I just got one of the new Eflite UMX F27 FPV brushless flying wings. This thing is pretty quick and it's a hoot to fly! I dont have fpv goggles to try, so I just fly line of sight. It has SAFE with two self leveling flight modes which are great for learning, but make it difficult to fly in tight spaces. The agility mode has as3x but no self leveling. This is the fun mode. Launch in SAFE mode, then switch to agility mode. I set the rates in agility mode to 80% with 45% expo.
