Turnigy SK3 Motors are the next leap forward in motor quality and design. We instructed the engineers to source the best quality magnets, bearings and materials available to them and develop a motor that would not only rival but surpasses the quality of many leading motor manufacturers on the market today.

The result is an efficient, high caliber motor using quality double shielded bearings, sintered Neodymium magnets and a string wound stator ensuring an accurate and consistent winding each and every time.

The Turnigy SK3 motors are suited to modelers who are seeking a quality brushless motor without compromise.

*This review contains no scientific data, only anecdotal and personal feelings.
So I bought this as an upgrade to my electric longboard. The original motor was some generic 5054 that worked alright but could not move me up even the slightest of incline (I weight in at around 285-290lbs) even thought the board was rated for 290lbs. This motor was so strong that it broke the original motor mount after the first use so I had to fabricate a new one. Even though the new mount was 1/8" thick steel the motor was able to bend the plate when using the engine braking. I have since reinforced the steel plate with 1/8" aluminum angle stock, and also ordered a better pre-made mount. The shear amount of torque this motor generates is very impressive, it has no problem moving me from a dead stop and actually gains speed while traveling up slight inclines. Basically, I'm super impressed with the power of this motor, just wish I could fit two of them on my board.

Great product for lightweight electric vehicles. I'm currently using this motor with 8s lipo to power a fixed gear bicycle (friction drive). Motor is spec'd for 14s and 70amps, but gets me (160lbs) up to 18mph at 8s with about 20amps.

Rock solid construction, and the windings arent done too bad at all either. Actually purchased a 2nd just to avoid shipping if i need another one. If this is in stock and its in your budget buy it now, sometimes take a little while to restock.

Listen carefully, I set up this engine on an extra 260 2,40m and 9kgs! I started with one and now a 23x8 25x10! These engines do not heat and do not consume too much and it is not power that impresses but the torque that can cause large propellers. I much prefer the G160 and Rotomax 1.40 and 1.60. I am very happy with this cheap and efficient engine.

This motor comes with a 10mm prop shaft that bolts on the front, and an 8mm to 10mm collet shaft to go on the motor shaft, it tightens on very tightly and can be hard to remove, so no set screws should be needed. This motor has loads of torque. I use it on my mountain board with a 6s 8000mah lipo, and an 11 tooth and 68tooth #25 sprocket set. On a level surface it draws less than 3-5A during low to medium acceleration, and can maintain speed at less than 1-3A. It draws 15-20A with low to medium accel up hill, and can draw over 25A doing a burnout on level ground. My board goes about 9-12mph. It is best to give it a small push with throttle to start it, so it doesn't loose timing. The brake on the YEP 120A ESC is at the lowest setting (acro) which is a little too hard to use much faster than walking speeds, so I jump off then hit the brake. The ESC has been staying cool without the fan on. It is programmed with 4pcnt starting throttle, but I might try 8pcnt. It should go 4.5 miles of mixed throttle with some small hills on one charge.

Super Motor fr meine Pilatus Turbo Porter an 12S

Put this engine on an old Top Flite Stinson Reliant, 100.5" wingspan, 22lbs flight ready with batteries, running a 20/8 prop, two 6s 5000mah batteries in series. Pulled 45 amps, produced 15lbs of thrust. Flew great!! After a 5 minute test flight battery cells still showed 3.92. Looking forward to testing it with a 24" prop, see if I can increase minutes in the air. Good replacement for 30cc gas

Great motor. I've put 2 of these on my mountainboard with 15:64 reduction (HTD5-15mm belts) and with 20 cm diameter wheels I get 35 Km/h of maximum speed (with an 8s LiPo) and a torque and acceleration that are just insane (can climb a hill on grass with 2 people on the skate without problems. Range is 10 Km with a 5 Ah battery.

This motor is basically the go-to choice for powerful yet lightweight small electric vehicle drive systems. It's basically the slowest outrunner in this size available (even the former 80xx and 120xx motors are too fast for their size), making it compatible with some of the inexpensive electric bike ESCs which perform current control and have other useful EV features. Hall sensor add-on packages are available for this size as well (search your favorite search engine for SK3 Hall Sensor or similar). Typically 1500plusW in a vehicle application on 36v with a capable controller.
