Hi Bill @Groundhog
Alex's @unmannedtech advice re. Pixhawk is solid as the Pixhawk is an extremely capable system BUT IMHO do not write off the DJI Naza system...
1, The upgrade to V2 v4.02 does still work, if you cannot find the update software (it's still posted in various places) PM me and I can send it to you.
2, The Naza is much easier to set-up and will fly almost anything with the default settings. It was my first controller on a 560mm quad and as a newbie then I was glad of this choice. My own stupidity sent it well out of sight, I had no FPV then but the RTH brought it back from god knows where and landed it at my feet
3, The Pixhawk / APM is much more configurable, has the capability of autonoumus flight, will run from a ground station. It's very very good but not for the total newbie who just wants to get flying in the air.
This is just my observations, make your own decisions
