DJI Phantom Christmas? Awesome! Now READ THIS!

I posted this last year…but there’s still a lot of good information in there and so I thought I would post again. I have learned a HUGE amount since the original post so please feel free to comment if you have questions that you would like answered.

Houldsworth's Random Ramblings

fc40If you received a DJI Phantom for Christmas, then you are a lucky man…or woman, but I’m betting you’re a man.  

The Phantom’s are amazing machines.  They are great fun, produce really cool video footage and are super easy to fly as long as you have a good GPS signal.

But, before you fly, there are a few things you need to do, and a few things you need to know.  

Not following this advice is, in the opinion of many, the #1 cause of “flyaways”, which is when the thing takes off and is never seen again.  This is usually followed by people blasting DJI on Facebook and then deleting their post when people ask them about home lock.

Most of the details below are from my experience with an FC40.  You may be lucky enough to have a more advanced unit, but the information should be mostly the same.

Drones: One year on

On January 2nd this year I took a flight over my neighbors house using a store bought drone (Phantom FC40) and a GoPro camera that arrived as a Christmas present.  I was very happy with the quadcopter and the footage I took.  Then, about a week later, I sunk the whole kit into a lake never to be seen again.

At the time I was pretty upset with myself – I made a rookie mistake and paid for it badly.  But I also reasoned that since I had enjoyed modifying the FC40 I should try my hand at building drones instead of buying them.

One year later and I’ve come a long way learning everything from soldering to PID tuning (don’t ask).

I eventually built two different copters, a quadcopter and then a hexacopter, although it feels much more than that because each of those has been built, rebuilt and upgraded numerous times.  Here’s a quick comparison:

 

DJI Phantom FC40 F450 Quadcopter F550 Hexacopter

Transmitter Range  800m 2,000m
 Flight Modes
  • GPS Hold
  • Altitude Hold
  • RTL
  •  GPS Hold (slow and fast)
  • Altitude hold
  • RTL
  • Automatic (programmed)
  • Land
  • Guided (click on moving map)
  • Manual
  • Acrobatic
  • Follow me
  • Circle
  • Mapping
Speed 22mph ~35mph ~55mph
Size 330mm 450mm 550mm
Real Time Telemetry No Yes Yes
Moving map No Yes Yes
Gimbal 2D 2D 3D
Camera Control Manual Manual or Fully Automated Point Of Interest Lock
Flight Time 9 Minutes 18 Minutes 15 Minutes

 

But probably the best way to show the difference is to compare two videos taken one year apart.  The video on the bottom was from a year ago with the Phantom. It took two separate 9 minutes flights and was then edited to keep only the best parts.  The video on the top was taken in one shot, no editing and took less than 3 minutes to complete from take off to the fully automatic landing.

In fact this year’s video even made it into the local news, and you can find the full version here.

I’ve learned a huge amount that past year, gained some great friends and had a blast doing this, particularly as my #1 son and daughter were very involved in the build of both machines.

Where do we go from here?  

The drone market is in a phase now where digital cameras were 10 years ago.  Their capabilities are increasing exponentially while prices are plummeting.  Even with how far I have come even the cheapest DJI Phantom 3 would outperform my hex in almost every way and these can now be had starting at under $700.  Just a year ago something with that capability would have cost nearly three times that amount!

For me to build the equivalent of a Phantom 3 Standard would cost around $450 in parts alone, and that is if I use cheap parts sourced from China that would need a lot of time to set up properly.  

Will I still build?  I think the days of building from scratch are over, it just doesn’t make economic sense anymore.  But I will continue to improve the ones I have as a way to learn and experiment.  There’s also talk of teaching kids how to build them as part of a maker space project and that is something I would really enjoy doing.

In the meantime, if you are thinking of getting someone a drone for Christmas, or have one and need questions answered…fire away!
