The load is very long 45 minutes but for this it necessary to recharge the USB adapter will not work because it is simply impossible to connect it to a USB port (very very low quality adapter).
I used a phone adapter to recharge it ... like about 5 to 6 minutes maximum wide and difficulties are enormous for the master to the ground for the flight is almost impossible even using the trim on the remote .
The application must be downloaded to the Apple store to call "Helipad" ergonomics and grip options are simply another age, I do not understand how it is possible to get such a product, of course I'll spare you the use of a target or the battle mode with another camera that is simply impossible.
It is possible to activate the sound effects (this part works) with the remote control, it is the sole reason for satisfaction of this device.
For nothing
Against: uncontrollable, HS USB cable ... the list is long!
Conclusion: This is an expensive gadget that will not make everyone happy ...
