Features

• 28 poles brushless motor, specially designed for High-end Multi-rotor/UAV systems
• Based on proven TE-MR technology, all parts are newly designed
• 2nd generation stator design, still using the best 0.2mm material, improved motor efficiency
• New winding method, lower IR, remarkable lower temperature after long running time
• Detachable stator, easier to maintain
• Imported over-sized ball bearing, low noise, ultra-long working life
• Short shaft design, better to work with MR propellers
• Optimized Dualsky "Star" appearance with precise secondary processing, artistic and high-precision
• high-precision rotor, dynamically balanced on both size, lowest resonance in RC industry
• New stator cover, protect power wires
• Multiple mounting holes, compatible with DJI frames
• Extra long silicone power wire, easier for installation
• Laser-etching model data and serial number
• Comes with full propeller adapters, compatible with both airplane and multi-rotor propellers
• There are two types of motors for each motor size to fit the different flight requirements: high power type and long running time type
• Recommended to work with Dualsky MRP series propellers to achieve best working efficiency
• Recommended to work with Dualsky MR series ESC (400Hz control frequency)
• Fully tested to pass quality inspection in Dualsky Shanghai Factory
