Hello, I'm new to the forumns, it's a really nice place! Anyways, i have a P3S, and i have installed the argtek mod for extended range, but it has made the range worse. I reverted to the stock antenna, but the range is still bad. I cant get out more than 370 ft away from the controller without the video crapping out. No matter which antenna i use. I might have damaged the board inside the TX when i have installed the mod, not sure what to do. If i need to get a new controller, is there a possiblity to use the 4k controller on the P3S? They both use wifi, so i was wondering if it's a possiblity.
