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 Specifications RPM/V: 205 Weight: 690g Turns: 11 Dimensions: 63.1 x 59.5mm Slots & poles: 12N14P Ri(mOhm): 43 Io @10V (A): 0.8 No. of cells (LiPo): 10 or 12 Max Efficiency Current (A): 50 Max.
