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 engineer checks and balances each motor before shipping to the HobbyKing.com warehouse.

I'm using this motor with a 9x6 3blade nitro style prop, a pair of zippy 4s 2800mAh and a 60A HK esc. This setup is for a 2.2Kg - 72" bixler style FPV pusher plane and prop space was an issue. The autonomy is over 20 minutes and it's crazy powerful but becomes quite hot with this setup: about 60 degrees C on the casing. I don't have what it takes to measure the amperage but I'm fairly certain that this is too close to the motor's limits so I will change the prop for a 9x5 3blade GWS prop instead.

Kraftvoller durchzugsstaker Motor. F das Geld ist der absolut zu empfehlen

I orderd 6 of these motors, none of them had perfect bearings, two being almost perfect and one being slightly louder than the other three. They will work just fine but some people like to complain about that sort of thing. The rotors are all pretty well balanced (most phones vibrate harder), I'm not going to complain about that. Windings also seem to be fine and well packed. I intend on running these with 10x5,5 props on 4S LiPO, but I'm currently missing some bigger ESCs so I cant properly load them down to properly test that config. Note that this is just a motor without any accessories which are sold extra. It's an OK product but Iplusll give it 4 stars because the bearings aren't quite there.

Disappointed. Had one good flight with this motor and it has been a problem ever since that time. Overheats at power levels > 350 watts. The motor wires are very stiff and apparently have cracked, broken, or shorting out (with heat) at the entry to the bell. With better wire this could be a great motor.

This motor is a monster on crack. Wide range of props and applications. I have used a 12x7, 13x4, 13x6, and more. Just hook it up to your watt meter and watch your numbers. These NTM motors are one of my first choices, great price too. I have put my way over price E-flite motor's on the shelf for these not because of price but because of power.

Got this motor in my PZ Sukhoi after I ditched the stock setup. A lot of people are wondering if this motor can handle the listed amps and I'm happy to be the one who says it does, and then some. Throwing a 12x6 APC on a 4s brings the static amperage up to right at 70 amps. I have flown the absolute crap out of this motor and it barely comes down hot, running a 85 amp esc with plenty cooling for the motor though. My Sukhoi is now a completely out of sight vertical rocket that I would put up against anything in its size. For the price this motor is a gem among gems and the quality is what I've come to expect from the NTM line of outrunners.

I am very happy with this motor. The dyno graphs are helpful but I think the motors are better than we would think looking to the graphs. So I have measured the 3 most important motor parameters. Kv was 1085/V; Io is 2.4A at 11V; Ri is 0.028 Ohms.
This gives a calculated max.Efficiency of 85pcnt at 12V and 13A.

I run this motor on 4s with a 10x10 APC and pull about 65a and 900w on a 1100mm Spitfire. I reach speeds just under 100mph with no problem. The motor gets pretty warm if I run WOT the entire time, but it takes the extra watts with no issue. Great motor for the cost!
