DJI retracts Phantom 2 Firmware v3.10, urges users to roll back to 3.08

DJI retracts Phantom 2 Firmware v3.10, urges users to roll back to 3.08

February 6, 2015 23:20 | By | Add a Comment

DJI is urging users who already installed v3.10 of the recently released Phantom 2 firmware update to roll back to v3.08.

According to DJI, “there have been a small number of reported issues”. No word about what these issues are and how serious they were, but a warning is better than nothing.

P.S. Did you fix your compass sensor as we posted in the past yet? If not, you should do so, regardless of your firmware version.

Alibaba is a year late, also tests drone delivery

Alibaba is a year late, also tests drone delivery

February 4, 2015 10:44 | By | Add a Comment

Alibaba, the chinese online merchant / trade portal, had a fantastic launch on the stock market last year, with over 500 million customers and a net worth of over 200 billion USD, more than Coca Cola or Disney. Now they’re testing drone delivery, much like Amazon and DHL before them. A total of 450 customers were able to register for the special air-drop delivery, though the drone only flies from the outskirts of Peking to the China World Trade Center, where it is then picked up and delivered by a regular courier.

But hey, at least they produced a snazzy and mildly entertaining ad video. Notice the synchronously-waving guys at 00:45 🙂

DJI to update no-fly zones to prevent more White House incidents

DJI to update no-fly zones to prevent more White House incidents

January 29, 2015 12:35 | By | 1 Comment

In reaction to recent news that DJI multicopters were used to smuggle drugs and fly within Washington D.C., the company announced a firmware update that adds not only over 10.000 national airports, but also country borders and the FRZ around Washington D.C. to it’s no-fly zone list.

This will prevent owners of Phantom* and Naza flight controllers from repeating some of the the stunts seen recently.

At least, if they apply the firmware update, and even then only until they realize that open source flight controllers have no such restrictions.

Phantom flies onto White House lawn

Phantom flies onto White House lawn

A quadcopter enthusiast apparently lost control over his DJI Phantom, which proceeded to fly over to the white house and crashed onto the lawn, where it was found and recovered by Secret Service agents.

Folks, there’s two lessons here:

1) Flying any RC craft, regardless of whether you do it for recreation or not, within D.C. is illegal. There’s a 10nm FRZ (Flight Restricted Zone) which prohibits, among other things: balloon operation, model rocketry, model aircraft operations, UAS, test flights, private aircraft operating from a ship or private/corporate yacht, etc.

2) If you own a Phantom or Phantom 2, and you haven’t replaced the compass mounting on your landing struts yet, you risk your quadcopter flying away uncontrollably. This means your quadcopter may start flying into a random direction once you enable position hold or return home modes, with it not obeying any no-fly-zones programmed into the firmware. It will also not obey any user-defined geofencing or range limits.

DJIPH03-2

If your screws or the metal mounting mechanism is magnetizable, you run the risk of compass decalibration, even during flight. If you fail to do this, you run the risk of damaging other people’s property or lives.

In all the Phantoms we examined, the screws were magnetizable and the reason why compass calibration was lost. We recommend you replace them with non-magnetizable screws, for example, brass screws as used by Horizon on their 350QX.

Hubsan releases “plus” versions of their popular smaller quadcopters

Hubsan releases “plus” versions of their popular smaller quadcopters

January 15, 2015 14:47 | By | Add a Comment

The Hubsan H107D we reviewed some time ago turned out to be quite popular, and got many people into the FPV flying hobby. Now Hubsan is planning a “plus” version of this and two other toy-grade quadcopters.

SKU20006101The H107D+ above gets a 720P camera and a new stylish case. Apparently the stabilization has been improved as well, though that remains to be seen. Also, the remote receives and records in standard definition only, unless Hubsan abandons that and moves to an in-copter recording solution for the H107D+. Banggood lists a tentative price of USD $199.0

The H107C+ upgrades a few more things, adding a 720p camera and an all-new altitude hold mode. Not a bad deal for the alleged $99 price point thought of course it’s only recording video, not transmitting for FPV flight.

