T-MOTOR's original page presents this model through its construction details, electrical limits and propulsion test data. This rewritten overview reorganizes those points for aircraft builders, integrators and maintenance teams while preserving the source-derived specification values for the selected KV450 winding.\u003c\/p\u003e\u003cp\u003eThe manufacturer information highlights dynamic-balance control intended to reduce vibration; a long-shaft layout designed for fixed-wing propeller installation. These features support dependable propulsion integration, but the motor must still be evaluated as part of a complete system. Airframe mass, aerodynamic drag, propeller diameter and pitch, battery voltage, ESC current capacity, cooling airflow, altitude and mission duration all influence the real operating margin.\u003c\/p\u003e\u003cp style=\"margin: 0; padding: 0; line-height: 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0750\/8112\/2008\/files\/UNITED-UAV-tmotor-at4130-long-shaft-fixed-wing-motor-description-01.webp?v=1790246895\" alt=\"UNITED UAV T-MOTOR AT4130 fixed-wing motor description image 1\" loading=\"lazy\" style=\"width: 1800px; max-width: 100%; height: auto; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\u003cp style=\"margin: 0; padding: 0; line-height: 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0750\/8112\/2008\/files\/UNITED-UAV-tmotor-at4130-long-shaft-fixed-wing-motor-description-02.webp?v=1790246895\" alt=\"UNITED UAV T-MOTOR AT4130 fixed-wing motor description image 2\" loading=\"lazy\" style=\"width: 1800px; max-width: 100%; height: auto; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\u003cp style=\"margin: 0; padding: 0; line-height: 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0750\/8112\/2008\/files\/UNITED-UAV-tmotor-at4130-long-shaft-fixed-wing-motor-description-03.webp?v=1790246896\" alt=\"UNITED UAV T-MOTOR AT4130 fixed-wing motor description image 3\" loading=\"lazy\" style=\"width: 1800px; max-width: 100%; height: auto; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\u003ch2\u003eFixed-Wing and VTOL Propulsion Role\u003c\/h2\u003e\u003cp\u003eThe AT4130 is designed for aircraft that need efficient forward-flight propulsion, VTOL pusher power or sustained heavy-lift operation, depending on the original series. The source lists Φ50*79mm, a motor weight including cable of 408g, and a 12N14P magnetic configuration. Use these values to confirm mounting clearance, center-of-gravity impact, cooling access and the structural load at the firewall or motor mount.\u003c\/p\u003e\u003cp\u003eFor a fixed-wing installation, verify thrust-line alignment, shaft clearance and propeller-to-fuselage spacing. For VTOL aircraft, consider the transition between hover and forward flight as well as the pusher motor's airflow during low-speed operation. A motor that is well cooled in cruise can run hotter during ground tests or slow transition phases, so temperature checks must cover the complete mission profile.\u003c\/p\u003e\u003ch2\u003eKV, Voltage and Electrical Matching\u003c\/h2\u003e\u003cp\u003eThis product is the KV450 winding. KV represents approximate unloaded speed per volt and should not be treated as a direct payload or thrust rating. The source associates this version with 6S, 75A, 1800W and an internal resistance of 16.8mΩ. Those figures provide boundaries for component selection, not permission to operate continuously at the maximum values.\u003c\/p\u003e\u003cp\u003eUse the source performance data and recommended component limits as the starting point for a propulsion match. Confirm that the battery can supply the expected current without excessive voltage sag, that the ESC supports the selected cell count and duty cycle, and that the propeller remains within the motor's mechanical and thermal capability. Different KV versions of the same motor body can require different batteries, ESC settings and propellers, so data from another winding should not be substituted.\u003c\/p\u003e\u003cp style=\"margin: 0; padding: 0; line-height: 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0750\/8112\/2008\/files\/UNITED-UAV-tmotor-at4130-long-shaft-fixed-wing-motor-description-04.webp?v=1790246895\" alt=\"UNITED UAV T-MOTOR AT4130 fixed-wing motor description image 4\" loading=\"lazy\" style=\"width: 1800px; max-width: 100%; height: auto; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\u003cp style=\"margin: 0; padding: 0; line-height: 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0750\/8112\/2008\/files\/UNITED-UAV-tmotor-at4130-long-shaft-fixed-wing-motor-description-05.webp?v=1790246895\" alt=\"UNITED UAV T-MOTOR AT4130 fixed-wing motor description image 5\" loading=\"lazy\" style=\"width: 1800px; max-width: 100%; height: auto; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\u003cp style=\"margin: 0; padding: 0; line-height: 