NTM Rotor Drive, our latest addition to the NTM performance outrunner motor range are high quality brushless outrunner motors designed specifically for use in today's high performance electric model helicopters. The NTM Rotor Drive motors feature high quality, precision made Japanese ball bearings ensuring long life and excellent performance in your high-demand R/C helicopter. They also feature a flat spot on the shaft for pinion mounitng.

We have performance tested these motors against other popular heli motors on the market today such as the Align 450MX motor. In our testing the NTM Rotor Drive motors not only offered better efficiency, but also much higher current handling (in upwards of 20%).

NTM Rotor 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.

No issues, only thing I found a little strange was the motor wires were stiff and stayed in whatever position they were bent. Did give the feeling they would snap if bent back and forth too much

Bought it for HK 450 heli. This is not fit. Different distance for mounting holes, comes without screw. HK 450 using 3mm screw and 3.17mm pinion holes. This one has 2.5mm mounting screw and 3.5mm holes. Building my first heli from scratch so I did not know about differences pinion and mounting holes. I hope this info can help someone else with similar experience :)

Purchased this motor for a HK450 pro and it wont fit unless you grind away to carbon frame i think its a waste of money also wires are solid not flexible wont recommend this one

Great motor, run very efficient on a hk 450 pro FBL TT. But remember its not 3.17mm pinion, you need an align 3.5mm pinion.

I've tried several replacement motors on my B450x, and so far this has been the best. Fitted with a lynx slant 12t pinon, I still have plenty of power for sport 3d flying on my tired batteries. Drop in a 13t if your batteries are a true 45c rating. Contrary to the description it is 6 pole, and note that it is a 3.5 shaft and 2.5 mounting holes.

I've just bought one of these. The issue isn't the mount centres nor the screw size. It's the fact the shaft is 3.50mm and not the standard 3.17mm so my pinion doesn't fit.
My fault really, should have checked. Just got to get a new pinion now. Not the cost that's an issue, but had I realised atvthe time I ordered it I could have bought a matching pinion at the same time.
Or a different motor. . . . . .

Preisgnstiger, sehr starker Motor fr den 450er Heli. Die Verarbeitung ist Erwartungsgem nicht ganz so schn wie bei einem Align oder Scorpion. Der Statortrger ist scharfkantig genauso wie die Lcher im Geblse. Auf der Glocke war ein trber Schmier, der mit Aufkleberentferner runter ging.
Motor luft vergleichsweise leicht mit wenig Rastmoment. Kein Lagerspiel und vibrationsfreier Lauf. Wrde ich wieder kaufen.

I've just bought one as recommended for a HK-450GT PRO V2 3D Belt-Drive Helicopter Kit.
The bolt holes are not 16 x 16 mm but 11 x 11 mm instead, which doesn't match the receiving part of the hell (would need 16 x 16 as specified above. The bolt thread isn't 2mm - 2.5mm may be correct if it's not imperial.

Disappointing - I'll have to buy a different one, hoping that it will fit.

Excellent motor for my 450 TT PRO V2. So much more torque and power than the motor I was using before. Before I was flying with a lesser motor and crashed more than once due to a lack of power when I needed to get out of a hairy situation. With this motor I can hover at near half stick as long as the battery lasts with great control and an excess of reserve power when i need it.
