Dualsky XM3040EG-9 1350kv Brushless Glider Motor; suit F5J


The XM3040EG-9 brushless motor from Dualsky is suited for FAI F5J gliders. Weighing a mere 104g and able to develop 400-500W this motor is perfect for F5J gliders weighing up to 1800g.

Features
•    Suitable for FAI F5J Gliders
•    Over-sized hollow shaft, front bearing
•    Three-point bearing distribution results in a strong resistance against the impact of landing
•    Based on the design of EA V3 high-torque systems
•    Active cooling fan
•    15% more power than the Dualsky EA motors


Product Information
 
The Dualsky XM3040EG-9 brushless motor has a unique capsule type protective canister design, presented in the form of an in-runner with the wires located at the rear of the motor. These changes make the motor suitable for the nose of an F5J or similar RC glider. Lightweight, with a 5mm shaft so hard landings pose no problems.

Dualsky XM3040EG-12 Brushless Glider Motor (560W); suit F5J

 
The Dualsky XM3040EG-12 brushless motor is lightweight, and compact, and is designed for medium to heavy F5J gliders (up to 2,000gm).

Features
•    Encapsulated design for easy integration into the slim nose of gliders
•    Wire outlet at the back
•    Integrated fan for optimized efficiency
•    Shaft is mounted on 3 bearings distributed over the entire length for better resistance during landings.
•    14 pole rotor composed of curved magnets, 0.20mm Japanese silicon rolled steel, providing high direct drive torque.
•    Uses 220 grade enamel wire and same level high temperature epoxy adhesive, with five star grade overload resistance


Product Information
