Lightweight brushless outrunner from Dualsky's ECO-C V2 series, wound at 14.5 turns for 2300KV and built for 100–200g aeroplanes — indoor freestyle models and EPP F3P trainers are Dualsky's own examples, and it's equally at home in park flyers and small sport models where thrust-to-weight does the flying.

At 23g with a 120W burst ceiling, the 2304C-V2 delivers the performance-per-gram this class demands from a 12N14P wind on 2S–3S LiPo. The V2 revision is a genuine step up from the original ECO-C: a new electromagnetic design for more torque and efficiency, splash-waterproofing throughout (rust-proofed shaft, insulation-soaked windings, coated magnets) so a damp field won't end the session, and roughly 10G better impact resistance — a survival trait worth having on models that live close to the ground.

Propeller guidance from Dualsky's spec sheet: 8x3E (or PT 9x2.8i) on 2S, and 5.1x4.5E on 3S — start there and verify current with a wattmeter, keeping burst draw inside the 15A limit. Dualsky recommends their XC-12-LITE or XC1210BA ESCs as the matched controllers. Connection is by factory-soldered GC2.0 connectors, and the cage-side prop fixing suits prop-saver-style mounting. The modular shaft, case, and accessories interchange with Dualsky's EA series.
