The helicopter can be charged via the remote control. For this purpose, a charging cable is in the bottom of the remote control.
This remote control looks a bit cheap and the control lever too soft. Nevertheless, an accurate is thus possible to navigate.
Much better I find that charging via included charging cable with USB connector.
This USB power adapter power adapter I have are at home and invite so without the supplied remote control batteries to empty.
The Goshark is very light and strong. He has survived and spare parts are available from the manufacturer Panland Several clashes.
Designed for indoor, it can be wonderful to fly out even in cloudy sky. It just has to be calm because with every breath of wind, the helicopter is drifting out of reach of the remote control infrared device and then crashes.
