OK, I was waiting for this one - always happens eventually when the personal attacks begin simply because I made a decision that someone else may not have. Further, I beg to differ strongly about this hobby "not being for me" just because I returned a defective unit. I have owned and flown more than 250 RC aircraft over a 30 year span including large scale helis, 3D airplanes, sailplanes, float planes, gyro-copters, ultra-lites, and dozens of aircraft of my own design and engineering. Besides, this is like saying "driving may not be for you" because I returned a brand new truck that had some potentially serious problems or simply didn't work as advertised.
I expect that something as expensive as this Phantom should work out of the box and get very nervous if it doesn't. As mentioned, I've flown RC for 30 years now and do a LOT of my own repairs and mods galore, but when it comes to a system that basically has a mind of it's own and could cause some serious issues (property and otherwise) should the electronics not be up to the task or poorly constructed, the responsible and smart thing is to make sure that it arrives 100% functional as designed or return it. Lemons DO exist in every product line - even quality products that DJI is synonymous with. Having said that, cables, etc. do come loose during shipping and that is something I am OK with and of course fix myself but this was not the case with my Phantom - everything was tight and snug. The micro electronics were the issue.
Also, if something as basic as the VU board is bad, or even a simple 4" USB cable what else may come up or be pre-existing. My experience with electronics is that one thing being wrong is usually not the only thing wrong because Quality Control would have caught any problem unless it was passed over entirely for whatever reason or assembled by the second string team. People assemble these things and people are imperfect and have 'off days' like we all do. I don't need this thing flying away because I may have received a lemon, or worse - falling out of the sky and crashing on someones Mercedes or God forbid, some kid a mile away. I've had a 5 meter sailplane go south on me for a time when 1200 ft. up, but it at least it stayed in the air long enough to regain control when the problem was resolved (transmitter antenna issue). However, the glide path is particularly bad on a quad copter should the electronics 'check out' - I play it safe, always have.
