This is a pack of two optional DJI E300 Self Tightening Propeller, in Gray color. This package includes one CW and one CCW E300 blade, as part of the E300 Tuned Propulsion System from DJI.
Representing the state of the art in this industry, the 9.4x4.3" rotor offers an approx. 20% ~ 25% improvement over the 8.0x4.5” rotor without the need of using a heavier motor, making the 350 ~ 450 model quad copter achieve a significantly higher lift and thus more powerful to carry a camera and gimbal setup (FPV). The rotors are carefully balanced dynamically, you will never be bothered by jello effect from your airborne rolling shutter camera. The low inertial design enables your flight controller to use a much higher gain value to achieve a higher stability and maneuverability all at once.
Diameter/Thread Pitch: 24x11cm (9.4x4.3")
