I have laid the quadricopter for my 7 year old son, but neither he nor I manage to control even remotely controls the quadricopter. Previously, we had a 20 Euro helicopter (not quad!) From the supermarket and even the could better control and trim. A real difference between the two settings Mode 1 and 2, I also could not tell. Also described in another review problem that not the connection of the remote control can still be hergstellt the quadricopter, we were able to understand enough. The 1 star is too much.
