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.

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

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.
