Dualsky ECO 5330C 205kv Brushless Motor

Dualsky ECO 5330C 205kv Brushless Motor

The Dualsky ECO 5330C 205kv Brushless Motor is the electric equivalent to a 1.40 – 1.80 4-stroke engine and is designed to suit FAI F3A and popular 78″ 3D models.

Features

• Five spoke back cover with simple lines
• Motor structure increased by 25% compared to the previous ECO series motors
• Optimised stress distribution and strength increased without increasing the weight of the motor
• High strength main shaft
• The rotor limit adopts 2 insurance modes of circlip and stainless steels chocks
• High temperature resistant, high-toughness epoxy glue
• High precision double sides dynamic balancing
• Optimised heat dissipation ways
• Motor working life significantly increased by 50% compared to the previous ECO series motors
• NMB ball bearings, durable and low noise
• Modular design: main shaft, case and accessories (propeller mount and motor mount) are all compatible with the upcoming EA series. The design of propeller mount is completely implanted from GA series.
• Up to 500V insulation level. The stator is coated with insulated-coating and completely insulated after winding
• Waterproof splash, rust-proof main shaft, coil soak insulation, electrophoresis components and coated magnets make ECO V2 waterproof (excluding the ball bearings), and no problem working in wet or rain environment
• N4SH magnets
