I’ve been flying drones for enterprise functions for six years now. Once I first had the thought of a drone enterprise, I did loads of analysis. I needed to be taught the totally different platforms, the enterprise alternatives, and the authorized necessities and guidelines. I earned my Half 107 certificates earlier than I began flying in order that I used to be not exterior of the principles and since I had not been concerned in aeronautics in any means prior, that was fairly an eye-opener.
I started with the Phantom 3 Superior and have crashed, traded, upgraded, and grown by way of 6 totally different plane, working now with the Phantom 4 Professional V2 and I exploit my Phantom 4 Professional as my backup.
Whereas I like the Phantom 4 Professional V2, there are 4 points that hassle me, and they aren’t a lot V2 points as a lot as issues that the Phantom 4 Professional and a lot of the Phantom plane additionally share.
- Impediment avoidance infrared aspect sensors are solely accessible in newbie mode and tripod mode and are usually not energetic on a regular basis.
- The Phantom 4 Professional V2 lacks an impediment avoidance sensor on the highest of the plane.
- You want to take a look at the accuracy of the impediment avoidance system your self, with the danger of crashing.
- The 12-volt battery charger you’ll be able to plug into your automobile takes an distinctive period of time to cost one battery.
Let’s work by way of these points collectively.
1. Facet sensor activation
For those who’re new to the Phantom 4 Professional V2, you’ll quickly uncover what I’m speaking about. The extra skilled Phantom pilot has in all probability already discovered this annoying characteristic and has come to phrases with it in a roundabout way or one other.
Moving into the programming of your plane you’ll marvel on the accessible settings for the hazard sensors. Now, DJI calls this their “Imaginative and prescient System” and the “Infrared Sensing System”.
The imaginative and prescient system sensors are on the underside, nostril, and tail of the plane. The infrared sensors are positioned on each side. There are management slide buttons inside the programming and you may select what to have on and off as your undertaking dictates.
If you’re scheduling your flight to be in very confined areas, you would possibly want to show off the imaginative and prescient system. Let’s say that you simply wish to fly nearer than 30 ft to a wall to do some detailed inspection. When the imaginative and prescient system is on, you’ll begin to get a warning on the RC, and once you get inside the established boundaries, the plane will cease lifeless the place it’s and never proceed one other inch.
That is very useful for cinematic flying the place you may want a sweeping fly-by of a hillside or ornate constructing, but when it’s worthwhile to get shut in for a nonetheless shot that you’ll want to enlarge, it’s worthwhile to flip off the imaginative and prescient system. Likewise, if you’re flying right into a tunnel, the decrease alarm will beep and restrict how low you’ll be able to go.
That is most irritating for me when I’m touchdown on the deck of my pickup and the plane is dealing with towards or away from the cab. The system will cease the AC from getting shut sufficient till I both flip sideways or flip off the system earlier than I can land.
Facet sensors in Newbie Mode
Nevertheless, the massive irritation is that the infrared aspect sensors can’t be turned on till you launch and put the drone into Newbie Mode or Tripod Mode. The “Newbie Mode” just isn’t described within the consumer handbook and might solely be discovered whereas looking by way of the management display menu. One can find this feature on the MC Settings web page, 5th merchandise down on the checklist.
It exhibits that “In Newbie Mode the plane can solely fly inside 30 radius of the Residence Level at considerably slower speeds.” This can be a superb thought for somebody new to droning, and an excellent thought when you have not flown your $1500 V2 earlier than.
However if you’re something like the remainder of us, by the tip of the primary battery you might be prepared for some actual flying and you’ll flip off Newbie Mode. So why did DJI select to make the infrared aspect sensors accessible in Newbie Mode? That reply is fairly apparent.
As a brand new pilot who’s simply studying to fly you need all of the safety and warnings accessible, however when you can solely fly 30 radius (I’m assuming that’s 30 yards or 30 meters relying on how you’ve set your measurement models) that’s shut sufficient that you need to be capable of visualize any obstacles in any course.
As novices, we’re so targeted on the place the drone goes and we’re watching it so intently that if we have been to listen to the controller beeping and light-weight arcs on the display glowing crimson, which will distract us from conserving visible line of sight. So I’m not certain that the infrared aspect sensors are of a lot worth in Newbie Mode.
In response to the Person Handbook, “Within the Tripod Mode, the utmost flight pace is proscribed to five.6 mph (9kph) and the braking distance is decreased to six.6 ft (2m). Responsiveness to stay actions can be decreased for smoother extra managed actions”.
It appears that evidently the one time DJI feels the infrared aspect sensors are wanted is when the drone goes slower than regular speeds. Additionally, you can’t begin Tripod Mode till you might be within the air, so it’s a must to take further steps to activate the infrared aspect sensors.
Nevertheless, I would love to have the ability to use the infrared aspect sensors in all of the modes. If I’m flying up a hillside in bushes or different vegetation, the warning of an object to the aspect could possibly be tremendously appreciated. I’ve flown across the prime of a hill a number of instances the place there was a brief lack of sight of the plane.
It certain can be good if I had some confidence that I used to be not flying into one thing to the left or proper. One other time I used to be flying by way of a gully with pine bushes on each side and climbed up in a cinematic shot. I had a transparent line of sight to my drone, and I noticed a tree simply past the V2 however the drone was dealing with away and I couldn’t inform how near the best the tree was.
