MR Series Heavy Duty

28 poles brushless motor, specially designed for 
high-end multi-rotor and UAV systems.
Based on the mature TE-MR technology and 
all parts are newly designed 
2nd generation stator, using the best 0.2mm silicon material to improve motor efficiency
Lower IR winding to decrease the temperature 
remarkably when long-time working
Modular stator, easier to maintain 
Imported over-sized ball bearing, lower noise 
and ultra-long working life 
Short shaft designShort shaft design
High-precision rotor, dynamically balanced on both sides, lowest resonance in RC industry 
New stator cover to protect power wires 
Multiple mounting holes, compatible with DJI frames 
Lengthen silicon power wire, easy to install 
Laser-etching model data and factory serial number 
Comes with propeller adapters, can install traditional and professional CF propellers
Recommended to work with Dualsky MRP series propellers to achieve best working efficiency 
Recommended to work with Dualsky MR series ESC (up to 433Hz control frequency) 
100% inspection in Shanghai Dualsky factory before shipment.
