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.
Perfect Kv and size for quadcopters!
Our QC engineers check and balance each motor before shipping to the HobbyKing.com warehouse.
I use this motor on a 9x6 APC slow flyer propeller. It has incredible thrust for such a small motor. Never once had the propeller break in 40 flights. Current draw at full throttle is 26amps. The slow flyer propeller draws a lot more current per propeller diameter but delivers more thrust with a smaller diameter.
What are the best props to use for this motor on a multirotor? I'm hoping to run a 4s, since it theoretically holds more power (in watts) than a 3s. But I don't want my drone to catch fire mid-flight. Any suggestions?

bearing problem yes,bought 4 to use in a quad.replaced upper bearing in 3 motors before 1st test stand spool-up.strong motor though,smooth when right.
have not had the need to change a bearing yet myself . I would figure it is around an 10mm od x4mm id x5mm size bearing or close to it. It would be a common hobby bearing that you should be able to get at your LHS or bearing supplyer.
prop is not mounted to the shaft but to the adapter that is mounted to the can on the oposite side. Think of your motor as having two shafts of different diamiters and you are using the larger one that is threaded.
The pic of the accessory pack has a cone shaped part on the right. it is a mounting plate for the other side of the motor that has a threaded shaft on it and the cone is a shaped nut that will hold the prop on. This part is mounted on the can of the motor ( non shaft side ).
Lost it because of too much of a "C" rating on a battery? That doesn't make any sense. The motor/ESC combination will only pull what it needs from the battery. It will not pull more amps simply because the battery has a higher "C" rating. On the flip side of this, the battery must have AT LEAST a high enough "C" rating to accommodate the amperage being drawn from your motor/ESC combo. It is much preffered to have a lipo with a higher "C" rating than required, and there is no such thing as too big of a "C" rating. Again, the "C" rating of the battery tells you how many amps can be drawn safely FROM a particular battery. Batteries do NOT simply THROW out amperage to a motor/ESC. Amperage is DRAWN by the motor/ESC. So, an ESC/motor combo that has an amperage draw of 32 amps with a 12x6 prop using a 20c 2200mah battery (which can safely handle a 44amp continuous draw). The same motor/ESC combo and 12x6 prop will still only have an amperage draw of 32 amps if you were to use a 100c 2200mah battery (that can safely handle a 220amp continuous draw). Again, the battery only supplies current that is drawn, and no more.
The motor is running way outside of its specs. My guess is that a bearing is bad at the very least, at the worst a bad motor. Even the slightest resistance from a bearing going bad will cause a higher amp draw. Good luck.
this is a great motor for quad or plane I used it for my flying wing AUW almost 1.2kg with 3S 3300mAh TGS 9x6E props, gonna test it with 10x5 with 3S see how much power I can squeeze out of this great motor
1) Which right?:
The description reads: 11x5.5 - 11.1v - 200W - 20A
Comments: 11x5.5 - 11.1v - 293w - 27A - 1220g
2) What is the thrust at 3S LiPo and "APC Style Propeller 9x6" ?
3) What is the thrust at 3S LiPo and "APC Style Propeller 10x5" ?
I have a Hexocopter on the HAL frame with 6 of these motors. What props would you recommend I use? I am going to use it for camera work.I already have Slow Fly Electric Prop 12x4.5 SF but they seem very cheap. I do not want my hex to fall out the sky because of the props.
DO NOT use the cheap plastic props. Mine broke half a blade on in flight. i managed to land without crashing but you really should run crabon plastic composite, or APC or all carbon. the all carbon props are EXPENSIVE. 35.00 FOR TWO
I've used several kinds. 10x45 plastic slowfliers that HK sells works, but not really recommended. I've snapped those propellers midair on 4S setup. I used 12x3.8 APC SF on a different quad with NTM 35-36 920kv. Pulls 40 amp and works really well. I just got Grapuner E-Props (10x5) to try with these motors now. I think you should be ok with 10x3.8 APC's for your setup, make sure the ESC gets good cooling as I suspect you might be over it's rating. In that regard you would be better off with 4 single esc's as you can put them in the airstream. Good luck *)
Hi, Im looking to put that motor in a Mini FuntanaX, to replace my current Eflite Park480 910kv... Im running a 12x6prop with 35Amp esc, on 3S 2200... Would that motor be a upgrade? Same kind of power? Thank you, Max
if you not running it at full trottle with 10 inch props you will get 26 amps of draw and the plush can take 10 second 40amp so just ride it hard fews second and let it hover to reduce heat , but yes the watt meter is very useful to see if your props are to big
I have plenty flight time on a quad with these motors and 10x4.5 props with 30 amp plush esc's and both 3 and 4 cell setup works just fine. Depends a bit on flight style but for LOS flying you will surely have no problems.
yeah.. you probally havehave some fun a battery with a low c rating..i run mine with nano tech's..and fly them purty hard..when i land the only thing even slighty warm is the battery.i can heat up 30 e.c.s with 28's..why not spend a couple more dollars for bigger e.s.c..you'll be safe.plus you can upgrade later and not have to buy another set of E.S.C..since i swapped to Ad50Q pro i hot rod the **** out of my multis..bottom line get out their and fly..
Newton Centimeters. Google: "n Cm" found this: 10N-cm = 0.885074 lb-in
Good quality BUT....
For the price & size it should come with a prop adapter, mounting screws & female connectors. It's just the motor. Recommend HK to add the above mentioned items. Runs great on the bench...

Well, I bought four of these for the quad, but realized later that they do not come with the prop adapter or motor mount hardware? Thats lame because it uses 3 hole instead of the more standard four hole pattern.
Really needs this included!

This is a great motor for its price, ugly as hell, but so what! I run a 10x6 4 blade on a 3S 1550 25C battery. At WOT static it sucks 32.3A and delivers 363W at the battery level (Wattmeter)and 80 efficiency (Motocalc). After flying, it comes down still room temperature!
