Description

Dualsky XM2838EG-7, 1800KVAn out runner motor designed specifically for electric gliders. A longer stator and a higher wind count results in a motor that has the torque to spin the larger propellers generally found on electric gliders. This motor will best fit an electric glider that has some room in the nose. The motor wires will need clearance between the fuselage wall and the motor bell. If your glider has a slender nose, have a look at DualSky's long shaft motors also

An out-runner motor designed specifically for electric gliders. 

A longer stator and a higher wind count results in a motor that has the torque to spin the larger propellers generally found on electric gliders.

This motor will best fit an electric glider that has some room in the nose. The motor wires will need clearance between the fuselage wall and the motor bell. If your glider has a slender nose, have a look at DualSky's long-shaft motors also found in this category.

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

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. 

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

Scent: Unscented, Size: 70 Count (Pack of 1)
Will continue buying these since other trash bags I’ve noticed a lot of leaking. Great for cleaning out cat litter can hold up a good amount of weight.

Fantastic towels at a great price on subscribe and save
Package Size Name: Family, Size: 286 Count (Pack of 6)
As an oil painter, Viva are the gold standard for wiping brushes and whatever else you need a towel for while painting. I bought them for that purpose. I didn’t count on loving these paper towels for every other paper towel duty in my home. These paper towels are incredibly hardy, and perform much like a thin cloth towel. They last and last. I can rinse and reuse a towel to clean all the kitchen counters plus clean the stainless steel gas cooktop. All with one section of paper towels. I couldn’t do anything close with any other brand I’ve used. I love the select a size feature. For quick cleanups, one section is more than adequate. I’ve used one section in my swifter handle when I’m out if swifter cloths (which is always- I never buy those things), and used both sides of the towel to dust mop my wood floors. I use these to dust my home with a little spray wax, cleaned the tires on my car with no towel shredding, and scrubbed the filthy barbecue with bleach cleanser, rinsed it out, and scrubbed some more. These towels are tough yet soft, sturdy and disposable. They are soft enough to use as a napkin, and absorb like crazy. I buy mine by the case from Amazon subscribe and save every three or four months, and love saving 20% doing so.

Viva is the best and, by usage, the most economical paper towel
Package Size Name: Family, Size: 286 Count (Pack of 6)
Still basically the same Viva. I compared this version with the prior one I still had on hand. This one has a slightly woven vs felted appearance and the side against the roll is slightly rougher or textured, while the outside face is slightly smoother. The inside face looks as if it might leave lint, maybe. Half sheet size is the same and both versions absorbed one ounce of water. Both seemed equally thick, judging by the amount of see-through-ness, both dry and wet. Both seemed equally tough wet. This version clings to the roll less firmly, too. Viva is the very best AND the least expensive paper towel available based on how long it lasts. It takes weeks to go through a roll, especially if you realize a sheet can be reused to wipe up more than one small mess while you cook and you need many fewer to clean up the big messes. Use one to dry a pot and leave it by the cutting board to wipe up. If you're used to ordinary paper towels, there may be a period of adjustment, but try to take just one sheet instead of the 4 you may think you need; you can always get another. They can scrub an iron skillet or pat dry your food. They make the best handkerchief substitutes, too. One subscribe and save box lasts me about a year.
