i have the syma x5sc, been practicing a lot over the last few days and i have started to take the quadcopter higher now, i can get it to about as high as a normal house at a nice hover, then if i take it a bit more higher it starts to wobble and drops fast. i can get control back so it does not crash into the ground when its about 10 meters high. just wondered what would happen when its out of range.
