DUALSKY DRIVE UNIT 40E (TC.5A.40E)

Drive kit designed for Class 40E electric models.

Included:

• Dualsky ECO 3520C kv820 V2 motor
• Dualsky XC65A-Lite 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 commonly used 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 from 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 on the rotor so any impact on balance is eliminated
• product aimed at intermediate aircraft and multicopter pilots guaranteeing high quality at a low purchase cost
• product packaged in an aesthetic box

Dualsky 65A XC-65-Lite regulator:

Lite series 65A speed regulator, very wallet-friendly but superior in quality and features to low-budget regulators from other manufacturers. In the development of these regulators, user feedback and expectations were taken into account, so that very good and reliable Dualsky solutions are now available to a wider range of customers.

Because of the high precision of power control recommended for 3D models.
