Received an NB4 over the weekend and started messing around with it. I don't have a lot to compare to as the last real radio I had was a Futaba 2ch crystal. This must be what my grandparents experienced seeing smartphones for the first time lol.

The transmitter was on FW ver 2.0.85 (I think...) and I updated to 2.093 FCC and then 2.0.100 FCC versions hoping I would bind a receiver after the .93 upgrade and not have to rebind but that was not the case. Had to put the receiver into force bind to get them to update after updating the Tx. Aside from the not so straightforward firmware updating this seems like a really great setup and easy to navigate/use.

I did have some confusion with the Assistant. The download is a .rar file and you need to use 7zip (or something else that can extract the contents) to get to the .exe to run it. That was a bit of a frustration as well but got it all up and running. Just ordered another FGr4S v2 for my B74.1D build. Looking forward to getting more stick (wheel?) time with this remote. Great feel in the hand.
