Quite nice, but not exactly brilliant

this drone is in my opinion not suitable for indoor use, as it is actually intended by the manufacturer.
For this purpose it is just too difficult to control, so more frustration, rather than lust arises.

This is mainly because the trim function not very accurate.
Floating freely without which it is drifting in a direction to me not very well done, no matter what "correction" I have made and yes I have read the operating instructions completely before and followed.

Outside it is also of limited use, because it is just too easy and therefore already comes the lightest wind into a tailspin and swings. The manufacturer recommended stopped the drone only with no wind and use absolutely dry weather.

On a positive note the exact manual (in English and German) as well as the successful remote control with illuminated LCD - Display. It is comfortable to hold and displays all relevant data and outputs signals for eg trim strength / LED on or off, etc. again.

The processing of the drone and remote control is not bad per se, and especially for the price. Just as already mentioned, the rotor blades are very susceptible to wear out quickly. However, this are 4 pieces to replace the drone in with. Another plus.

Whoever it is considering to install a camera to it, just believe me it must weigh no 17 grams. This model is designed only to dead load and is not at all well with additional weight.

The original battery (250 mAh) is very weak for the rest on the chest and takes a long time to load. Without LED and without much maneuvering flying the model with me 5 minutes. At most. Then it was over and suddenly!

Who flies high at the time the threat of total failure or fatal crash.

One can also have a larger battery 380 mAh (about 9 g net weight / Pries for 2 pieces approximately 9 - 10) get it. This will probably hold a bit longer (about 20 - 35% more, as you write in forums). I could not test this, however.

For me the Quadrocopter goes back again and I stay with my first Helicopter is to control very well in rooms, also a little longer flies and not have to load so long.