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0750\/8112\/2008\/files\/UNITED-UAV-tmotor-at4130-long-shaft-fixed-wing-motor-description-06.webp?v=1790246895\" alt=\"UNITED UAV T-MOTOR AT4130 fixed-wing motor description image 6\" loading=\"lazy\" style=\"width: 1800px; max-width: 100%; height: auto; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\u003ch2\u003eMechanical Installation\u003c\/h2\u003e\u003cp\u003eInspect the mounting face, shaft, bearings, fasteners and leads before installation. Use screws of the correct diameter and length so they cannot touch the windings. The mounting surface should be flat and rigid, and the motor should rotate freely without rubbing or axial binding after the fasteners are tightened. Protect wires from sharp composite edges and provide strain relief where vibration or control-surface movement could flex the cable.\u003c\/p\u003e\u003cp\u003eBalance every propeller and adapter before full-power use. Even a small imbalance can increase bearing load, reduce efficiency and introduce vibration into autopilot sensors, cameras and payload instruments. Confirm the required rotation direction before fitting the propeller, then follow the propeller manufacturer's retention and torque guidance. CW and CCW are offered here as catalog options; both retain the same source motor specification, price and inventory policy.\u003c\/p\u003e\u003ch2\u003eGround Testing and Thermal Margin\u003c\/h2\u003e\u003cp\u003eCarry out the first test with the aircraft restrained and the propeller area clear. Increase throttle in steps while recording voltage, current, RPM, vibration and motor or ESC temperature. Compare the readings with the manufacturer's published limits and stop if current rises unexpectedly, the motor makes abnormal noise or the system develops excessive vibration. A short bench test cannot by itself validate a long climb, repeated VTOL transition or high-temperature mission.\u003c\/p\u003e\u003cp\u003eLeave practical reserve for battery sag, high ambient temperature, reduced air density and component aging. After the first flights, inspect the motor mount, propeller hardware, cable insulation and connectors, then compare temperatures between equivalent motors on the aircraft. One unit that runs noticeably hotter or draws more current may indicate a damaged propeller, alignment error, bearing problem or electrical fault.\u003c\/p\u003e\u003cp style=\"margin: 0; padding: 0; line-height: 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0750\/8112\/2008\/files\/UNITED-UAV-tmotor-at4130-long-shaft-fixed-wing-motor-description-07.webp?v=1790246895\" alt=\"UNITED UAV T-MOTOR AT4130 fixed-wing motor description image 7\" loading=\"lazy\" style=\"width: 1800px; max-width: 100%; height: auto; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\u003cp style=\"margin: 0; padding: 0; line-height: 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0750\/8112\/2008\/files\/UNITED-UAV-tmotor-at4130-long-shaft-fixed-wing-motor-description-08.webp?v=1790246896\" alt=\"UNITED UAV T-MOTOR AT4130 fixed-wing motor description image 8\" loading=\"lazy\" style=\"width: 1800px; max-width: 100%; height: auto; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\u003cp style=\"margin: 0; padding: 0; line-height: 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0750\/8112\/2008\/files\/UNITED-UAV-tmotor-at4130-long-shaft-fixed-wing-motor-description-09.webp?v=1790246895\" alt=\"UNITED UAV T-MOTOR AT4130 fixed-wing motor description image 9\" loading=\"lazy\" style=\"width: 1800px; max-width: 100%; height: auto; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\u003cp style=\"margin: 0; padding: 0; line-height: 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0750\/8112\/2008\/files\/UNITED-UAV-tmotor-at4130-long-shaft-fixed-wing-motor-description-10.webp?v=1790246896\" alt=\"UNITED UAV T-MOTOR AT4130 fixed-wing motor description image 10\" loading=\"lazy\" style=\"width: 1800px; max-width: 100%; height: auto; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\u003ch2\u003eOrdering and Maintenance Notes\u003c\/h2\u003e\u003cp\u003eThis listing separates the source page into an independent AT4130 KV450 product so the winding, SKU, price and Specifications tab remain clear. Shopify product weight is taken from the manufacturer's Motor Weight (Incl. Cable) value and converted to kilograms. The selected shipping package follows the approved store rule based on that motor weight and is not the same as any separate package-weight value shown by the manufacturer.\u003c\/p\u003e\u003cp\u003eBefore ordering, compare the source-derived dimensions, voltage, current, power and propulsion recommendations with the planned aircraft. Maintain the motor by checking bearing play, rotor condition, fastener security, lead abrasion, connector discoloration and changes in no-load sound or current.
