We bought the Cloud Jumper for our son for 6 year anniversary. He already has experience with an indoor coaxial helicopter and thanks to the cage can not happen so much here. In contrast to the Heli Quadrocopter has another dimension, not just front / rear, up / down and rotate, but also fly sideways. This is of course a challenge and so he often crashes into walls or the ceiling. But he did take the start and along the wall quickly and skillfully the copter is absolutely inherently stable in the air. As long as there is no draft, it remains in place. The speed mode is really for professionals and here the Cloud Jumper does not have before other quadrocopters of Blade and Co. hiding: he is incredibly fast and is very agile.
