Frequently Asked Questions

What is the compatible voltage range for the SPEEDX2 2105.5 3450KV motor?

This motor is officially rated for 3S to 4S LiPo battery systems (approximately 11.1V to 16.8V). Its 3450KV winding is optimized for this voltage range to deliver high RPM and explosive torque without exceeding thermal limits. Do not use it on 5S or higher voltage packs as this may lead to overheating and premature failure.

What propeller size and mounting does this motor support?

The SPEEDX2 2105.5 motor is designed for 3-inch to 5-inch propellers. It features a standard 1.5mm outer shaft diameter, compatible with most propellers using a M5 nut. It mounts to frames using M2 screws on a 12mm x 12mm hole pattern, which is common for many modern 20x20mm and 25x25mm FPV stack configurations.

Is this motor suitable for long-range or freestyle FPV drones?

Yes, its 21g lightweight design and efficient power delivery make it an excellent choice for both applications. For freestyle, it provides the instant torque needed for tricks, while for long-range, its efficiency on 3S-4S helps maximize flight time. Ensure your Electronic Speed Controllers (ESCs) can handle the motor's peak current draw of up to 34.9A for reliable performance.
