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.
I want to run my new 28-36 2700KV with 3s and a 6x4 prop on a Jim Fox Airblade. The ESC is a Plush-60A. Unfortunately I do not know which timing I must set. The possibilities are: Low 3.75 degrees, Medium 15 degrees, High 26.25 degrees. Thanks for your help!
Thank you Ben! I have some 3C LiPos, so I will begin with these - but later I like to try with 4C. I still got no answer about the timing and I hope to get instructions from an "Electric-Professional", thank you in advance!
Can someone please tell me ( it felt like I was talking with a 5 year old on live help ) if i can use these motors on a 450 size quadcopter and have 8.4 size props on the motors. Thanks. I am tired of looking up different motors for the best results...and i am very well aware that alot of electric motors despite the huge price disparagement are identical from the same factory. google: " How to compare electric motors and what do their specs mean." I just want to if this motor would be an excellent choice for pitch climbing/ having a GoPro to video...and it will not burn like a piece of ****? Thank you in advance. i appreciate it...
8x4 prop will overload this motor. Based in prop test data, 6x4 - 11.1V / 520W / 46.8A / 1.2kg thrust. For the sake of efficiency, multirotors should have low KV motors so you can use large props. The NTM motors with 750kv-1200kv rating is more appropriate for your purpose. Some motors which are specially designed for multirotor use have kv ratings as low as 240kv.
motor is great but today i had a 5by4 prop on 3s 2200mah 30c and both batteries puffed ussually i use a 6by4 and the batteries were just slightly warm
did i just get unlucky with my batts or what because both flight the batts got killed and i know i didnt overwork anything
any comment on this would be appreciated thanks.
Ben. i had the same problem with my NTM's. I put a 4 cell battery ( same power as the 3 cell i use) and my engine just smoked and melted at half throttle. Reading the forum i think these engines are like BMW's........good when they are going but expensive and temperamental. I bet your 5x5 prop swinging off a 2700kv engine like this melted your gear. What size ESC did you use........i hope nothing under 70 amp!. Best combo for this engine is a 6x4 Prop/ 70 amp ESC and a 2200kv/3 cell/25c battery.
i had a 60 amp esc still fine i think i just over discharged my batts they where like 1 year old they still work but their performance is just slowly dropping im going to go to 4.75 on 4s nano a-specs and see if i can break 100mph haha
.Scratch build airplane ~500g
.Birdie 50A ESC
.2200 3s battery
I run this motor with the birdie ESC ok but it only for a little while.
After the run the ESC gets really hot and the motor does not spin or spins in ***ps very very slowly.
Any ideas as to why? for my setup It should not draw more than 50A, right?
I recently purchased this motor for my Bixler.
My setup is usually 2200 mah 3S 25C, Hobbyking SS Series 50/60 A ESC and a 5x4 Prop. The motor gets very hot for some reason. Unfortunately I dont have any testing equipment such as a watt-meter yet, so Im prone to testing it with very options. I have also tried a 30C battery as well as a smaller prop with it.
The motor even completely shut off and kept spinning in alternating directions afterwards.
Now, according to the test data with the prop I used, it should not exceed 50A. What am I doing wrong? Could it be that my motor was broken in the first place?
A ntm 2700 on a Bixler!!! What is the point. Thats like putting a V8 in a nissan Micra. Lots of noise but not much performance. I threw a 2826 2200 Turnigy engine in my bixler and it went vertical but a NTM 2700 is twice more powerful. Up to you but if you want speed get a RadJet 800 for $50.
i use this motor at 3S 2200 mah 40C with a Turnigy Super Brain 80A
but starts to slow with fastet option programmed!
what for a low resistance have the motor?
wich PWM rate? for this motor?
Some ESCs have limits on RPM. I tried this recently and when I used my 70A ESC from another model it did the same thing, seems to accelerate then slow down a bit. When I tried it with a 40A ESC I've been uding in my Bixler I could get full RPM from the motor. So my guess is the Turnigy Super Brain has a limit on RPM, likely design to be used with lower KV motors.
Every motor has it limitation, this motor could run on 6X4 prop with a moderate speed and reliable. It will not blow your motor, esc and batt. The performance of this motor is about 65% of HET 2W-25 but again compare at the price, in short worth buying
I need a ESC that is used for this set up 6x4 - 11.1V / 520W /*** 46.8A**** / 1.2kg thrust Would you tell me which one to purchase. Anything but TST-SBEC55A TURNIGY TRUST 55A SBEC Brushless Speed Control I bought this one and it was a bad one.
