Bests & Worsts Reviews from Amazon

My first foray into multi-rotor flight. I picked this up as a starter set based on advice from a local users group that learning to fly is best done before investing in a copter that does all the work for you by relying on gps and altitude locks. You will need to actively fly the UDI U818A. It's stable in flight, but easily pushed around by the lightest breeze. It doesn't hold a specific location or altitude on its own. It worked right out of the box as soon as I had charged the flight battery. Be warned that there is plenty of power to send this flying quickly out of your control range, which will then cause it to loose synch and flutter lightly back to the ground (or tree top). The only damage mine has incurred is the occasional displacement of a prop shaft that needs to be pressed back into place to fully mesh the offset gearing. The on-remote trim switches can be used to dynamically adjust the stability of the quadcopter. You can zero out any slight side slipping or rotation by tweaking the three trim switches this way or that. Once that's done, the copter will park itself quietly over a single location until the next change of wind or joystick input disturbs it. The onboard video and picture snaps are not high definition, but they are static free and very stable when loitering at altitude. You won't know what you've captured in the camera until you get it back to your computer to transfer the files from the camera via the included USB cable. For those who might prefer an FPV setup, there is an upgraded model of this quadcopter on the market that swaps out the onboard storing video camera with a broadcasting camera that your wifi equipped smart phone can receive video from.
