2 purchased by Heli`s because the low price - First mistake !! Both charged batteries in and off you go into the remote control. And How !!!!! Do not let them set the record straight just circles around selbst.Egal how to adjust. Flight time is about 10 min. completely übertrieben.Keiner the two manages more than 5 minutes to keep in the air. Despite already several Ladezyklen.Bezugnehmend on the ability of the outdoor Heli`s I can not write about. Even in complete calm, it is not possible to HELI controlled at STEUERN.Infrarotsteuerung outdoors ?? Set your TV to the outside and try it with the remote control to bedienen.Keine sun, no wind and a maximum of 2m. Extremely difficult. I have already bought and tested 30 I / R Heli`s but is certainly one of the worst I've flown.
