Product type Propeller Balancer Overview A precision propeller balancer in durable aluminium alloy, designed for hobby and light commercial model aircraft. It helps identify and correct static imbalance in propellers to reduce vibration and improve overall flight smoothness. Key benefits Accurate balancing: Provides a stable platform to detect heavy spots on propellers, making balancing straightforward and repeatable. Durable, lightweight construction: Aluminium alloy body resists wear while remaining light enough for bench use and transport. Broad compatibility: Works with multicopter and fixed wing models in the 250 to 700 size range. Fits shafts or adapters with diameters from 2 to 5 mm. Simple to use: Mount the propeller, rotate to find the heavy side, then correct with lightweight tape or sanding. No complex setup required. Reduces vibration related issues: By allowing precise static balancing, it can help reduce vibrations that contribute to motor and airframe wear and noisy operation. Features and specifications Type: Propeller balancer Material: Aluminium alloy Compatibility: Multicopter and fixed wing aircraft, 250 to 700 class Suitable for shaft or adapter diameters: 2 to 5 mm Function: Static propeller balancing to locate heavy spots and assist in weight correction Practical use scenarios 1) Preflight maintenance for a 250 class racing quad: Quickly check and balance replacement props before each event to help achieve smoother throttle response and reduce inflight vibration. 2) Build and setup of a 500 to 700 class fixed wing model: Balance newly mounted props during final assembly to minimize airframe vibration and sensor error during flights. 3) and refurbishment: After prop damage or repainting, verify balance to restore consistent thrust and reduce strain on motors and bearings. How it solves common problems Detects imbalances that cause vibration, enabling targeted corrections rather than trial and error. Compatible with a wide range of small to mid size models and common shaft diameters, reducing the need for multiple tools. Sturdy aluminium construction provides a reliable, long lasting tool for workshop and field use. What to expect in use Mount the propeller on the balancer, let it find its resting position, identify the heavy side, then apply corrective weight or remove material until the propeller remains level. The balancer is intended for static balancing tasks typical of hobby and light professional model aircraft maintenance. Package note Tool only.
