Hello Martin and James,

In this case was talking about Wi-Fi connection between smart-phone 
where runs DJI Go 4 app and the remote control radio, they remain close 
to one another all the time. But certainly the flight range of Spark is 
not as great as the one of the Phantom.

There is a list of compatible smart-phones for the Spark at the very 
bottom of this page: http://www.dji.com/spark/info#specs . I read at the 
DJI forum that if one uses such a smart-phone the range is better.

I flew Spark maximum about 700 meters away and 150 (legal limit for the 
region) meters high. The video & control signals was present all the 
time, though my old smart-phone is not in the list. I ordered already a 
compatible one.

For me this range is OK. The best aerial photos are made from the 
altitude of 70 - 100 meters anyway, and besides in accordance with the 
regulations it is allowed to fly only LoS (line-of-sight) anyway (unless 
there is a special license).

The Spark remote controller has got folding outside antennas, so the 
range of several hundred meters, or I would guess up to 1 - 1.2 km, is 
probably due to these antennas. The range of the Phantom is more than 2 km.

Best regards,
