This is a short shaft version of our popular NTM 28-26 1100kv brushless outrunner motor. It is built with no external shaft allowing you to easily mount this motor to your multi-rotor frame without the need for any modification.
NTM Prop Drive motors are rock-solid performance outrunners with tight windings, quality bearings, correctly rated magnets, balanced stator and flux rings plus they are QC checked at 14 points, from material processing all the way through to final dyno test.
Because we design and build these motors completely in-house (from 3D/2D drawing to materials sourcing, machining, balancing, final assembly and dyno) we can completely control production and ensure product consistency from design right through to shipping the product to you. The removal of middle-men has meant we can drive better value to the market and retail these motors at factory(our) prices! All performance figures are real and tested on our own motor dynos.
Our QC engineers check and balance each motor before shipping to the HobbyKing.com warehouse.

Motore molto valido nelle prestazioniAs others have stated the bearings let these motors down however it isn't as simple as bad bearings the problem is actually with the recess the bearings push into. It is only the top bearing that is problematic on my motors, I have 4 and all are poor. Out of the motor the bearings feel fine however when you push them in it closes up and becomes 'notchy', clearly the recess is machined just a touch too small.
In addition you might notice the motors making a noise which I found to be due to radial play. There is a small grub screw which holds the casing to the shaft allowing you to adjust the preload on the bearings reducing the clearance.
The rest of the motor seems fine however I can't recommend them due to the above problem and am considering trying to get my money back.I ordered 4 of these for a quadcopter. In the initial testing, one of them does not work at all and another runs rough. The other two seem fine. Also the recommended accessory pack has the wrong hole pattern for the bottom attachment.Ordered 4 and at least two have rough feeling bearing that rattle, all four have play in them. I opened a support case for them and hobbyking have not even had the decency to reply.Smooth, powerful and cheap, I put them on a SK450, motors react very quickly to stabilize, and takes off like a rocket when you mash on the launch stick. No issues like others have said.Nice motors, pretty good build quality and no rattling bearings. Really. I've read tons of reports about bearings being bad on these motors. And even if they were bad from HK, they are cheap and there are higher performance bearings available too.
Anyway, these motors start to smell at about 15Amps. Didn't drove them to 20 and hope I'll never will but I'm sure they will burn in 10s. at 20A.
But, If worst comes my way, I'll rewind them with better wires.
Running them on 30A BEC-less Multistar ESCs.Die Motoren haben Trotz Ihrer kleinen gre Leistung ohne Ende. Sie versetzen meinen Quadcopter mit X666 Rahmen in Extreme Geschwindigkeiten. Was mich jedoch strrt ist das die Motoren von anfang an Spiel in den Kugellagern haben.tres bon moteur, fonctionne parfaitement avec une helice 9x5 e-prop, une lipo 4S 5000mah et un esc Hk blue serie 30A.
j'en ai commande 8 pour mon mini octocopter FPV. merci HK.I have 8 of these on an X525 converted to an X8 to compete my friends SkyHero Y6.
I also have three of them on an FPVlabs Tri-copter. Hundreds of flights, dozens of crashes and all are still running strong. Correctly rated and BALANCED props go a long way in reducing premature wear. Over propping any motor or having a too heavy craft will eat the bearings up. Go with 8x4's if you are running 4s, you will use almost 60pcnt less power than the 9x6 while only loosing .2kg of thrust. 9's are fine on 3S. I wouldn't put 10's on at all.
Another tip is to throw away the bullet style nuts and get some nylock nuts, the bullets are virtually impossible to balance.Fantastic motors! They run cool even under a very high load, and are almost silent. Great set of motors for my quad(1-1.5kg)!
