4130C V2 DUAL ENGINE - 290kv

ECO-C engine in the V2 version dedicated to aircraft models. Attractive price while maintaining the quality of the Dualsky brand.

In ECO series engines the model designations were changed making them similar to the one known from other popular engines such as AXi, E MAX , RAY, FOXXY etc. Now the name of the engine model is based on the diameter and length of the stator and KV.

The Dualsky ECO series of motors covers the range of the most commonly used drive units: from the smallest to those with a power of 900W. The wide range of KV allows precise selection of the motor for a specific application. Some of them are also suitable for use in multicopter platforms (ECO-X line).

Features of ECO V2 engines:

• at 25% stronger structure compared to the ECO series while maintaining the same weight
• Engine health increased by 50% compared to the previous ECO series
• reinforced axles
• Dynamically balanced rotor
• optimized heat dissipation
• waterproof stator - ready for operation in rain and moisture - NOTE the bearings are not waterproof!
• NEW LABELING RULES based on stator diameter and length and KV (revolutions per volt of no load voltage)
• a wide selection of models in the most popular sizes up to a power of over 2000W and optimally matched KV parameters
• standard length cabling with factory-soldered connectors (connector sockets for soldering on the controller cables are included in the set)
• motor shaft protruding on the stator side
• reverse mounting possible, hub for screwing onto the rotor is included
• Mounting cross and screws are included
• Aluminum alloy motor housing, CNC machined and anodized
• bearings N MB
• N4SH magnets
• the model markings are laser engraved on the rotor thus eliminating any influence on the balance
• a product aimed at intermediate pilots of airplanes and multicopters, guaranteeing high quality with a low purchase cost
