I think it is fantastic that PowerBox is offering the Atom system.
This will provide another option to those pilots not needing all the specs of the Core. It seems silly this is even being discussed by price ponit: Go buy a $400 radio. The discussion should be by the features being offered and what you need. Of course if you can afford this amount money for your hobby.
The way I look at my radio system:::: this is the heart of your hobby and controls all of your projects big and small. I look for the safety, reliability and features being offered. I am not going to fly a 10K jet with a $400 radio made to a cheapest price point
