Guys, I'm going to want to upgrade transmitters soon or eventually into the future. For reliability, protection and safety, and peace of mind. I know people use brands like Futaba and Spektrum. My questions are these: 1. I can upgrade / replace the transmitter for my 5.8Ghz Phantom 2 Vision +, correct? I know this is possible with the 2.4Ghz Phantom 2. 2. What is the recommendation for a quality industry transmitter at a good price? I do not think I want $800 or higher controller for a quad that costs about $1k. I'd like to stay at $300-400, have better protection against radio interference, but not absolutely break the bank. Cheers! Thanks!!
