You just blew my mind, I didn't know HB made a smaller unit then the 700 series. It looks like they just limited the 700 series down to no networking and no ipilot and called it a 500 unit. That seems a bit "scary" to me. Why is there a 798 and 598 when the units are the exact same size? That is a slap in face from HB, I'd pay the 200 more and get networking.
