NTM Prop Drive Series 28-30A 750kv / 140w
NTM Prop Drive Series 28-30A 750kv / 140w

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.
Perfect Kv and size for quadcopters!

Our QC engineers check and balance each motor before shipping to the warehouse.

Hello, I'm designing a RC boat to use it in the sea, the controller was an arduino board, but my problem is that i dont know which type of motor can buy to mount it. Is this kind of motor usable underwater in sea? if isn't which one is good or what features must have to work for my pruposes? Thankyou very much

What would be the recommended prop for this? Weight about 1500g. Would like to have both acceleration and efficiency.

i have this motor in my slow stick with a 20C 2200mAh 3s lipo and a 25-30a ESC. it works really well and my battery life is 25-30 min. i have put in an order for 2 more motors so i can build more stuff with it. all i am waiting for is them to restock!

Quadcopter 500mm motor to motor GU344 I got these for my Quadcopter and I used the Blue ESC's 30amp I must say very good motor and smooth, My only gripe is that HobbykingK do not have the Acc Pak with the motor it should not be a separate item.

This motor is very strong and very smooth. In the past I have saw many HK motors with moving magnets but this motor are the magnets locked. The shaft is very hard. the shaft was to long and I want shorted. Thats was very hard to do. I use 2X circlesaws. 750 kv is handy for slow flyers with a lot of torque. I saw a new MTN motor with the same size but more power (250watt)and KV 1200. I have already ordered 7 motors for my WiiMultiHexoCoptter. One bad point is that they have a special mounting system and you must order apart. I recommedation everyone they need quality with low budget. 5 stars for MTN motors!!!
