[NSRCA-discussion] Futaba and pattern

[Ron Van Putte]

I'm probably going to step on some toes, but it could be that Futaba  
is reluctant to admit when problems occur, because it would cause  
them to "lose face".  I don't understand all the reasons regarding  
why Futaba might act this way.  Maybe someone who is more  
knowledgeable on my stereotyping of "orientals" can straighten me out.
