Description

Dualsky XM2838EG-14L, 860KVAn affordable alternative to gearbox inrunners. Here's a neat idea, an out runner with an extended shaft for use in electric sailplanes with slender fuselages. The extended motor shaft and bearing housing allow the motor to be mounted 22mm aft of the firewall. The idea is to provide enough room between the motor bell and fuselage side for the motor wires to pass by without being abraded by the spinning motor bell. The long shaft motors feature longer

 An affordable alternative to gearbox inrunners. 

Here's a neat idea, an out-runner with an extended shaft for use in electric sailplanes with slender fuselages. 

The extended motor shaft and bearing housing allow the motor to be mounted 22mm aft of the firewall. The idea is to provide enough room between the motor bell and fuselage side for the motor wires to pass by without being abraded by the spinning motor bell. 

The long shaft motors feature longer stators and lower winding counts which provide the greater torque necessary for turning larger diameter propellers. The motor extension tube contains it own large ball bearings that support the extended 4mm motor shaft. DualSky has chosen to use a locking collar instead of an e-clip to retain the motor bell and shaft. They believe that machining an e-clip groove into the motor shaft would weaken it. The locking collar can be removed if there is a need for more exposed motor shaft for the propeller collet. 

Like all of DualSky's products these motors are very well machined, have tight windings, tight magnetic tolerances and use quality components throughout.

Please see the detailed drawing above to determine whether this motor will be a good fit for your particular aircraft.

Pretty Colors to Encourage Me to Walk!
Size: X-Large, Color: (601) Bittersweet Pink / Stone / Stone
Hum. Extra large does not seem extra large. I have a slender but size 10-10.5 foot. Will keep but was hoping for a looser fit. Bought to match an Under Armour walking outfit.

I stay on your foot they don’t slip in your shoe
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit
