NTM Prop Drive motors are rock-solid performances 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.
Perfect Kv and size for quadcopters!
Our QC engineers check and balance each motor before shipping to the HobbyKing.com warehouse.

sin duda los mejores simpre moton todos mis drones con este motor 0 fallosExcellent price-quality
very good!on 4s with 12x6 3blade props pushing 1.26kg thrust eachBrand new out of the box and seriously out of round. Not even flyable. This would shake the copter so bad the flight controller wouldn't work.3 of these are running my tricopter swinging 10x4.7 props on Blue series ESCs flashed with SimonK. Great motors.its for my tricopter...really smooth and nice motor...arrived within more than two weeks and fast shippingTerrible motors for using on quads have used twice outside after performing half dozen indoor test flights on the second outdoor flight motor failed and destroyed my quad. On inspection the top bearings on all motors where destroyed and one had lost a C clip. The top bearing is not suitable for the job as it is smaller than the bottom yet taking more load. Removed the bearings from motors and cut open the insides were not pretty. Deciding wether to upgrade them to ceramic bearings but in all honesty i think these motors should be kept to planesPut these on my first quad. You need to check the small grub screw that locks the shaft into place. Mine fell from the sky when the motor body complete with prop separated. On closer inspection the tiny grub screw that hold the shaft in place had been put in cross threaded and was holding just enough to let it fly, it then let go sending a prop and case off and the quad down. No great damage but based on the description should have been picked up on the QC.very good motor for the moneySeveral tests propeller:
I hope that this review has helped some
