Product overview
The Rctimer A3542 1250KV 1450KV Outrunner Brushless Motor is a propeller-driving motor component supplied with motor mounts. Its outrunner architecture has a 35 mm diameter, 42 mm long body and a 4.0 mm diameter, 61 mm long shaft. Both the A3542-5 and A3542-4 configurations weigh 130g, providing the same stated body envelope and mass for installation planning. Both specify a 2-4Li-Po battery and a 50A ESC. Selectable KV values are 1250KV, 1450KV and 1000KV.
The A3542-5 combines a 1250KV rating with recommended 8x7/9x5 propellers, 580 W power and approximately 790g pull. Its idle and load currents are 2A and 17.8A, with 0.021 Ω internal resistance. The A3542-4 combines 1450KV with recommended 12x5/11x7 propellers, 595 W and approximately 1180g pull; its corresponding currents are 2.1A and 33.0A, with 0.019 Ω resistance. These configuration-specific propeller and electrical specifications guide propulsion integration. KV value and motor size can also be made to order.
