The Hubsan X4 came good today and securely packaged to contain with this spare rotor blades were with a lifting fork to detach the propeller, a USB charger, the battery, and the transmitter! A rotor protection is also included! The flight behavior is really great, he is really very quiet in the air after calibration and trim. The engines of the X4 are really loud and have power, and the complete housing is also heavier than the Revell QG550! The camera is quite ok, the videos are not as the bringer but it's enough to have fun! So in all I think this class X4, and I think I'll buy me in the foreseeable future the X4 in FPV!
In the shipping you have to be patient a little because the part of HK is supplied about 21 days!
