Beautiful Miniheli with small defects

I fly for over 25 years with model helicopters, am not a novice but also not a professional in this field. Basically, there are on this beautiful little Heli not much to complain about when you factored in the relatively low price. The drive of the rotor is a rather wobbly affair and therefore precise flying is almost impossible. But when the price is hardly to be expected. Even through the slightly heavier and therefore more sluggish than with a coaxial rotor helicopter to respond to changes in speed for the high / low control bit slower and you have foresighted Fly habituation thing. The battery change is not as simple as desired and needed again some fumbling with the cable connector. The flight time of just over seven minutes is enough, in my opinion completely out, then you need anyway again a little break to catch your breath, because quite as simple as a self-stabilizing Coax Heli he does not fly itself. The attached transmitter I'm not quite satisfied, there are only two control modes for the joystick to adjust. Since I am / usual HOCHTIEF other way around, I had the potentiometer transmitter rewire order to deal with it. For newer generations pilot probably no problem flying anyway usually different. Another adjustment possibility would be desirable.
The flight performance and especially the body of the helicopter like it very much and looks very realistic. He also makes a stand model cuts a fine figure.
