The Outrunner Dynamic 3100 KV Motor is a great motor for a great low price. It is perfect for 300 size Helicopters such as the Esky, Blade CP, or all CNC Blade CP Belt conversion kit. The motor is 36mm long and was designed for a brushless ESC and a 3 Cell Lithium 11.1V Pack.

With the P19 series motors Hyperion continues the tradition of top performance in motors which perfectly fit your needs. From front to back, only the highest quality materials and components are used. The P19 series have the advantage of high-torque OutRunner design, but are specifically designed for high-rpm applications. FEATURES: 250W watts max continuous power handling capability. Note, that each has a max continuous amperage as well. Max short time current (15 seconds) is 20% over continuous specs, given adequate cooling airflow. Note, however, that the motors can handle much higher currents for shorter bursts, such as seen when helicopters initially pitch up. The amazing P1919-04M for T-Rex 450 class helicopers, for example, can easily handle momentary currents of 35A, and end the flight hardly warmer than ambient weather temperature!

The most popular motor for the QJ-EP8 with a 4-cell Lipo pack and 17 or 18T pinion. Requires an EP8 outrunner motor mount (part #QJ-HBP-34-C). For the Century Swift 16, use an 11T pinion (CNMG511) and a 4-cell Lipo pack. FEATURES: Ultra-high power and super-efficient design. Specifically designed for use with Li-Poly batteries. 20,000 U/min max RPM. Operating range: 3-5 LiPo. Operating current: 35A, Peak current 15 sec: 45A. Shaft diameter: 5mm. This motor is also recomended for the Hirobo Lepton RC Heli.

In order to own the skies you need the power and performance to make other pilots jealous! The motor stays cool even after a serious aerobatic 3D flight. Economic and powerful this Brushless motor is the ticket for the Swift 16 Century Electric Helicopter.

The Hacker A50-14S Brushless Outrunner provides very high power for 600mm heli's using a 10 cell Lipoly 3800mAh pack. Radical 3D performance is achieved on the Logo 6003D with a 18 tooth pinion (8.5:1) on 600mm Blades. 4+ min of all-out 3D flight time on the 10S-TP3850mAh Extreme Packs. The A50-16S achieves excellent power and flight time for 600mm heli's using 10 cell Lipoly (3800mAh). Aerobatic performance with extended flight time is achieved on the Logo 600DX with a 17 tooth pinion (9.0:1) on 620mm Blades. 6+ min of flight time on the 10S- TP3850mAh Extreme Packs. Both features 10 poles with a build in dual fan system for cooling.

High quality high output brushless motors for duration flying and and aerobatics. Kontronik motors are excellent performers and requite no maintenance. The motors use a 5mm shaft and a cooling heat sink is optional.

Brushless, outrunner motor for experienced T-Rex flyers who require high power and rpm. The 500TH is a slightly larger motor than the 450TH and provides higher performance and output. Be sure to choose a 3.17mm pinion between 11T and 15T depending on your heli flying skills. 13T pinion recommended for 3000+ RPM. 11 or 12T for normal flyers. Screws are standard 3mm .5 pitch spaced 16x19mm in X.

Built specifically for use with the T-Rex 450 and focused on similar performance to the 450TH at lower amps. A slightly lower Kv and larger pinion of 14 to 15 should get you the extreme performance you desire. You can also experiment with other pinion sizes from 11 to 13. Stays very cool at high performance where other competitive motors run hot. This is one of the most efficient 500 size motors. Flyers wanting more power should consider the 500TH. The 500SH has a lower Kv and requires a larger pinion or higher volts to get you over 3000 RPM. If you want to go to higher efficiency with less than 3000 RPM on your heli then this is the motor for you.

The Ripper OBL outrunner motors are designed for R/C electric helicopters. Thunder Tiger provides a brand new range of brushless motors to satisfy all your flying needs. Extremely high torque and mass of power for a motor of its size. With the cooling design, you can get the best efficiency out of motor.

This is an ideal powerhouse motor for anyone using a Micro Heli with a brushed motor who does not want the hassle and expanse of migrating to a brushless motor. This awesome upgrade is a quick swap with your existing 300 - 370 brushed canned motor. Use the same wiring and same connector. Simply hook up the + and - and move the pinion over and you are done. And talk about power, coupled with a Lithium pack this motor will make your Heli go ballistic. This is a powerful 42,000 RPM, 21 Turns full ball bearing raced motor. Just what the Doctor ordered, for your Heli that is.

See also the Hyperion ESC and Programmable E-Meter ( Parts HP-TITAN-30P and HP-EMETER )

The Kontronik heat sink will fit on the Fun Series motors as well most other brushless motors. The heat sink will increase the life of a Brushless motor and will allow for the heat to disperse much quicker. Comes with locking screw and nut - Clamp on style !!!

A beautiful anodized blue 20mm heat sink will keep your brushed or brushless motor cool and efficient. The heat sink includes built in internal machined fins for maximum cooling and was specifically made for micro Helis so aircraft aluminum was used to keep weight to a minimum.

This Tail Motor Heat Sink will fit the HP tail motor standard tail motor and Piccolo Pro tail motor. A cooler motor will have a longer life expectancy. The tail motor on the Piccolo is heavily affected by temperature changes and this heat sink will greatly assist in keeping it running cool.

For best cooling results use these 370 or 400 size heat sinks. Also included is a conductive compound ( same type used on computers CPUs ) which will hold the heat sink in place and allow for maximum transfer of hear from the motorﾒs case to the heat sink.

Keep your brushless motors running cool with these heat sinks. Available in 20mm for Micro Helis, 30mm for mini size motor and 40mm for large motors. The clamp on powder coated heat sinks are easy to install and include horizontal fins for increased cooling.

The motor adapter ring is 25mm in diameter with a 15mm length between screw holes and 2.8mm thick. Used to adapt motor to frame ( kind of like a big locking nut for a motorﾒs base )

This CNC machined aluminum motor mount is designed to allows you to use the CDROM motor in your micro helicopter! The kit comes with the CNC machined mount and a stainless steel shaft that has been turned down to 2.3mm.

This is a hard to find tool which is used to advance or retard the timing of your Speed 400 electric motors. Use it so you may produce faster runs ( RPM ) or get a longer run time ( Longer flight ). The tool comes complete.
