K3 has hit the nail on the head with that one as far as I'm concerned. I am willing to concede the fact that I don't know for sure that they are the same company, or under the same operations. I know, however, that the opposition will not concede that they do not know for sure that JR and Spektrum are NOT the same company.
The point is, there are many reasons why JR would want to conceal it's relationship (whatever that may be) with Spektrum, and K3 has said it better than I've been able to.
However, if JR were to put their name on a SS, 7 channel radio, it would be NO different from the "Spektrum" offering available now. Therefore, I rest assured that I'm using JR's equipment.
