hey guys. gotta question. im thinking about buying a seperate controller for my phantom 3 pro and doing a fpvlr mod to it. i hear the ones with the amplifiers are very directional. thats why i would like two controllers. one for long range in one direction and the other for average flying around. stupid question, can you use different controllers for a single aircraft or is it more of a pain then its worth? anyone else done this and have success? anybody have any suggestions of the best mod?
