Scorpion starts with high quality aluminum alloy parts that are produced on the latest CNC milling machines. These parts are then gold Electro-Coated to provide a beautiful, long-lasting finish. The stators are epoxy coated to prevent shorts, and are wound with wire that is rated at 180 degrees C (356 F). The magnets used in Scorpion Motors are custom manufactured to be able to withstand high temperatures, making a motor that is virtually impossible to burn up in normal use.\u003c\/p\u003e\n\u003cp\u003eScorpion Motors are built to last, and are backed with a 2-Year warranty against defects in materials or workmanship. However, due to the high RPM of these motors, and the fact that we cannot control the installation and setup, the bearings are not covered by the 2-Year warranty, nor is any subsequent damage caused to the motor by a bearing failure. Bearings are a normal wear item, and as such, need to be maintained and changed periodically. For maximum life, make sure that a sufficient gap is left between the pinion and main gear during motor installation to avoid binding, and put a small drop of oil on each bearing every 5-6 flights. It is the responsibility of the pilot to ensure that the bearings are maintained properly.\u003c\/p\u003e\n\u003cp\u003eFor the best overall combination of quality, performance, and value, use Scorpion Motors in your helicopter!\u003c\/p\u003e\n\u003cp\u003e*This motor is using 30mm bolt spacing on the mounting with M4 Screw holes\u003c\/p\u003e\n\u003cp\u003eHK Patent No. : HK1141674\u003c\/p\u003e\n\u003cp\u003eChina Patent No. : ZL2010 2 0298704.9\u003c\/p\u003e\n\u003cp\u003eTaiwan Patent No. : M399539\u003c\/p\u003e\n\u003cp\u003eGerman Utility Patent No. : 202012006207.7\u003c\/p\u003e\n\u003cp\u003eU.S Patent No. : Pending\u003c\/p\u003e\n\u003cp\u003eAll Others Worldwide Patent : Pending\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable class=\"spec\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eStator Diameter\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e45 mm (1.77 in)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eStator Thickness\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e40 mm (1.57 in)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eNo. of Stator Arms\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e12\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eNo. of Stator Poles\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e10\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eMotor Kv\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e315~580 RPM \/ Volt\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eMax Continuous Power\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e10000 Watts\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eMax Continuous Current\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e\u0026gt;150Amps\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eWeight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e700~725 Grams\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOutside Diameter\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e56.7 mm (2.23 in)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eShaft Diameter\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e5.98\/7.98 mm (0.23\/0.37 in)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eBody Length\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e72 mm (2.83 in)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOverall Shaft Length Maximum\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e127.3 mm (5.01 in)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eMax Lipo Cell\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e12s~18s\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eMotor Timing\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e5deg to 15 deg\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eMax Peak Power\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003e15k Watts (2 seconds)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eMax Peak Current\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"right\"\u003e\u003cspan\u003eUnknown due to ESC Limitation\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWeight including packaging\u003c\/h4\u003e\n\u003cspan\u003e960g\u003c\/span\u003e\n\u003ch4\u003eFull Dimension\u003c\/h4\u003e\n\u003ca href=\"http:\/\/www.scorpionsystem.com\/files\/i3,169_full_dimension.pdf\" onclick=\"window.open(this.href);
