DUALSKY DRIVE UNIT 300 (TC.3A.300)

Propulsion kit designed for models of the 300 class. For this kit we recommend propellers in the range of 7×4 - 9×5. Suggested Dualsky 800-1200mAh packs .

Kit consisting of:

• dualsky 2308C-1180 motor
• 22A Dualsky XC-22-Lite regulator

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

In the ECO series engines, the model designations have been changed making them similar to the one known from 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.

Dualsky's ECO series motor family covers the range of the most commonly used drive units: from the smallest to those with 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 motors:

• 25% more powerful design compared to the ECO series at the same weight
• engine longevity increased by 50% compared to the previous ECO series
• reinforced axles
• dynamically balanced rotor
• optimized heat dissipation
• waterproof stator - ready to work in 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)
• 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 protruding on stator side
• reverse mounting possible, hub to bolt onto rotor included
• cross mounting bracket and screws are included in the set
• aluminum alloy motor housing, CNC-machined and anodized
• nMB bearings
• n4SH magnets
• model markings are laser engraved on the rotor, thus eliminating any impact on the balance
• the product is aimed at intermediate aircraft and multicopter pilots, guaranteeing high quality at a low purchase cost
• product packed in an aesthetic box

RPM regulator 22A Lite series, very wallet-friendly but superior in quality and features to low-budget regulators from other manufacturers. User feedback and expectations were taken into account in the development of these regulators, so Dualsky's very good and reliable solutions are now available to a wider range of customers.

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

Basic parameters:

• 22A continuous current (maximum power 244W)
• instantaneous current 30A (maximum instantaneous power 333W)
