I read and saw enough reviews about this quadric. Well, what can I say, I'm upset. It's too fast and sharp for the house, even with the remote control set to 20%. The screws just fall off. Pull the battery by the wire when you take it out. The charger connector is so tight that it pulled out several times along with the giblets. The design is ill-conceived, just everything. The remote control is huge, and AAA batteries. The remote control screen is without backlight. The quadric is too small for the street. I really havenβt tried it on the street yet. My opinion is that this thing is for an experienced flyer, but is it interesting for experienced ones?
