The did not want to far, far away

I will not go into the positive characteristics here that are already sufficiently described in the other reviews, but explain why I forgive only two stars.
At first I noticed nothing yet and was very fond of the copter. However, after some time I wanted the moderate set limits Flight height advantage 100m and 300m radius.
But even from a height of 80m and a distance of 160m, there was always disconnections for Copter Copter and always came to GoHome mode, no matter how I've aligned the transmitting antenna for Copter. This coverage is far too low, and a safe is flying so impossible. I do not want to be reliant on the work must always failsafe.
I was about to send the aircraft back, but as an experienced model builder I noticed that the receiving antennas is not as usual, in 90 GR angle stand to one another. So the antennas oriented, and lo and behold, the limits are set Flight now no longer a problem. And thus also had the send back completed.
I can not understand why such a thing is delivered from the factory, the orientation of the receiving antennas is well known in the model and is required by the remote control manufacturers at transmission frequencies of 2.4 GHz, and here is even sparked at 5.8 GHz, which further exacerbates the whole. For me this is a lack in the factory and is safety-related, as the aircraft makes fast times independently when not working the failsafe. The Faisafe only works if enough GPS saddle Teten received 6 pieces. The set of mine Flight Limits H 100m 300m R are, in my view at most distances, we HobbiesModel pilots allowed to fly only on sight distance with us.
In the forums, the problem I have described is very often highly cooked so not an isolated case. I was able to deduce that some have simply turned up the transmission power, which is of course forbidden to us.
