This is my first helicopter, I was a complete novice in this field. A helicopter with double rotor came for me never in question. I wanted the same demanding variant. Despite that I was a beginner, and I came I get on well with the Heli. Ok, the first start / flight / and landing attempts were not glorious. But after a few cautious short siphoning off the ground as well as soft landings, I understood always better to deal with the flight characteristics. In complete calm, it is even possible to let the helicopter are in the air. Trimming was not necessary in advance. By my standards it is well adjusted.
The quality is really good. Many metal parts and (high) plastic let the helicopter appear dibasic. Several, partly evil Crashes that ran without prejudice, speak for durability. Only hard impacts on edges, such as curbs, can cause damage. I had once the landing gear after a crash on an edge, replace the rotor, the red metal disk is broken me out of the rotor holder, after I slipped against a curb and after a fall on a lawn rotor adopted. He got caught in the blades of grass.
Apart from these flight failures that still like happen to me sometimes, be flying with this helicopter can be learned very quickly and it makes a hell of fun. To avoid a possible shoot out the battery, I have fixed him with a rubber band. This can happen at hard landings before
Does the battery if you are not flying at full throttle, even almost 15 minutes and is recharged after about 2.5 to 3 hours. The problem with LiPo batteries is that they are quite suddenly empty and without much lead time. This can cause the helicopter pops sometimes from a few meters up unexpectedly on the floor. For me he has survived it always safe and without prejudice to now. Since I am but become very cautious and pay attention to the first signs of how lower riser height or cumbersome lifted off the ground.
If I were still better versed with this matter, I will also make changes to the settings on the remote control and try a little bit. To equal losfliegen, is the helicopter, well adjusted to my mind, so that actually only once not great much needs to be adjusted.
From me an absolute buy recommendation! Flying fun is guaranteed!
