Product overview
The FlashHobby H550 Helicopter Motor is a motor component for helicopter propulsion. Its specified dimensions are 44.6mm in diameter and 59.5mm in length, with a 35mm stator diameter and 38mm stator height. Mechanical integration interfaces include a 6mm shaft, a 95mm overall shaft length and a 30x25mm motor mount designated M3*4. The electrical interface is a 5mm male connector. A 120A ESC is recommended, without being identified as included equipment.
The H550 carries conflicting electrical and construction specifications, leaving its exact configuration unresolved. Its description ratings are 1220KV, 3-6S LiPo, 98A maximum current and 2200W maximum power, alongside an introductory 9N/6P configuration. Detailed ratings instead specify 550RPM/V, 3-12S LiPo and 12N/10P construction, with continuous limits of 60A and 3000W. Peak ratings of 80A and 4000W each have a two-second limit. Detailed settings also specify 5deg motor timing and an 8KHz drive frequency.
