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.
Can I change the position of the shaft, pulling it from the opposite side?
What should I do?
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.
