NTM Prop Drive Series 28-26 1100kv / 252w

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.

after using this series motor for nearly 2 years, i say they are OK for a starter but you will be wanting something more robust after a longer while. Myself, i just keep replacing the bearings every 3 months or so.

Hello JureKD, I´*m having the same problem, but I don´*t know with ball bearing I bought. Could you help me? Thank you

I busted up the internal bearing assembly on one of my motors during an incident which almost took my head off. Once I cleared the tiny balls from the magnets and coils it appears that the bearing could be replaced - anyone with experience in which bearing set to replace with?

I had a similar case, a broken clips in flight. Internal roullement was broke. I have e replaced by a rolling 8/4/3. Before replacing check that there is no part in the throat. target=_blank>Exploded view See : http://www.hobbyking.com/hobbycity/store/uploads/374

i returned two motors since they were defective. when the replacement motors arrived one wasn't working. hk sent two motors free of charge. i mounted the motors and found the speed of my quad to vary. it goes up and down then levels and then up and down. not sure if its the esc or the motors. it was working fine with the kv1000 motors. i waited a little over 4 months for the replacement motors. i'm not sure if the motors are all working or if its the escs that are not working. one problem after another. i don't think i'll buy these motors again. waiting so long i almost forgot how to fly my quad.

i ordered four of these motors several months ago but i had no issues at all i'm still using them in my quad and my plane.
 JurekD 49 points
this is a regular thing with these motors, order 6 to get 4 working ones, one spare and one broken. Busted bearings are a regular occurence with these due to a simple fact that they are undersized. But i still like them. I simply replace the bearings every 2-3 months and they work fine for me. Overall, the performance to price ratio is acceptable, and the price is quite low compared to other 'quality' motors, which may need less maintenance but not zero . . . .

I bought this for a quadcopter, and didn't realize the shaft comes out of the "top" where it mounts (I didn't envision it properly). With the accessory pack that I also purchased, the prop ends up getting mounted on the "bottom", therefore the sticking out shaft isn't used. Is it possible to easily remove it? If not, should I just cut it off, and if so, what is the safest method?

Hi, Got the same issue however I mounted my motor so that the prutruding shaft is pointing down through my copter arm, and using the recommended prop adapter(accessory pack) on the top and propeller as usual facing upward. Coming to remove or shorten the shaft maybe there are already suitable lengthed shafts of same diameter, but replacing them is probably more iffy than just leaving it alone. else remove it and if you have access to a lathe that would be the correct way. Good luck
 canflyr 8 points
Yes, same thing in my case. The shaft part is pointing down. It isn't really "in the way", but I do have wires that run under it, and in the long run I may cut it off with a dremel. I don't really understand the point of this shaft, if you use the prop adapter/accessory pack.
 Stefan 21 points
well for a slimmer design you might mount the motor so it is below the arm with only the prop and shaft-prop-adapter above the arm. one benefit would maybe be a little better protected motor.

Windings are tight, also glued with some epoxy glue i think, strong magnets. GOOD QUALITY of manufacturing and materials EXCEPT from BEARINGS. Bearings are quite bad. They sound not good and there's also a little play in them. In my opinion bearings are a crucial part of the motor, so therefore just 3 stars. I haven't any experience with SK3 motor series, but if they have good bearings, i'd consider tu buy any motor from that series.

bought this because they had it on sale for like 1/3 the price off, ended up using the hobbyking cordless dremel and spending half an hour to slowly cut off the protruding shaft and now my tricopter has a great new tail motor