SKU200064-2

Finally the H107L, which has no camera, also gets a new look and an alleged stabilization upgrade for 50 bucks.

DJI Inspire 1 user claims bug in auto-takeoff function crashed his copter

DJI Inspire 1 user claims bug in auto-takeoff function crashed his copter

January 15, 2015 12:33 | By | Add a Comment

There’s a lot of hate in the youtube comments to this video. “Learn to fly” is probably one of the nicer ones. But comments aside, Mark Taylor had a bad day recently when he let his Inspire 1 take off in auto-takeoff mode.

According to him, no pilot input was given, the compass was calibrated and the issue was even observed before: His Inspire 1 just kept drifting off at auto takeoff.

While lots of youtube commenters are quick to blame Mark, we are not so sure. After all, DJI is still selling the Phantom 1 and 2 with a compass sensor mounted with magnetizable screws, which we found to be the root cause for most flyaway issues.

DJIPH03-2

We discovered that simply removing the metal case completely and using double sided tape to stick the magnetometer PCB to the landing gear made position hold much more precise and completely eliminated the need to recalibrate the compass after this has been done once. A miscalibrated compass can cause a flyaway if you switch your Phantom into position hold or return home mode. To this date DJI has neither acknowledged this simple design flaw, nor have they changed the mount on new Phantom 2 copters.

For this reason, we are a bit cautious about blaming the pilot just yet. The Inspire 1 is a brand new product and contrary to what some commenters may believe, DJI is not perfect.

Navio+ Raspberry Pi-powered flight controller now runs APM too

Navio+ Raspberry Pi-powered flight controller now runs APM too

January 12, 2015 15:41 | By | Add a Comment

The folks at emlid.com notified us that their promised port of the Arducopter APM code is now complete, turning the Navio+ board into a ready-to-use flight controller for your UAV needs.

SONY DSC

The Navio+ is an add-on board for your Raspberry Pi with all the sensors and equipment you need for your unmanned missions: MPU9250 IMU, MS5611 barometer, uBlox M8N GPS, serial UART, I2C, PPM inputs, a ton of PWM outputs, and even triple-redundant power source, switching from servo rail to Raspi USB power to a separate power module on the fly in case of problems.

The real interesting part is that the Raspberry Pi gives you a very open and accessible linux environment aboard your vehicle, with all the usual capabilities in addition to what the Navio gives you. Want to run  a special python script or some linux program you wrote during your mission? Now you can, and it’s a heck of a lot easier to pull of than trying to write custom code for the Pixhawk. Want to add wifi to your quadcopter? Just plug in a wifi dongle.

The Navio+ is available for preorder for USD $168.- at their website, with the first units expected to ship early February.

Walkera H6 actually named “Voyager 3”, only a prototype

Walkera H6 actually named “Voyager 3”, only a prototype

January 7, 2015 14:30 | By | 1 Comment

German IT magazine heise.de reports from CES Las Vegas that the previously teased Walkera H6 was nowhere to be seen at Walkera’s booth – and was shown to them only on their request (German, Google translate).

According to Walkera, a communication problem with their american distributor led to the premature announcement, which was planned for end of January this year at the Toy Fare Nuernberg in Germany. Sadly, pricing and features are still secret until then, even though production is slated to begin “soon”.

Walkera H6 debut at CES, runs APM/Dronecode

January 5, 2015 12:43 | By | Add a Comment

Need more proof that APM and the Linux Foundation-backed Dronecode alliance is really taking off? Walkera is about to debut the H6, a fancy-looking high-end quadcopter with retractable landing gear. The design is reminiscent of the new DJI Inspire, though the construction uses a simpler landing gear mechanism instead.

No info on price or availability yet, though we expect this to be announced within the next day.

Stick around for more pictures after the break.