I would use the H-KING 50A Fixed Wing Brushless Speed Controller. That is what I am using with this same motor and it works great!I have also used thes ESC's in other models and have not had a problem with them. for $16 you cant beat them, and they come with a BEC! Here is a link www.link Hope this helps
I'm using the same HK 50A Fixed Wing Brushless Speed Controller. But I would go for a 70 Amp Speed Controller. You could later on use a 7x3 or up to 8x4 prop and the amp draw, power and thrust would be higher on a 3s battery.
I purchased this motor and tested it with a Hobbyking Watt-tester and got almost exactly the same test results, the power rating depends on the voltage that the motor is supplied and the current that it draws, the kv rating depends on the number of turns of wire in the motor. If the motors use different wire then they won't handle the same current/power. Safest is to test on a work-bench with a watt meter for a few seconds and see if the motor gets hot.
yes There are more of a prop drive motor. The difference between a prop drive and an edf is the KV rating. The more KV the faster the the motor will spin. You want the motor to spin faster with and edf because there is less strain on the moter with small fins. With a prop drive motor the lower the KV the bigger the prop you can spin. Think of it this way. The higher the KV the more speed you will get and the lower the Kv the more power you will get to spin a prop. This motor however would most l
Ok so no other difference.
So I can use this motors for edf`s.
Will be very good for the 10 blade fan 70mm!
On the other hand less kv -> gve him higher Voltage!
But they have also the 3000kv version here with 755w so its not for props only.
Yes and you can step up to a 4s 60 esc when your're ready to go faster- just cut your prop size down till the motor is warm, cut a finger hole for this or better yet a lazer temp reader,OF couse if have a telemetry radio and heat senser use it!
A 3000 to 3500KV 1000watt would be a better choice if you are a better then above average on the stick, as it will run up to the 150mph ranage with a 6s, 100 amp esc. NOTE should be installed only Ultra Funjet
Not realy , but that at least gives some clue of what the motor is REALY going to perform.
What I was asking is a graph of REAL TEST like some other NTM motors have in their description so then one can choose the prop you want. After all Hobby King says each NTM motor is dyno tested before delivery , its simply a copy-paste of that test screen so no much work to do .
That is it .
By the graph you can se REAL (not estimated of theorical ) test data for a given voltage.
You can see the eficiency curve to see from whitch range of amps (and wats) has the higer values and given the wats you need you select a prop that matches those wats/amps.Having the graph for various motors lets you choose between them knowing whithc is the REALY better for your aplication.
Just want to say, AWESOME MOTOR!! Make sure to buy the accessory pack for this motor as it will comes with an adapter to allow you to use it as a pusher, (putting the prop on the opposite side of where the shaft is). I put this on my pz stryker f27q and it boogies up to 100mph!! Tried it on 4S 4.75x4.75 and it was just as fast as a 3S with 6x4 but the 3S setup made the plane fly more stable for some reason so I keep it on 3S... With a 75 amp castl esc, I tried other prop sizes, going one size up and down and faced problems... Keep it to these prop sizes and nothing should go wrong!! Over 40 - 60 flights and counting, pushing strong with NO end in sight!!! GREATTTTT MOTOR!!! (I got the EXACT same result on the 3000kv but more speed!!!!!!!!!!!
great motor so far 5x5prop 5s 1800 mah 40c-50c. 1340watts and 79amps. its very very fast on my scratch built pusher 29inch wing span. would probably be better with a 2200 mah. comes down quite warm but ive had it flat out.

This motor is awesome, motor is very powerful and it took my model for vertical take off effortlessly. T-50 PAK FA is made of Foam Board was not as light as the plans suggested but this motor proved them wrong. I placed a video on this model to prove it.

are the motor power info correct?
6x4 air screw with a 3s lipo 520watt?
what someone has written up by 5s lipo and 1340 watts that can not be when the engine is only up to 4 s or?
funny funny: D
The motor ran very smooth and it does what it should do on a 3s lipo, so well done!

I use this motor on a scratchbuilt pylon like plane with an APC 5,5x4,5 and a Zippy compact 4S 3200-35C ( two 1600 batteries in parrallel ) and I am quite impressed by the performances .
Static test with battery at 10pcnt of discharge to avoid the initial peak gives:
79,3 A at 1129 W and 14,2V .
Motor mounted as a pusher in front gets maximum cooling and comes down cold , outside temperature was near freezing level .
Motor runs very smoothly and with a buddy code, you can't be wrong with this motor . 5 stars more than deserved .
