The positives first ...
The battery will now load much faster. While it previously took yet between about 40 minutes (USB charging cable) and up to 60 min (batteries of the remote control), the charging process is complete after about 25 minutes. The Hubi thus depends less on the line and flies it often in the air.
The charger is reliable and indicates by the extinction of the red LED that the charging is completed.
IMPORTANT !!! The time to cool the battery pack (20 minutes) both after flying and after charging still must of course be adhered to if you do not want the battery fail prematurely.
And now for the negative part ...
At first I could not plug correctly the connector easily. He was much too loose and slipped constantly by itself out again. As I the whole thing looked at me more closely, I noticed that an edge having the plug of the charger to the point at which the end of the USB charging cable, a slope was (see "Figure 1 - Little difference" in the gallery).
This edge pushed against the board of Hubis and prevented the tightness (see "Figure 2 - plug is too loose" in the gallery).
So I just cut off that edge, so that both connectors were approximately the same shape (see "Figure 3 - The edge was ground" in the gallery).
And already fits the plug - sitting, wobbles and has air (see "Figure 4 - Now a tight fit is ensured" in the gallery).
The whole thing took less than five minutes and already I could charge the battery with the benefits listed above.
Despite these initial problems I forgive 5 stars because I just go out of it, that it is more likely is an isolated case, as to the rule. Finally, one can say bad, whether the fault really lay on its connector or whether perhaps simply was the charging socket on Hubi not exactly the right place.
For me, outweigh the benefits, and besides, I had no desire to sit still for such a small thing until the machinery of guarantee and conversion in transition.
