DUALSKY DRIVE UNIT 70E (TC.6A.70E)

Drive kit designed for 70E class electric models.

Included:

• Dualsky ECO 4120C kv500 motor
• Dualsky 80A V2 regulator

V2 version ECO-C engine dedicated to aircraft models. Attractive price with Dualsky brand quality.

The ECO series engines have changed their model designations making them similar to that of other popular engines like AXi, EMAX, RAY, FOXXY etc. Now the motor model name is based on the diameter and length of the stator and KV.

The Dualsky ECO Series motor family covers the range of the most common drive units: from the smallest to the 900W. A wide selection of KVs allows for precise selection of a motor for a specific application. A part of them is also suitable for use in multicopter platforms (ECO-X line).

Features of ECO V2 engines:

• 25% more powerful design compared to the ECO series while maintaining the same weight
• engine life increased by 50% compared to the previous ECO series
• reinforced axles
• dynamically balanced rotor
• optimized heat dissipation
• waterproof controller - ready for rain and humidity - NOTE bearings are not waterproof!
• NEW DETERMINATION 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 over 2000W and optimally matched KV parameters
• standard length wiring with factory soldered connectors (connector sockets for soldering on regulator cables are included)
• motor shaft extending on stator side
• reversible mounting option, hub to bolt onto rotor included
• mounting cross member and screws included
• aluminum alloy motor housing, CNC-machined and anodized
• NMB bearings
• N4SH magnets
• model markings are laser-engraved onto the rotor so any impact on balance is eliminated
• product aimed at intermediate aircraft and multicopter pilots guaranteeing high quality at a low cost of purchase
• product packaged in an aesthetic box
