I have had my Standard for a couple of months now and because of winter, have just been able to take it out to test it's range. I am pointing remote correctly, withfully updated firmware(1.5.70) and app(2.72), and after four hours of flying in a variety of places including out in the country, my best range is 447 meters. Usually it is between 50 and 150 m before RTH is set off. I checked DJI site when I decided to purchase this and they claim up to 1000 k. Is there a problem with my machine? I have an Argtek extender unit but I don't want to disturb even the glue on the rc antenna wires before I find if this is normal in case it voids the warranty. This doesn't seem normal to me when I see many others getting one or two km even with stock antenna. Is this a problem that I should be creating a ticket with DJI for or is it just the luck of the draw? I am in Canada so I assume my rc is fcc. How does one tell if it is using fcc or ce? Also, one last question. Does anyone know what the small hole with an x beside it on the back of the remote is for? It is not mentioned in the online Manuel.
