Hi guys, enjoying my P4 more and more as I use it more frequently during the lockdown here in SA. Now with limited movement to curb the spread of the virus, my drone has become quite an attraction. So as I am becoming more confident with flying, so I Haber flying further and further of course. What I did however notice is that the range seems to max out at around 850m. Fully charged controller and battery. Any advice to improve range?
