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.

I have a 50 size spitfire that flies beautifully but I have the need for speed.do you guys think this motor can power a balsa spitty into the 120mph range?

Can someone recommend the motor mount that will fit this motor ?
 CharlySub 7 points
Motor mount and screws are included with this motor. See the last picture...
 AcTion 132 points
The standard mount provided is big and way too big for the EF1 invictus . Also not the standard NTM 35xx size. I bought the NTM 35 carbon mount but the screw did not line up all the holes in the motor (only 2 out of 4) hence my query.
 CharlySub 7 points
Omg. Maybe its a good idea to drill 2 more holes instead of putting questions here... Have fun *-)
 AcTion 132 points
maybe you should consider if your reply is useful instead of putting lousy replies . i cant drill the carbon mount as the motor holes will overlap over the pre-drill ones weakening the mount. i think i have been rather specific in my question and if you dont have answer , pls dont reply.

I have a foam Mig-29 600grs, can i use this motor with 6x5 prop 4s 2200 ? for speed
 CharlySub 7 points
Too big. Too heavy. You can find a lighter motor. And first you choose the motor and then you calculate the size of the prop.

Recomiendo a los aeromodelistas que practican Racer F1 si compran este motor , que desmonte el rotor y aseguren las bobinas del estator con barniz dielectrico para bobinados (secado en estufa o secado al aire) , es la forma de asegurar que no les pase lo que me paso a mi

Just bought one for my pulse 15e. 70amp esc HK.3s 5000mah35c battery. 12x8apc prop. Pulls 63 amps 759 watts WOT. Checking with my 4 cells next. Without a doubt kills my buds even at 3/4 lead I will beat them down! Super fast! Only buy if you like to go FAST!!! Switching to 10x10 and 8x8 next readings too.

Second test 4s3700c65, 10x10prop, pulls 84amps 1259 watts wot. Beyond Fast! Motor is not rated for this don't use with 4s. 10x10 with 3s5100c50, 52amps 650 watts, works great. 8x8 was good numbers with 4s 68 amps 750 watts wot, but not enough prop for plane to fly right. next props 10x8,11x8,12x8.

10x7 apc prop, 4s3700c65, pulls 68 amps 1050 watts. Crazy fast pulse 15e! 12x4 apc prop, 4s3700c65 pulls 68 amps 1000 watts. night visionaire unlimited 3d! 12x8 apc prop, 4s3700c65 pulls 90 amps 1350 watts. Do Not Even Try! Way beyond limits!

this motor was designed specificly for the NMPRA EF1 racing class although other props can be used the 8X8 on 4s is what it was designed around.

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.
