Original DJI E305 Propulsion System Kit 4pcs CW/CCW Motors & 4pcs ESC & 3 Pair of Propellers for Multicopter Weighing 2.2-5.5 Pounds (1-2.5 kg)

Finely customized and painstakingly engineered, the E305 Tuned Propulsion System is specifically designed for multirotor copters weighing 2.2-5.5 pounds (1-2.5 kg). Combining increases in efficiency with proven, classic components, the E305 system provides maneuverability, stability, and efficiency in a highly cost-effective package.





Features:
Built with improved manufacturing techniques, the brand new 2312E motor represents a significant upgrade over the previous 2312 model. The optimized electro-magnetic system boosts efficiency by nearly 7% and lowers cogging torque, which provides noticeably smoother performance at low RPMs.
A newly designed motor base not only provides better heat dissipation, but also a more advanced, hi-tech look.
The 420 LITE ESC utilizes the tried and tested square-wave drive architecture, further perfected by DJI engineers.  
The 420 LITE provides simplified functions in a much smaller and lighter package than the E310.
Internally, an efficient and responsive algorithm is hard at work to provide your platform with a level of maneuverability and stability that belies its size.
Aerodynamically optimized and precisely manufactured, the Z-Blade 9450 propellers produce powerful thrust with excellent dynamic balance.
These reliable blades easily handle your FPV and other payloads while keeping your platform stable and virtually vibration-free, helping reduce the chance of jello or other unwanted effects.
