Has nothing to do with "affording" it. I cant think of one time anyone felt a software UPDATE was ever worth $400, when told your current product would be updated for free when updates are available.
Anyways, I have said my piece, and I agree HH has painted themselves into a corner on this one. Not just the DX18 is affected by this choice of exclusivity. Any future products cannot have those software features either. So this is, IMO, gonna come back to bite them.
I can only hope and "dream" that HH will figure out that they need to make a change on this software stance, in order to attain and retain the level at which they had attained with the Spektrum name for now and in the future. But that needs to be done now, and not after they have sold all 2000 units. They need to admit there was a mistake made in making software exclusive to one version of the DX18, when they are features that would sell either version, and features that any purchaser of the DX18 should have.
Do I still like and use my DX18? sure, but will I promote and look to Spektrum in the future? I am not so sure I will so quick to defend them now, with this, IMHO, a poor choice to hold the software from the current DX18 community.
Truly if anyone buying the DX18QQ bought it strictly based on the software, then I feel sorry for you, as those features should be a part of every DX18 and surely are not worth $400 extra. And if you did make the choice based on the software, you missed the point of the QQ version.
