I'm currently looking at buying a F550. I like to build stuff and I already have a Phantom 2 w/H3-2D gimbal. Is there a reason why you guys/gals bought the F550? I'm wondering if I should be leaning towards a different build. I'm trying to keep my costs down so a Spreading Wings build is out of the question. I see the DJI Flame Wheel F550 with Naza-M V2, GPS, and Landing Gear on a few websites for $549. I know I'll also need a transmitter and receiver as well as a battery. I will probably opt for something other than the DJI DT7. Any suggestions on build items or insight would be appreciated!
