I always wanted to fly a remote controlled helicopter, but as a child (now the 30 years ago) were my Dinger too expensive, and everything I had lately, was no good really (eg the little things of Silverlit or a banana helicopter). I also had a "right" Single-rotor helicopter that was so difficult to control that I have this frustration resold. After some time of abstinence I found on the Internet on a video with this MJX helicopter of type F-645th It looked really great, and the price of a single-rotor helicopter with Gyroscope and 2.4GHz remote control was so hot that I had it 'chances. When unpacking the helicopter made a good impression: he already brings some weight on the scale (which is good for outdoor flights with little wind), and two servos that drive the swash plate can include a good controllability. After charging the battery, it went along with my son (7 years old) on our sports court - and then it started: After a few minutes the steering commands are internalized, and then it makes just more fun. Thanks to the sophisticated gyroscope of Heli is quiet in the air, so calm that I (with backlit LCD screen for setting all functions) let Sohnemann to the great remote control. Lo and behold, after a few minutes the little one has flown the thing like a pro. He still knows how even a Punktandung the penalty spot of the sports field. Fortunately, I had the same ordered a replacement battery, because the approximately 7 - 8 minutes flying time something is scarce for two pilots. My son and I are absolutely thrilled - let's see if I can still buy a second MJX F-645 for my son for Christmas.
