Customer Questions & Answers

Question: What is the E-flite 3900Kv Brushless Motor used for?

Answer: The E-flite 3900Kv Brushless Motor is primarily designed for use in RC helicopters, providing power and performance for both hobbyists and enthusiasts. Its high KV rating indicates a rapid rotation speed, making it suitable for acrobatic maneuvers and improved responsiveness in flight. Additionally, this motor is compatible with various models, allowing users to enhance performance with better thrust and efficiency.
Question: Is the E-flite 3900Kv Brushless Motor suitable for all helicopter models?

Answer: While the E-flite 3900Kv Brushless Motor is designed for specific helicopter types, it is not universally compatible across all models. It's essential to check compatibility with your helicopter’s specifications, particularly regarding size, weight, and required KV rating. Many enthusiasts find this motor particularly effective in lightweight 450-class helicopters, improving flight characteristics and control during operations.
Question: What are the benefits of using a brushless motor like the E-flite 3900Kv?

Answer: Brushless motors, such as the E-flite 3900Kv, offer several advantages over traditional brushed motors, including higher efficiency, longer lifespan, and reduced maintenance needs. The absence of brushes means less friction, improving overall performance and allowing for higher RPMs. Additionally, these motors generate less heat, which can enhance flight times and reliability during demanding aerial maneuvers.
Question: How do I install the E-flite 3900Kv Brushless Motor in my helicopter?

Answer: Installing the E-flite 3900Kv Brushless Motor typically involves a few straightforward steps. First, ensure your helicopter is powered off and disconnected. Remove the old motor by unscrewing it from the mount, and carefully detach the wiring harness. Next, position the E-flite motor in place, aligning it with the mount, and secure it with screws. Finally, reconnect the wiring to your ESC (Electronic Speed Controller) according to the manual's guidelines to ensure proper functionality.
Question: What ESC is recommended for the E-flite 3900Kv Brushless Motor?

Answer: For optimal performance with the E-flite 3900Kv Brushless Motor, pairing it with a quality ESC that can handle the motor's specifications is essential. Look for an ESC rated for at least 30A to provide adequate current supply. It's also advisable to use an ESC with a built-in BEC (Battery Eliminator Circuit) to ensure that your receiver and servos receive a consistent power supply, enhancing the overall reliability and performance of your helicopter.
Question: What type of batteries should I use with the E-flite 3900Kv Brushless Motor?

Answer: The E-flite 3900Kv Brushless Motor is best powered by LiPo batteries, particularly those rated between 3S and 4S, which provide the right voltage for optimal performance. Using a 3S battery (11.1V) is common for balancing power and flight time, while a 4S battery (14.8V) can deliver higher performance, resulting in faster speeds and stronger climbs. Always ensure the battery’s C-rating matches the demands of your heli for safe and effective operation.
Question: Can I use the E-flite 3900Kv Brushless Motor for aerobatic flying?

Answer: Yes, the E-flite 3900Kv Brushless Motor is an excellent choice for aerobatic flying due to its high RPM and responsiveness. Its design allows for quick accelerations and dynamic maneuvers, making it ideal for performing tricks such as rolls, flips, and loops. Hobbyists appreciate the motor’s ability to maintain control during agile movements, enhancing the overall flying experience and enabling more advanced flight techniques.
Question: Does the E-flite 3900Kv Brushless Motor require special maintenance?

Answer: The E-flite 3900Kv Brushless Motor requires minimal maintenance compared to brushed motors. Regularly check and clean the motor and its components, especially the connectors and mounting points, to prevent dust and debris buildup. The bearings may require lubrication occasionally, depending on usage, to ensure smooth operation and longevity. Also, inspecting the wiring for wear can help maintain efficiency and reliability.
Question: Where can I buy E-flite 3900Kv Brushless Motor BSR EFLH1516 Replacement Helicopter Parts in New Zealand?
