I don't see how Flysky signing pros is any different than Sanwa, Futaba, Spektrum...

The other thing people forget is that signing pros is supposed to be a net profitable investment (i.e. ROI is positive) -- i.e. drive up sales because everyone says "ooh, XYZ is winning races with that radio, it must be good", and then everyone starts buying the radio. More sales means higher volume which is supposed to already pay for their investment.

I do see a lot more interest in these radios since big-name pros are running them. Personally I don't think the street price of the NB4+ will be any more than $30 than the previous version, and I would argue the improvements they made are worth that. The screen really is way better than the old one.

And yes, I paid full retail for mine.
