NTM Prop Drive Series 42-48 650KV / 1295W
NTM Prop Drive Series 42-48 650KV / 1295W

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.

Our QC engineer checks and balances each motor before shipping to the HobbyKing.com warehouse.

I love this motor, its installed in a RiffRaff and spinning a master airscrew 12x8 schmitar prop, great speed!

Are you running it on 6s ?
 firstfishon 10 points
Yes, I'm using the Aspec 3700-6s battery, with that combination I'm pulling *65amps with *1300 watts, very good power and speed.

This is one of my favorite motors but are not avilable at the moment, I'm waiting anxiously for HK to get these back in stock.

Hello, can I use this engine on a 3 kg high wing trainer -as Adalberto- but with a 10x6 or 10x8 propeller?

Hi, You could but it would be a gross overkill!

Can I use this motor on a 3kg high wing trainer with 4 cells and a 13x6 3 blade prop?

Which is average plane's weight this motor could handle???
 Ronaldo 45 points
I fly a Slick 540 50E with this motor on 5S with insane power. For a sport plane I think you could go comfortably to a 60 size. I think my plane weight is around 2.2kg. Build thread and video www.link

Do I have to disassemble the motor to add some glue to the magnets? I would like to use a toothpick to add a tiny amount of glue for insurance, but I am uncomfortable disassembling the motor. Also, JB weld makes a cold weld, metal infused epoxy that is designed to withstand up to 550 F when fully cured. Would this be a good choice for gluing/reinforcing magnets?

I bought this motor as a replacement for a 4250 SK 650kv. I am running it in my 63" P-51D with a 13x8 prop 5s 5000mah 30-40C Lipo. I get excellent performance. Put it on the box and it ran at 1375 watts 77amp draw at full throttle. It seemed fine. It didnt get all that hot and I am comfortable wit these numbers. However this motor lacks a prop shaft. Lucky for me I have access to a full machine shop (metal lathe and Mill) and I was able to myself a prop shaft from 6061 Aluminum to match the plane. BEAUTIFUL. Couldnt be happier and will certainly buy another soon.

Motor looks great, but it doesn't come with prop drive or mounting plate and attendant screws. I think you should mention that in the description. Also the prop drive is 3 screw mounting so the mount will have to be peculiar to this motor. I can't use my other Turnigy prop drives.
