Included in the set are eight AA batteries, which you insert into the IR remote control. And a charging cable through this is located on the remote control (ie via the above batteries) are then directly charges the battery of the helicopter.
After 30-40 minutes, the green charging light goes off on the remote and you can for the first time starting the engines.
Note:
One small thing is not clear from the otherwise adequate operating instructions. After you have turned on Remote Control and helicopters, at first only the red cockpit lighting of the helicopter lights but the rotor does not start. Solution: Once briefly push the throttle and even the numerous position lamps and small luminaires in addition is ready to start - tips off by the push button on the remote control directly LUMINARIAS again brings more flight time / -fun.
As might be expected from Revell increases the helicopter, once you gently pushes the throttle forward, bravely and without eggs in the air. The initial rotation around its own axis is normal and can be turned off by means of the trim on the remote control child's play.
And then it says, from the reconnaissance flight by its own apartment.
Admittedly, quite so easy it is not. For me as an absolute beginner RC Helicopter is relatively tricky to control the helicopter accidents and unerringly through the apartment. But after a few battery charges (flight time about 8 minutes) are significant progress recognizable. So just be patient, dear fellow aviators. And if it calms: the good part is already several times unceremoniously on the floor, on the wall, in carelessly standing around houseplants and to nosy neighbor's cat crashed - but damage did not materialize so far. And for the worst case are included with the package replacement blades.
Conclusion: not a toy but a great employment for older young at heart without any experience on the terrain.
