Overview
DarwinFPV HULK 2204.5 is a brushless waterproof motor designed for FPV quadcopter builds. It uses stainless steel bearings and conformal coating (“three-proof” paint treatment), plus a protective shell structure to improve dustproof and waterproof performance and extend motor service life.
Key Features
- Waterproof and dustproof construction: stainless steel bearing, conformal coating, and protective shell design to reduce sand and rain interference
- Safe and reliable M5 shaft design for more secure propeller locking
- N52H ARC magnet design for continuous output
- Image note: a comparison photo is labeled “Motor after soaking for seven days” (Common Motor vs Darwin HULK Motor)

Details

Water-resistant construction helps the HULK motor keep running after prolonged exposure to water compared with a typical motor.


Performance data is provided for both KV options to help match the motor to your prop and battery setup.

The dimensional drawing confirms the 12mm mounting pattern and M5 shaft details for accurate fitment on builds.
