it's a very interesting product but I have few demands on it:
You say that you crashed it 20 times, is it because you don't know how to pilot this or because it's uncontrolable?
The replacement part in the video: are they new ones or are they the same that just pumped out in the crash ?
WHat kind of frequency is the Rx? 35/40/72 MHz or 2.4Ghz?
For the GPS part: is it an additionnal card or an upgrad of the firmware ?
Is there a software and a cable to manage it accuratly ?
Which kind of propellers are on the brushless?
Thanks a lot for your answers
