Charging via the USB port is functioning properly and is essential Low power consumption than the usual shop on the remote control.
The initial flight tests have failed miserably and the Heli has had some crashes, therefore fragile or sentimental belongings should first banish from the flight zone :)
Robust Heli is always even drops from 3m height have damaged anything.
Only the rotor blades got some quirks, but not really dramatic.
The supplied spare rotor blades will certainly come in the future but as a useful :).
The start I find persönlcih somewhat difficult because the helicopter is not very well balanced and the tail when you start back flips.
Thus, the helicopter has to start when you start the urge towards the tail, here you have to be an appropriate response, which with a bit of practice but is no longer a problem.
Who still has problems may start out of his hand, which is much easier.
Once he is in the air it flies perfectly and stable.
The control works smoothly and also readjust if the helicopter something in the air "turns".
The sense of control must however find itself each.
Thanks to the switchable LED above the left wheel on the remote control Night flights are possible.
An estimated flight time depending on how energy efficient you are flying from 7 - 10 mins, which corresponds to the average.
One should however be careful when flying at least the windows are closed as the helicopter but is quite susceptible to flow due to the small size / weight.
All in all a robust entry-level model. If the heli a bit better balanced in the state would be the 5 stars and nothing in the way, so there are "only" 4
