Has now been hintersich several flights and crash landings and still heal. A battery is becoming empty one can easily notice the sinking climb performance, one must always give more gas to keep him on the spot, so do not worry that it stops suddenly and crashes. Also very nice is the included USB charging cable in order to protect the transmitter batteries. If the red lamp in the USB plug is out, the battery is full. Unfortunately is not in the manual. In the packing a second connection clamp between gyro and upper rotor is that needs to be fitted beforehand. In addition, 2 spare propellers for the tail rotor. Spare parts if you need for what you get also here at Amazon. So, no Angts if something breaks, you do not get the spare parts. And got him out already flown with no wind. Also makes no problems. Only the rotation is somewhat hakelig with fully charged battery, after a while it can be soft but dosing. The climb, Sinkbewegungen can be controlled, which can be a hover just above the ground at a fun very soft.
+ Long flight time
+ USB charging cable while
+ Super stable
+ Control very soft
- Turn slightly hakelig
All in all, an investment brings a lot of fun.
