Description

Officially recognized and approved by the NMPRA, this EF-1 motor is the ideal choice for your electric pylon racing model. It has been designed specifically for use in EF-1 racing offering the ultimate in performance and efficiency. A complete accessory pack is included with this motor.

NTM Prop Drive motors are rock-solid performance outrunners with tight windings, quality bearings, correctly rated magnets, balanced motor bell 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 engineers check and balance each motor before shipping to the HobbyKing.com warehouse.

Wow, what a hot rod! Seems to run well, but with an 8x8 APC prop on 4s, my amperage is WAY higher than they advertise on the product page. Mine is pulling 60.7 amps, for a total of 866 watts during static tests on a 4s pack. I'm happy...but don't skimp on the ESC. This thing is power hungry!

Bought 2 of them, the 1st one grilled after its first 3 minutes of flight! During that flight i never went over 55 amps: https://youtu.be/MEwWMDU9KVU wanted to install the 2nd one i bought, problem pin axle was loose, tried to screw it, then i realised than the screw thread itself was broken! What a shame to sell and promote this kind of crap! I almost crashed an rc plane with 800€ worth of equipment because of this motor, you shouldn't sell those!

As with all my ntm motors, it looks good, the magnets feel tight, I bought this motor to replace an unavailable 840kv motor, which has since come off back order, so into the "spare" motor box it goes, for another project, another day...

If you need a little more power to get your plane racing across the sky then look no further than this highly tuned and precisely engineered NTM motor .. capable of 900W power output this is my choice for planes up to 2kg in weight .. highly recommended

I had great expectation in this Motor. Unfortunately very disappointed. The engine pin got loose every second battery. And this not even running on a 8x8. Just an 8x6 on a 4S pulled the thing apart. There is no possibility to tight the screw so hard that it will not get loos again.
So in theory cool. Practice... probably I got a "Monday" fabric. or wrong construction.
