This is a Dualsky 70E Tuning Combo with ECO 4120C V2 500kv Motor and 80A ESC

ECO V2 has made great improvements in many respects. It brought new electromagnetic design, more competitive performance and efficiency, long-time endurance and water-proof. This is new ECO V2.

1.Classic Dualsky five-spokes back cover with simple lines. The nuances are quite different.

2.Traditional Dualsky color matching (silver-black-sliver), anodized and matte finishing

3.Multi-surface rotating laser marking, Logos, model and traceable serial number

4.Motor structure strength increased by 25%

5.Optimized stress distribution and strength increased but it did not increase the weight.

6.High strength and high toughness main shaft (HRC48)

7.The rotor limit adopts 2 insurance modes of circlip and stainless steel chocks

8.High temperature resistant, high toughness epoxy glue

9.Due to the above optimizations. The impact resistance increased about 10G, and the survival ability is greatly improved.

10.High precision double sides dynamic balancing

11.Adopt NMB ball bearing, durable and low noise. ECO 41 and bigger, equipped with 3 ball bearings

12.Optimized heat dissipation ways

13.Motor working life significantly increased by 50% (same load and working environment)

14.Modular design: main shaft, case and accessories (propeller mount and motor mount) are all compatible with the upcoming EA series. Besides, the design of propeller mount is completely implanted from GA series.

15.Up to 500V insulation level. The stator is coated with insulated-coating and completely insulated after winding.
