Do you think I should contact the retailer or Spektrum directly..??

Have there been any solid reports on such problems?? I think i read a test article for the M11 with Spektrum Pro a few months ago in a magazine and it said something about an old version which caused a few delays. I think It also said that Spektrum fixed the problem on all their newer versions of the Spektrum Pro Systems.. I'll try to dig out the magazine and post the article or a link to it if it's still available.
