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.
smoked a brand new one of these today......why???
running 1045 props on a turnigy hex copter* 20A opto ESCs and dji naza gear... is that ok for this motor? or what else need changing. hex is built for gopro footage, no other loading bar the FPV gear.

Windings are tight, also glued with some epoxy glue i think, strong magnets. GOOD QUALITY of manufacturing and materials EXCEPT from BEARINGS. Bearings are quite bad. They sound not good and there's also a little play in them. In my opinion bearings are a crucial part of the motor, so therefore just 3 stars. I haven't any experience with SK3 motor series, but if they have good bearings, i'd consider tu buy any motor from that series.
bought this because they had it on sale for like 1/3 the price off, ended up using the hobbyking cordless dremel and spending half an hour to slowly cut off the protruding shaft and now my tricopter has a great new tail motor
