NTM Prop Drive motors are rock-solid performance outrunners with tight windings, quality bearings, correctly rated magnets, balanced stator and flux rings, tool-steel shafts 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.
A HK YEP 60A is a good choice too! It has a better SBEC !
Very impressed with this motor. Very well made and no slop or bearing noise to speak of. I've installed it into a CMP cessna 182 weight approx. 2.7kg. Running on 4S2P 2650mah 20C Flightmax, Otter 55A ESC using a 3 blade 12x8 APC prop (no thrust measures as yet but I would guess approx. 2.5kg of pull). The following is a reading using fully charged packs for about 30secs. I will update the review after my first flight.
Great motor at a great price. You must buy the accessory pack as I tried fitting another prop adapter to it but they are completely different to the SK series motors.
Awesome quality for the Price...Used it on my .40 class Piper Cub (Balsa) lots of power stays cool!

Im using this motor with a HobbyKing 60A ESC, and a 12x6 2 bladed prop with power coming from Turnigy 20c 3300 lipo. I have it mounted on a Hangar 9 Cessna 40 and although it does fly, it certanly struggles to get off the ground and is not very fast in the air. After 7 minutes of flying time the battery is very warm.

I am very satisfied with this motor. I have installed it in a scratch built,68" span Ryan Navion. The motor is spinning a 13x8" prop on 4 cells. Plenty of power. I am using a 60 amp esc. This is a great value from Hobbyking. Motor runs very smoothly and is quiet. I plan to buy another. Quality is outstanding.
