Turnigy SK3 brushless motors are yet another step forward in motor evolution.

Once again we instructed our engineers to develop a motor that would not only rival but surpass the quality of the leading motors on the market today using the best quality magnets, bearings, and materials available.

The result is an outstanding series of motors that are efficient, strong, and robust enough for the most discerning modeler.

All of the SK3 series use quality double-shielded bearings, sintered neodymium magnets (the strongest type of permanent magnet commercially available), and a string wound stator to ensure accurate and consistent winding each and every time.

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

• Double shielded bearings
• Sintered neodymium magnets
• String wound stator
• High-quality finish
• Super-smooth operation

Benutze den SK3 5045-660 KV in einer RASCAL 80 mit 4S 3800 oder 4S 5000 Akku mit einer 15x8 Luftschraube und einem 70 A Regler. Viel Power und wenig Stromverbrauch.

That's a pretty good motor - it flew a rebuilt Sig Kadet Sr. with ailerons very good.

Super Motor!!

Nov 04, 2021

Fliege den Motor in einem Entenmodell (Speed Canard) mit 1700 mm Spannweite und einem Gewicht von knapp 4 Kg.
Angetrieben von einem 6S 5000er Lipo. Prop 13x8
Strom ca. 35A bei Vollgas im Horizontalflug.
Läuft super, kann die SK3-Serie generell sehr empfehlen :)
Hab schon viele Motoren davon verbaut...

Best replacement motor for FMS P51 Mustang 1450mm V8

Apr 28, 2021

WOW! I am totally impressed!!! Put this motor in my FMS P51 Mustang, and its hands down by far the best motor I've installed. Way better than stock, and and a little better than the FMS KV650 upgraded motor recommended by FMS. I was able to keep my 14x8- 4 bladed prop for scale looks, and is the fastest it ever been.
Heres my set up. Factory FMS 14x8-4 bladed prop. CNC small parts prop adapter. 4s- 4000 mah Admiral lipo. She runs at 50amps, and 800watts. Test was done in flight. Go to CNC small parts .com for the prop adapter that bolts right on the motor and fits the FMS factory prop assembly. Fast enough for me. Flight time does suffer a little, but the plane really comes alive. Highly recommend!!!
