Hi,

I just bought this little and fun spark

Currently set the band selection on auto, which most of the time is on 5.8Ghz. I did tried once using manual and opt for 2.4Ghz, but too many interference and bad signal lost

So how far the spark can go using the 5.8Ghz band ?

3 KM and above without any image transmission problems @ VLOS

please read specs of Your aircraft in it's manual (accualy read whole manual for safety - I guess You did not - bcse that data is pretty self-explaining):

Remote Controller
Operating Frequency        2.412-2.462 GHz; 5.745-5.825 GHz
Max Transmission Distance        2.412 - 2.462 GHz (unobstructed, free of interference)
FCC: 1.2 mi (2 km); CE: 0.3 mi (500 m)
SRRC: 0.3 mi (500 m); MIC: 0.3 mi (500 m)
5.745 - 5.825 GHz (unobstructed, free of interference)
FCC: 1.2 mi (2 km); CE: 0.18 mi (300 m)
SRRC: 0.7 mi (1.2 km); MIC: -

it's range depends on location You flying. and keep in mind it's MAX range in perfect condition... ussualy You will get way, way less....

Hi, there. I would recommend you fly in a recommended flight environment and choose the channel with best signal.  Please turn off the bluetooth devices around your spark. Do not shield the antenna of RC. Please keep us updated, thanks.

Thanks for all input

I guess 1km is good enough for this tiny drone

I'll do more fly time and see what's the best setup for the spark
