The LN1103 is a high-performance 1103-class micro brushless motor from the Badass series, designed specifically for racing applications. It offers a lightweight design and high burst power, making it suitable for 2–3-inch micro RC cars and an ideal power option for short-wheelbase racing platforms.
Product introduction
Its key strengths lie, first and foremost, in its extreme lightness and exceptional thrust-to-weight ratio. Weighing just 4.3g, the motor delivers powerful thrust whilst significantly reducing the overall weight of the aircraft, maximising the thrust-to-weight ratio of short-wheelbase models. Whether it’s aggressive acceleration, sharp turns or high-speed manoeuvres, it offers pinpoint control that perfectly suits the intense pace of competitive racing.
Secondly, it strikes a balance between aggressive power delivery and consistent output. Optimised specifically for 2–3S lithium battery systems, its high-RPM characteristics are perfectly matched to 2-inch propellers. Throttle response is extremely quick, with virtually no lag, allowing for instant power delivery to meet the demands of frequent full-throttle manoeuvres during competitive flight. At the same time, the low internal resistance design effectively controls heat build-up under high loads, ensuring stable performance even during prolonged aggressive flying and preventing power loss due to overheating.
Featuring a 9N12P slot-pole configuration, it operates smoothly with minimal vibration. Combined with a robust shaft system and a reliable mounting design, it can easily withstand the frequent starts and stops and intense vibrations typical of racing scenarios, offering maximum durability and minimising the likelihood of faults. The mounting holes are compatible with mainstream micro-chassis, ensuring excellent adaptability and straightforward setup and tuning. Whether you’re a beginner taking your first steps in racing or an advanced player looking to improve your lap times, you’ll be able to quickly harness its performance advantages.
Overall, the LN1103 combines lightweight construction, high torque and excellent stability to offer a reliable yet powerful power solution for mini racing RC cars, making it an unmissable choice for enthusiasts seeking speed and manoeuvrability.
