle to match the app image stabilization.  45 degrees is required if you plan to use the Follow Me Target feature.  You can have the camera face directly down for a full unobstructed aerial view.

At the current moment 720P is all I can record, but my understanding resolution should be higher.

The camera orientation is default to selfie, face to head, so careful with it, the quadcopter will be flying reverse.  You can change it to Face to Tail, the more convectional way of flying RC.

You can see here, the Optical Flow and ultrasonic sensor, which helps with position hold, palm take-off and palm landing.  The ultrasonic emits a sound wave that the human ear is unable to detect, but may be sensitive to some animals, so keep your pets away.

The firmware and guide has just been released after several months.  Make sure to update your Do.Fun app which will then prompt you to update the latest firmware.  The latest user guide can be found within the Do.Fun app.

User Segment
Selfie Addicts, Beginners, Park Flyers, Ready To Fly, Off the shelves, Collectors, Budget $409 (source: August 2016 Banggood Price Check)

What to Expect

The Dobby has difficulty picking gps signal indoors, not that we recommend that anyone fly indoors.  In novice mode it will not take off without 7 gps count.  We suggest that you fly outdoors as it is too hazardess indoor, besides the optical flow sensor requires sufficient light to work properly.

It is a selfie drone, so careful to face the camera to yourself, or you will find yourself flying in reversed.  Remember the camera is on the tail end of the quadcopter.

It is clear that Zerotech had release the product prior to the functionality being complete.  The App was updated late August 2016 to support some of the functions promised, but seem to require more testing to be comfortably certain it works.

Target function requires the Dobby to be over 5m function.  It does seem to recognize it is over 5 meters.
The flip function is always saying “low power, cannot use this function”
The Face recognition says “coming Soon”
The return home seem to be 6+ feet away

Eachine ProDVR Mini Video Audio Recorder

Eachine ProDVR is a useful mini digital DIY video recorder recently added to the long list of Eachine innovation. You can probably find a dozen applications yourself to put this little DVR to good use; some usage include using it as a micro Security CCTV DVR or recording video footage on a model aircraft. This mini DVR us especially popular among hobbyist. ■ by dronemission.com


First Impression, this mini dvr is an innovative digital image capture card, leveraging the use of micro Secure Digital (SD) storage memory card.  It does require a user to have some basic experience in wiring and soldering.  Once you have installed the cables, you can determine the compatible connectors needed to receive video and to output video to a monitor.

A few issues has been identified.  The current firmware is not able to record in (720*480) or (1280*480) resolution.  It is only compatible with NTSC and not correctly recording with PAL cameras.  A new firmware is expected to be released to correct these issues.
