We were disapointed in this toy on Christmas morning. It was impossible to fly - it just went sideways as soon as it took off and nothing we did seemed to calibrate it sufficiently to hover. The instruction manual says "After charging the aircraft the light will flash for ten seconds. Turn on the aircraft and controller and wait for flashing lights to indicate the aircraft is ready for flight." What it fails to mention is that it is critical to place the "aircraft" on a flat surface at his time IMMEDIATELY after inserting the battery. The model then apparently is able to calibrate itself and will hover reasonably stablely. The online manual clued me in to our mistake (we were probably holding the model in our hands in an un-level position for the first dozen seconds after plugging in the battery) "When insert the charged battery, quad copter will into automatic detection state (the indicator light flashing swift in the first ten seconds when power on) at that time, please place it at a level position, if not copter will fly inclined" Plug in the battery, put it down right away on the floor or table top. This should be included in the printed instruction manual, the toy is worthless without this knowledge. But once you know the secret, it works quite well and I can recommend it.