Hubsan X4 Pro features parachute rescue system, tablet-style remote

Hubsan X4 Pro features parachute rescue system, tablet-style remote

January 5, 2015 0:47 | By | 2 Comments

The Hubsan H109 is a bit of an endless story. Originally slated for release early 2014, so far it failed to materialize. Fast forward to 2015 and still no H109 – but Hubsan did announce the X4 Pro which appears to be an upgraded H109 with several quite unique features. Besides being a GPS-enabled quadcopter, it comes with a three-axis gimbal, a gopro-sized HD camera, 2.4GHz remote control and 5.8GHz video link, as well as a built-in rescue parachute. This quadcopter is scheduled to debut at CES Las Vegas – which is tomorrow.

SKU116107.013

 

The star of the show is the flat, sleek remote with built-in touch control for placing waypoints on the map, as well as a separate OLED display for telemetry data.

SKU116107.007

Banggood lists a tentative price of USD $499.-, which we’re very certain is not going to be the actual, final price – but according to Hubsan the final price will be below USD $1000.-

Video, Specs and more pictures after the break.

Upgrade your Naza-M lite to a Naza v2… for free

Upgrade your Naza-M lite to a Naza v2… for free

January 4, 2015 17:51 | By | 3 Comments

Thanks to the efforts of rcgroups user udnham (RCGroups removed his post and then closed the thread due to “legal issues”, surprise surprise…), you can upgrade your Naza-M flight controller to a Naza V2. Without paying hundreds of dollars for a box that contains the exact same hardware.

Yes you read that right. Not only does DJI use relatively low-performance accelerometer and gyro sensors (maxing out at 200 degree/s), they essentially sell the same hardware at a significant price markup with the software being the only difference. And since anything done in software can be undone in software, udnham has done just that and is now offering a free upgrade tool at http://naza-upgrade.com for  all Naza-M owners.

What does this upgrade give you? Well..

  • Better inflight algoritms – takeoff, landing, GPS position and altitude hold
  • Octacopters support
  • Ability to connect CAN-bus devices such as iOSD, zenmuse gimbal etc (using v2 pmu module)
  • Autonomous waypoint flight from groundstation with dji datalink modem
  • All other features that Naza-m v2 have

The tool works by circumventing the software locks DJI built in to prevent users from upgrading their flight controllers “too much”. It’s a non-official hack that basically turns your $160 flight controller into a $300 one. It’s unlikely that DJI will just continue to let this happen, so you may want to grab the tool before DJI yanks it, as the RCGroups post is already gone.

It will be interesting to see DJI claim any kind of legal issue here though. The firmware update is being distributed for free over the internet, the only thing the tool does is make the V2 firmware work on the V1 flight controller. Though we are not lawyers, this does seem to invoke the interoperability exception to copyright in most jurisdictions. Or in other words, if you buy a Lexus car, the manufacturer can’t really sue you for showing customers how to make cheaper Toyota brand parts fit in it. Then again, a new lawsuit may bring a new ruling…

Hubsan H301S adds GPS auto return

Hubsan H301S adds GPS auto return

January 1, 2015 20:04 | By | 4 Comments

Spyhawk early adopters were a bit miffed to find that Hubsan had canceled the planned release of an add-on GPS module for existing Spyhawk owners, citing technical problems. Well apparently there’s no problem releasing a brand new version of the Spyhawk that has GPS auto return.

Hubsan did update the original design multiple times, for example adding an actual external antenna on the transmitter instead of the fake rubber ducky.

The new Hubsan now comes in two colors (classic white and a snazzy new black version), adds colored LEDs on the wings, and of course features GPS guidance for an auto-return function. No word on any additional GPS flight modes yet, or whether this version will have the ability to disable the built-in gyro stabilization remotely.

Hubsan H301S-4

Banggood.com has a tentative price of USD $360.- but Hubsan has not confirmed the price yet.

If you are looking to add GPS auto return to an existing model for little money, you might want to consider giving the T1000FC we reviewed some time ago a try.

Specs of the new H301S after the break.
