Theres always gonna be something coming out soon thats maybe better or not, than what you have or intend to have so if now is your time for the Q4K then heres some facts for ya....
1) Range isnt as good as the phantom .. stock ..However my q500 4k hasnt lost video signal so far and ive been out till i almost cant see it anymore !!!
Their are range extenders for the q500 that triple the range and only about 125 bucks..if need be ..as far as disconnecting...the q500 WILL RTH if lost control signal and video feed usually reconnects when back in range. You can also re take control while in RTH at any time !!!
2)If your an experienced pilot then disabling the gps will make the q500 FAST....However , you must land and restart the Q500 for the GPS to be active again.
3)This Q500 is ,IMHO ,VERY easy to fly AND land
Out of the box,no update to do,charge batterys,install props,calibrate compass and accelerometer in the field (very easy),turn on st10+,turn on q500,fly, enjoy !! wont be sorry !!
Price wise, the bigger value is Yuneec by far....
