Electrical noise is unlikely to happen from a moving wire, otherwise each  
wire inside any device would be a hazard.
When you move it like in a magnetic field things are totally different.  
Also, the moving parts in RC craft do seem to cause some strange sort of  
interference i do not understand (especially helicopters it seems).
