RE: Which Radio?
DadsToysBG is right about getting what you will want in the foreseeable future IF you can afford it. In the past my 7U has done all I have asked of it with the exception of a couple of things I have been able to work around. The 7C 2.4 will do more and keep me happy for quite some time to come. The 6EX 2.4 fell short of what I wanted.
