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 warehouse.

Dear all, I am very happy with this motor. We did a comparison with two other official approved EF1 motors. They all three had exact the same performance only this motor cost the half the price!!

just got two of the Generation 2 motors and was at the EF1 race at Old Julian Airport last weekend. I had not mounted or tested these motors but, a friends motor died in his racer and we took one of the new motors and put it in his Wagner Solution and it preformed very well for the 8 races it flew. I plan on putting the other one in my Shoestring and hopefully they will have more of these motors available soon. The only thing they could do better is to increase the bullet connectors size from 3.5mm to 4.0mm. The silicon insulation on the motor wires and the small flutes on the back of the motor case to keep the wires separated is a good quality touch.

WELL I HAVE ORDERED 2 OF THESE for the invictus planes , along with yep 80 amp escs . they are a very smooth running motor , combined with the nano tech 2650 mah 30-70c 4s batteries they pull 1038 watts peak and settle at about 61 amps 960 watts with the rec 8x8 apc props . seem well balanced with no resonance on any throttle position .

I don't know where these guys get their prop data from...mine benched 50A with apc8x8 using 3300 4s 40C turnigy lipo. run thru a plush 60 esc. I tried to get close to the max amp level of 65 with a 5S 2700mah nanotech. at 80 percent throttle I saw 63 amps and shut it down. after only 2 small bursts on the bench, right out of the box, there was a little bearing play on the motor. other than that, it looks very beefy. can is 38mm diameter.

So far a tough little motor.
Excellent bang for your buck.
I just hope that it doesn't fly apart like the Turnigy SK3 its replacing.
