DJI Naza-M V2 Flight Controller with GPS - Latest Version 2.0 All-in-One Design for Drone, Quadcopter & RC Aircraft | Perfect for Aerial Photography, FPV Racing & Professional UAV Applications

'The' most stable, predictable, accurate and easy to set up quad flight controller EVER! I also bought the iOSD to compliment the system and now maintaining orientation and monitoring flight parameters are extremely easy and straight-forward making my F450 very safe to operate with a high degree of confidence. I've used several other 'popular' flight controllers (which arrived with a paucity of documentation or instruction) which required countless hours of tweaking, watching volumes of YouTube videos and 'repairing' which, unfortunately, only resulted in frustration and never produced a machine that was predictable and a pleasure to fly!! Given those experiences, I was a bit hesitant to spend the money on the DJI Naza-M V2 system but I am extremely glad I did!! Flying is FUN now and I look forward to each and every flight!!The only downside is the expense, but if you weigh the cost of your time & frustration (not to mention the expense and time required to repair damages) with VERY little to show for your efforts against the cost of the DJI controller, it's well worth the money!!
