My first EasyStar RC flights- with GPS too!

Posted on November 23, 2008 at 11:32pm 4 Comments

Like many others, I have been mildly obsessed with the thought of building my own autonomous aircraft for some time now, and DIY Drones has been a wonderful inspiration. It helped convince me to purchase an EasyStar a year ago, but due to other activities in my life, it sat collecting dust in its box until 2 weeks ago when I finally began to assemble it.

Pat...I was reading a post of yours from a few months ago about someone who modified a DJI Phantom to use an APM as the flight controller.

I just wanted to say that your story sounds VERY much like mine...sank money into 3DR products, built an F550...put it all together, and then could never really get it to fly nice...tried and tried and tried, crashed and crashed.

So I sold it all and bought a DJI Phantom (when the price dropped to $479).  It's small and a bit limited in weight carrying capability...but right out of the box...FLIES GREAT.

I miss the APM sometimes for the potential it has for autonomous flight, data gathering, etc, but man, the Phantom JUST WORKS.

It just works.

I have been very happy with my decision to switch to a Phantom.

Now...that said...the heart of the Phantom is the Naza flight it may very well be possible to replace your APM with a NAZA, and be much better off that way. is very nice to have a pre-built, tested multi-rotor that just works right out of the box...and that it the Phantom (there are a couple other competitors now).
