This small quadricopter is really amazing. Nervous relatively stable (mine tends to drift a little) and terribly strong. After some interior trials, I tried it out (in Paris) is really excellent, but be careful not to get carried (remote control door to several tens of meters). He took a school wall, a grid ... But with a little effort we manage to control the well. By cons think about buying additional propellers (there were 4 provided with replacement, but after a weekend ...). Protection is a mild interest (it protects the propellers, but they tend to jump more easily). Additional batteries increases the fun for longer. Otherwise delivery from Hong Kong by PostNL (Dutch post), it took some time (2-3 weeks) but I had put my address Cityssimo by mistake, all went well.
