I have noticed that some of the newest receiver designs put part of the circuitry in a metal can for shielding. I always wanted to try this when I built radios (R/C). This mesh probably accomplishes somewhat the same thing. It doesn't mean you can you violate the rules of staying away from the fuel pump and ECU(FADEC) with antenna and wires internal to the model.

Possibly the shielding protects from some lower frequency interference sources. Of course this is speculation on my part with out hands on tests.
