The joy was huge from the start. I was totally surprised that he (a charge = Felt 7-8 minutes flight time) Sky Fun was able to maintain relatively stable already in the air after only two or three charging cycles to. The two flashing LEDs come with the children respond well to (especially at dusk). We have in relative calm even let him one time or another flying outdoors and it worked quite well. Of course, once something wind comes, it puts the flyweight immediately a bit and you have to counteract trouble.
After 15-20 recharges the small Brummer made no peep. I do not know if it was on the helicopter or on the remote control. Has been replaced by Amazon now straightforward. Since then, my son flies daily to the 10 charging cycles (10 x 8 min = 80 minutes flying time daily during the holidays should be enough ;-)) and maneuvered the helicopter now in the home effortlessly between obstacles through. Actually I was initially of the opinion that those helicopters have a very very short life. Granted my son pays attention to him very much, he is just currently the most beloved toys. As soon as he came into the vicinity of any items during its first flight tests, he put the throttle back immediately and thereby made an emergency landing to prevent damage to the rotor blades. So far only has a rotor blade a slight tear, because we have now reinforced with thin adhesive tape. A Reserveset is.
This nice part is not only very entertaining for children and trains the coordination. Also Papas fly very happy times with it. :-)
Addendum: Unfortunately, the battery capacity after about 60 charging cycles significantly. Despite adherence to the recommended 15 Min. Cooling phase of renewed charging. Loses now after only two to three minutes significant height. Fly after that for about two more minutes than 1.5 meters high. Must therefore unfortunately reduce the full score to four stars.
