Just bought a JJRC X5 Epic. I can get 2.4ghz remote control range of 500 meters, but the 2K 5.8ghz camera only gives me about 180 meters. As this is a brand new drone I don't want to do any invasive mod. I would like to increase the fpv range externally. The cellphone I'm using to receive is a 5ghz wifi HTC 10. Anybody out there have any suggestions?