Proper about then, I might have used a warning as a result of I moved an inch nearer, caught a twig, and crashed to the bottom. The V2 fell all the way in which to the underside of the gully. It was an extended hike all the way down to get it, and a few repairs have been wanted.
Why DJI has determined to not program the infrared aspect sensors to function for all flight modes is a thriller to me. I’ve contacted their helpline and chatted with an agent, however he mentioned he didn’t have the reply to that and would ship the query up line.
2. Lack of prime impediment sensor
One other frequent problem with the Phantom 4 Professional V2 is that there isn’t any sensor on the highest of the drone. Why not? I’d like to fly by way of a tunnel and never fear about rising only a bit an excessive amount of, or fly down a forest path and be relieved of the hazard of going too excessive.
Once more, DJI has made a design resolution with out actually consulting the individuals who purchase and fly their drones.
3. Impediment sensor sensitivity degree
The vary of hazard detection is said within the handbook as being between 50 and 70 levels to every aspect of every sensor, relying on which sensor is in query. Nevertheless, the gap of the hazard recognition just isn’t talked about in any directions, so the one strategy to decide the accuracy of the alerts is by testing it your self.
There are a number of variables to contemplate whereas testing and you ought to be conscious of getting totally different outcomes below totally different circumstances. For one factor, the floor of the thing you might be coming near may cause distinct modifications. A easy cement wall is not going to be detected as quickly as a wall of wooden slats which have a tough or textured floor.
A big boulder will present up earlier than a avenue or paved highway. Reflective surfaces register nicely however fences my not activate a warning in any respect.
The one strategy to discover the accuracy degree of your V2’s impediment avoidance system is by particular person testing and experimentation. If in any respect doable, ask an observer to assist out then exit and discover a number of totally different surfaces to work with.
Place your observer and your self at totally different angles to the thing and preserve issues low to the bottom. Strive testing towards bushes, bushes, constructions, and floor areas. The pace you fly at also can change the distances which might be detected. The quicker you fly, the much less house your plane has to reply.
4. Battery life and charging
Usually, if you end up out flying for enterprise or recreation, you might be utilizing three totally different energy sources. Naturally, everybody is aware of in regards to the plane battery and also you normally bear in mind the RC battery, however many neglect your pill, iPad, or telephone energy ranges.
Though the consumer handbook says that you would be able to count on half-hour of flight outing of the drone batteries, that’s extremely depending on a number of circumstances. To be protected, I normally calculate that every battery will give me 20 minutes of flight time if totally charged at take-off.
Vertical and horizontal speeds can draw closely and the facility ranges. Head- or tailwinds can change how rapidly batteries decline. Happily, DJI has performed an excellent job of together with a large quantity of battery information proper on the RC display so to preserve monitor of the scenario.
There are additionally a number of security protocols in place in case you lose monitor of the facility ranges. You’ll be able to set the alert limits inside the menu however I usually use the 20% degree as my warning and 10% as my auto Return To Residence setting.
When the battery reaches the purpose that there’s solely 20% energy left, an automatic warning prompts, indicating the extent. On the 10% degree, the drone will routinely start to land.
One other security characteristic prompts when the plane calculates that there’s simply sufficient energy to Return to Residence. To make sure that I can full virtually any mission, I carry seven batteries in my package.
The RC battery lasts longer than the plane batteries by an extended shot, however it’s not doable to slide in a charged battery as soon as the RC will get low. As well as, when your display gadget is plugged into the RC, the RC battery will switch energy to the display. This drains the RC a bit quicker and I’ve not discovered a way to close that choice off.
Moreover, don’t let the RC battery get beneath one bar of energy. If the RC battery will get too low, an inner sensor is not going to help you recharge the battery totally. I can let you know from private expertise that simply putting in a brand new battery is not going to remedy the issue. A complete new RC unit will likely be wanted.
Because the RC unit will use energy to cost no matter display you utilize, make sure that your display is totally charged earlier than leaving your private home or workplace for a mission. iPad, pill, and telephone chargers are frequent and when plugged into your automobile’s 12-volt system, cost fairly rapidly.
Nevertheless, there are solely two charging equipment accessible for the plane and RC batteries. Probably the most generally used is the house charger that plugs into your 110 volt house system.
Many firms additionally make a rack that holds three drone batteries however solely expenses one RC. I’ve learn a warning that recommends that you simply not cost the RC on the identical time you might be charging the drone batteries.
The opposite gadget accessible is the automotive charger. Nevertheless, it is vitally, very gradual. When I’m within the subject, I can not rely on even one battery charging to 100% earlier than I’ve used all 7 of my batteries. This all has to do with amperage, voltage, and plenty of different digital settings, however suffice to say that you shouldn’t depend on the automotive charger to maintain your drone going for very lengthy.
I hope I’ve been in a position to enlighten the brand new Phantom 4 Professional V2 consumer on some points with the drone. Every of those matters is a programming problem and I don’t know if there may be something that anyone of us can do to resolve them, however we at all times are shifting ahead with having fun with our flying.
Passion or skilled, droning is nice and the chances are limitless. Don’t make the error of considering I don’t like DJI or my Phantom 4 Professional V2. I solely purchase DJI proper now and till one thing of equal worth and know-how comes alongside, I’ll preserve my fleet.
