HOBBYWING RTF 5320-350KV BRUSHLESS MOTOR
The Hobbywing RTF 5320-350KV is a brushless motor for 8S LiPo propulsion systems. Its 52.9 mm stator, 620 mm motor leads and 30 mm mounting pattern suit builds using the manufacturer-recommended 16–18 inch three-blade propellers.
This is the 350KV version. Hobbywing specifies 1520 W rated output and up to 11.2 kg thrust under its test conditions. Maximum current and power ratings are time-limited; see the specifications and propeller-specific test data below.
FEATURES:
- Integrated propeller-mount cooling structure and anti-slip contact teeth.
- 0.2 mm stator laminations.
- Rotor retention using copper washers, retaining clips and screws.
- 14 AWG motor leads, 620 mm long.
