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.
