DualSky XM7010MR-7.5, short shaft, 1100W

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 Foxtech Supreme series or other decent carbon fiber 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
