No.  This equipment goes through rigorous tests both in labs and as installed
in each model aircraft to ensure that no EMI/RFI exists.

Very doubtfull.  There is just to many types of "toys" and to many differences
between aircraft.  Just because something may be a problem in one aircraft does
not mean it will cause problems in another.  That is why avionics/equipment
installed on aircraft are approved on a model by model basis.
