I have the Zoopa 150 now almost daily saying for about three weeks in operation and needs that I have been pleasantly surprised by the flight characteristics of this little. Although he reacts absolutely sensitive to every little breeze (even if it is generated by its own rotors), but otherwise it is so stable in the air, as one could wish. He is also surprisingly stable; a few minor scrapes on up to the rotors I could "crash" still reported no break despite numerous. You just have to pay attention to timely take off the gas, then no load is more on the components and the flyweight plays his trump card. If all else should tear the packaging is even a set of spare rotor blades; very exemplary! The processing and material quality of the helicopter is extremely good and is therefore in stark contrast to the supplied remote control, which you look at their Chinese origin in all respects and therefore you prefer to handle when wearing gloves. The built-LiPo battery of the helicopter is good for 5 to 6 minutes flight time. After that you should set to cool off briefly before it recharges. It is recommended only to order the optionally available USB charging cable same, otherwise the batteries of a charging station to use remote ends are quickly empty. Since I currently write much on the PC, I use the Zoopa for small diversion between. He's really great next to the computer and who else already has a USB helicopter? ;-) To summarize: I highly recommend the full Zoopa 150 each, even beginners in the field. He is worth every penny!
