The current wisdom seems to be to "ground everything" which I am in the process of doing. BUT... All the ham gurus recommend using tinned braided wire for RF grounding in preference to the usual copper w/ insulation "hook-up" wire. I can't figure out why this would matter. And then, of course, the real meat of the matter... If I do this to my SkyRanger, will it decrease RFI through my VHF Comm???

I'm not sure what they are talking about re: tinned braided vs copper, but it sounds like nonsense to me. Unless you're dealing with high power levels and very tiny hookup wire, the RF is going to get grounded either way. RF travels down the circumference of wire, so larger diameters are better - to a point. You won't notice the difference. Your VHF comm radio should already have good shielding, so going crazy with grounds is not necessary. A single ground should suffice. What RFI are you trying to eliminate?
