This very large quadcopter includes variable pitch rotor blades! This gives it an ability for quick negative thrust on its blades if desired, which means this big boy can also fly upside down in inverted flight. Includes full 3D manual mode for barrel rolls and loops too! You can find it here https://goo.gl/CcLZ8n
