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.

A charming summer suit
Color: Light Grey, Size: 6, Color: Light Grey, Size: 6
This suit fit true to size. The light grey wasn’t exactly the same as advertised (see photo), but I still really like it. My son felt snazzy in this suit, and he said it was comfortable to wear.

Nice suit for the price!
Color: Light Grey, Size: 12, Color: Light Grey, Size: 12
This really is a very nice boys suit, especially for the price they are asking. My kids don't wear suits too often, maybe once or twice a year for special occasions so I don't need really expensive suits for them. The material is actually really nice on this. The color looks great and the pieces are sewn nicely. The adjustable waist band is really nice on the pants because my kids are on the slimmer side and this helps with fitting. You can also wear a belt with these if needed. I washed on delicate cycle and dried on delicate cycle a little, then finished by air drying. They washed and dried very nicely with minimal wrinkling. The front pockets are real and useable on these, which isn't always the case with boys suits. Overall would 100% recommend

Nice looking suit that runs big
Color: Light Grey, Size: 6, Color: Light Grey, Size: 6
This is a beautiful light, gray linen suit size 6. It looks high end and it is a baggy fit, not slim. This suit is double breasted with a satin lining inside. There are two pockets in the jacket and one small smaller pocket for a handkerchief on the jacket. I did order a size 6 but this fits way too big for a size 6 I’m thinking it was more like a seven or an eight. The pants have a zipper, which moves very easily and 2 pockets. The Pants have belt loops. Both the the pants and jacket are longer than normal. My son is tall, so I was really surprised that these are so baggy and so long. I would definitely double check the size. there’s no size chart online so maybe I would go one size down. It does look like a quality made suit. The sizing is just off.

Suit is light weight and perfect for my son's homecoming dance. Sage color is as described and fit was accurate as well. Nice suit and material for the money.
