NTM Rotor Drive, our latest addition to the NTM performance outrunner motor range are high quality brushless outrunner motors designed specifically for use in today's high performance electric model helicopters. The NTM Rotor Drive motors feature high quality, precision made Japanese ball bearings ensuring long life and excellent performance in your high-demand R/C helicopter. They also feature a flat spot on the shaft for pinion mounitng.
NTM Rotor Drive motors are rock-solid performance outrunners with tight windings, quality bearings, correctly rated magnets, balanced stator and flux rings 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.
Perfect for use with Trex 600E, Trex 550 and other .30~.50 size electric helicopters using 6S power systems.
