- 5S–6S LiPo compatible for flexible electric power setups
- High-efficiency brushless outrunner design for smooth power delivery
- 6.0mm motor shaft for strong propeller support
- 49.5mm × 48.2mm motor size for 70E-class aircraft installations
- 4-M4 mounting holes, 30/30 spacing
- Excellent choice for sport, aerobatic, and pattern-style RC airplanes
515KV vs 610KV – Which Motor Should You Choose?
| Variant | Best For | Flying Feel | Typical Prop Direction |
|---|---|---|---|
| 515KV | Larger props, stronger pull, lower RPM setups | More torque-focused and smooth | Best with larger propellers such as 15×8E, 16×8E, or 17×8E depending on cell count |
| 610KV | Higher RPM, smaller props, sport and aerobatic flying | Quicker response and higher-speed feel | Best with smaller propellers such as 12×10E, 14×6E, or 15×8 depending on cell count |

| Motor Variant | 5S LiPo | 6S LiPo | Setup Notes |
|---|---|---|---|
| 610KV | 15×8 | 12×10E or 14×6E | Higher RPM setup; use smaller props on 6S to control current draw. |
| 515KV | 16×8E or 17×8E | 15×8E or 16×8E | Lower KV / higher torque setup; better suited for larger propellers. |
Recommended Power System
- Battery: 5S–6S LiPo
- ESC: Dualsky Summit 100 or comparable 100A brushless ESC
- Application: 70E class RC airplanes
- Glow Equivalent: .50–.60 2-stroke or up to .82 4-stroke class aircraft
Setup Notes
- Always verify current draw with a watt meter before flight.
- Use a smaller propeller when increasing cell count from 5S to 6S.
- Higher KV motors spin faster and generally require smaller propellers.
- Lower KV motors typically provide stronger torque and can swing larger propellers.
- Ensure proper motor cooling, especially in cowled aircraft.
What’s Included
- 1 × Dualsky XM5050EA V3 brushless outrunner motor
- Motor mounting hardware
- Prop adapter / accessory hardware as supplied by manufacturer
Required to Complete
- Compatible brushless ESC
- 5S–6S LiPo battery
- Suitable propeller matched to the selected KV and battery voltage
- Compatible aircraft mounting setup
Important Safety Note
Brushless motor performance depends on propeller size, battery voltage, ESC choice, cooling, aircraft installation, and throttle use. Always check amp draw and wattage with a watt meter before flying, and stay within the safe limits of the motor, ESC, battery, and propeller.
