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 warehouse.

Could I power this motor with a 6s lipo ?
 greasmnky 738 points
Yes, I think so. I have not done it, I would try a 13x6 or 7 prop on 6S. I run mine on 5S and I use a master airscrew 13x7 3 blade. That pretty much maxes out this motor.

Yes no problem. I use a 14x7 3 blade prop and I get about 7 mins flight with a 4s 5000mah battery. Might be better with a 15x7 2 blade though. I draws about 46A so a 60-70 amp esc handles it no worries. Anything less than a 4s battery your probable wasting your time, this motor seems to suck up a lot of power. I tried a 4s 2200mah and it was gone in about 4 mins. This is a well made motor and I'm pretty happy with it...........

hi. whats is the size propellor that need to use for 3d kind flight with a 5cell battery Does anyone have a recommendation ? Thanks.

On 5S the best prop is a 14X7 APC or wood. This is my setup on my Skyline Slick 540, you may see a video here: https://vimeo****/128686700

hi, what is the best propeller for this motor with a 3s 2200mha?
 greasmnky 738 points
You probably would need to run at least a 60C battery and even at that your flight time would be incredibly short. This motor gobbles the power. If you are dead set on this combo, I would try a 15x7 prop or in that neighborhood. Possibly even a 16x7.
 Gravelsandwich 2 points
Agree.......15x7 is about right. 4s 5000mah is a good combo..................

Hi guys, will this motor run on 3s? If so, what prop should I go for and what will be amp draw?
 connypilot 57 points
Although designed for 4s to 5s, the motor will of course run on 3s. But 650KV and 11.1V will mean only 7200 rpm idle or about 6000 rpm (maybe less!) under load. So you will need a huge prop! In the reviews is reported the use of a 15 x 8 prop with 4s. With 3s you will need a bigger prop, e. g. 18 x 9! I think this is no good idea. Choose a motor with higher KV, say 900KV, and a 13 or 14 inch prop!

Hi, I am new to RC Hobby. Please advise me how good is 4 of these motors for a 4.5 Kilograms quadcopter? Will it give ample lift to it? Thanks, Devarjun
 Josh 11 points
If you use a 4s battery on this, you will probably get about 1.5kg of thrust (x4 with 4 motors is 6kg). Normally you want to get total thrust to AT LEAST 2x the weight of your copter. You can probably get close to that with a 6s, but I am not going to say for sure it's a good idea. I would suggest getting a slower KVM motor, or load your stuff on to a hex.

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.
