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.
Can you put 4 of these motors on a f-450 sized quadcopter? I am new and looking to build a quadcopter that will be scary to fly...I want it to fly fast ( 100pmh fassst ) and climb like a big hummingbird on steroids...Thanks.Hope someone please answer me...
high kv motors will drive smaller props. it is recommended for quadcopters to use low kv motors (up to ~ 1000 kv) to drive bigger props. this achieves a good and stable flight.
for high speed and aerobatics, its recommended to use high kv motors ~1300-1600 kv to drives slightly smaller props.
but this motors has a very high kv for use on a large quad like the 450.
i'm not saying it wont work, it will. but that will sacrifice stability so much that the quad will be very twitchy.
unless you are a pro in quad flight, i'd recommend you use a more stable setup.
quads aren't designed for very high speeds like 100 mph!
this one is not exactly a real lightweight. keep in mind that for most gliders you'll need a quite heavy engine in the nose as you'll need the weight to balance the plane.
I've installed the engine in a zagi that was coated with carbon-fibre... I'm still quite afraid that I'll be losing my ailerons :-). This is a quite powerful engine, for a glider I would suggest a lower kv to allow you fly more smoothtly and use a bigger propellor
Hey guys, I have a problem. I've used this motor on my radjet for awhile and seems like it doesn't give nearly the amount of thrust it used to. It doesn't scream like it did couple months back. Could this be the motor or my ESC?
It can be your battery as well (is it high discharge 90c, i had the same problem an found out my 4cell turned into a 3cell (one cell died) can be the bearings/connetions/loose magnet i would check all of the above. This is one though motor im building/modding a Radjet at the moment ,got any videos of yours? , i was going to use a 35mm series NTM but after seeing this perform , i might use this 28mm
I don't have any videos of mine but it used to be super quick. When using a 3s 2200mah 25c nanotech, I rarely went above half throttle because it was so quick and I had unlimited vertical with the half throttle. And I've used couple different LiPos, the best one being a 4s 35c zippy which has less than 5 cycles. I seem to get less thrust with it on full throttle than I got with 3s on 3/4 throttle awhile ago. I've had some crashes so that may have contributed to the lack of performance.
Hallo ich kann diesen Motor nur empfehlen habe ihn in den Pylon von HK eingebaut. ESC 60 Ampere 4s 2200 mAh. Der Flieger geht mit einer Luftschraube von 5 x 5 ohne Ende. Top Produkt der Outrunner von HK!
With a 4s i recommend a 70a esc with a max prop of 4.75 x 4.75 , make shure the battery can handle the amp draw use high discharge 4s 40c , This set up pushes my little .5kg jet to 250kph https://www.youtube.com/watch?v=SsWD_NXQKqg
Tenho um Skyfun jet, equipado com este motor, ESC "Hobbyking YEP 80A ", baterias 2250 mah, 4s, 65-130c e hé*lice 4,75 x 4,75.
Tenho duvidas sobre a melhor configuraç*ao do esc, por isso gostaria que me dessem a vossa opiniao e se nao for pedir muito, explicassem o porque.
Motor timing: 0°*/6°*/12°*/18°*/24°*/30°*
Start-up power: 2%/4%/8%/16%/32%
PWM frequency: 8kHz/9kHz/10kHz/12kHz/14kHz/16kHz
Active free-wheeling circuit mode: Freew. off/Freew. on
Muito obrigado pela atenç*ao.

wilson hi.. ucan try out first ground test using amp/ waat meter to see how much current drawn in to the motor... try 4sel 1300 25c to play safe., if the waatage just half of the max waat, so u can use 6x5.. for me it is to much, motor may burn some days.. try 6x3 or 6x4 and just use lipo 3sel high C rate.. that enough for size 1meter length jet..
burned up two 3 sell 2200mah batteries that were 30c rate with 6x4, so went to 4 sell 40c 2000mah they come back a little on the hot side after 4 min flight but usable with a 5x3 prop. I would stay away from 6x4 hope that helps
hi loucas.. 4sel 2200 35c is too much, otherwise u can control ur throtle as limit as 75%, mine burn one, same spec as u said. im just using prop 4.25x4.25. after chage to 3sel mode, then use bigger prop 5x5 and sometimes 6x4, my jet scream with no fear now n forever...
Exactly right afxdz. You can use the 4 sided star mount on one end or turn the motor around and attach the adapter to the end of the motor with the 3 black bolts and attach your prop to that. A great idea, I use nothing but NTM motors in all my ARF or upgrades. A word of warning, if you mount it this way make sure you battery can't be forced into the rear facing shaft if you have a nose in crash. It could puncture your battery.
those NTM motor come with back prop adapter
i got the 2700KV with that
Purchased for my Funjet Ultra ...
Hobbyking SS Series 90-100A ESC Turnigy 2200 3s 40c TGS Sport 5x5E Precision propeller Equals..61amp..and 694 watts..
Great set up for little money

Perfect performance here for the low price !!!
275 km/hr: 4.75 x 4.75 ZIPPY 2000 4S 45C = 78 A = 1260W
note: ESC TGY80A = all nicely warm, nothing alarming
3.5 minutes full-speed flight
3XX KM/hr: 6.00 x 5.00 ZIPPY 2000 4S 45C = 132A !!! = 1680 W !!!
note: ESC TGY80A = all "red"-hot, don't try this unless you are prepared to order a new ESC/Motor and have a Heartattack !!!
about 2.5 minutes mixed flight (speedy-runs and 200km/hr cruizing)
We, being myself, the plane, the motor and even the ESC survived this crazy adventure :D
A for the motor and sure for the ESC 80A handling 132Amps...
We flew the bird today at Pattaya R.C. Flying Club and the video will follow ...
Enjoy this "Monster" my dear RC-fanatics!

Great value . Fitted to my Skyfun and it goes like a rocket :) Using 80A esc , 4s 1800mah Nanotech(bought for testing) , 4.75x4.75 apc style prop. Bench test measured 755W with HK watt meter and 32400rpm measured with turnigy micro tacho. Will upgrade to 2200mah packs now I know the setup works well on 4S
