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.

Motor's internally glued (fail) stator came unglued and damaged the coils.
HOBBYKING FAILED TO HONOR THEIR WARRANTY SAYING I "OPENED" THE MOTOR AFTER SLIDING THE STATOR FROM THE OUTER SHELL.
Find a different business, these people are a joke.I'm using this motor in a 3D hobbies YAK and it has gobs of power, way more than is needed to 3D this plane. I'm using 6S and a 15x6E APC prop. I did have to replace the retaining clip on the shaft after a dozen flights or so but have not had any issues at all with the rest of the motor (no problems with magnets, etc.) at least yet. For the money it is quite the powerhouse.Sweet motor, I installed it in a phoenix tiger 3 40 to 55 size
With turnigy AE 80amp speedie 6s turnigy 5000mah battery
13x8 apc prop it's pulling 1598watts at 64 amps only had the chance to fly it once (dam work keeping me from flying ) it has awesome
Power great vertical, when I pulled up it almost went out of sight
Can't wait to get out this weekendThis motor is NOT shown with any mounting hardware, but it does say which mounting hardware to order. Secondly if you look close at the motor picture you can clearly see that the mounting hardware needs to go were the motor shaft is, or you need to mount the motor inside the mounting interface so that the shaft is pointing forward.Hello After putting this motor in my P40 ( 1650mm )on 6S with 16*10 prop it's power is very good. Only my motor became loud, checking motor and also this motor from NTM has loose magnets. HK you should do something about this because all bigger motors from NTM have this problem. In you're add saying only quality etc but loose magnets is the worse thing that can happen with you flying yours expensive plane....

Without these components the motor is worthless.An excellent motor, mounted into a Wot 4 XL with a 100amp ESC, original motor was a SC 120 4 stroke, don't really notice the difference other than the noise and cleanliness of the plane when flown, my view is ya can't go wrong with this...Great, keep up the good work HKjust got this motor ,it appears to be well made.have test run it to 40 amps so far no problem but would like to know what brand/type of prop hk used for their test dataThis is a strong Motor. I fit it in a 81" Piper. First I tested the engine in a test bench.
I use a 5S Zippy-LiPo 4500 mAH
