The antennas on those receivers are longer and that's probably what people are talking about.
I'm not sure what the isue is, but the first Spectrum radios had problems with the fuselage blocking the signal from the receiver in airplanes, hence DSM2...hasn't happened to me in any model air or surface but I figure why take the chance.
Unless it's carbon/kevlar it'll be fine. Spektrum makes special receivers for carbon fuselage planes that have really long whisker like antenna so they can stick out of the fuselage.
In a fiberglass, wood or plastic boat you'll be fine with the antenna inside only.
