Frequently Asked Questions

• Is the FMS PREDATOR KV1550 motor suitable for my 800mm Zero V2 aircraft? — Yes, this is the official FMS replacement motor designed specifically for 800mm Zero V2 aircraft. It features the long shaft configuration and KV1550 specification that perfectly matches the aircraft's power requirements and mechanical design.
• What battery does this motor need to operate? — This motor is designed to work with 7.4V 1300mAh 20C LiPo batteries featuring JST connectors, though it can handle higher-capacity 2S or 3S LiPo configurations depending on your ESC and power system setup. Always ensure your battery, ESC, and motor are properly matched for safe operation.
• What ESC rating should I use with this motor? — A 20A Electronic Speed Controller is recommended for the KV1550 motor in 800mm aircraft applications. This rating provides appropriate current handling for smooth throttle control and efficient power delivery without overheating.
• Can I use this motor as a replacement in my existing 800mm Zero V2? — Absolutely. If you're replacing a damaged or worn-out motor in your existing aircraft, this genuine FMS part will install directly into the motor mount with no modification required. Simply disconnect the old motor, install the new one, and you're ready to fly.
• What makes the long shaft design important? — The extended shaft provides flexibility in motor mounting position and helps achieve proper weight distribution and centre of gravity on your airframe. This is crucial for stable, predictable flight characteristics in scale aircraft.
• Is this motor suitable for beginners? — Whilst the motor itself is reliable and beginner-friendly, 800mm Zero V2 aircraft are intermediate-level projects. Beginners should ensure they have experience with aircraft assembly, proper battery handling, and RC radio operation. Using the FMS Reflex V3 stabilisation system is highly recommended for new pilots.
• What is the difference between this motor and similar alternatives? — This is the official FMS OEM motor designed and tested specifically for 800mm Zero V2 aircraft. As a genuine manufacturer's part, it guarantees perfect compatibility, correct performance characteristics, and alignment with your aircraft's engineering specifications. Aftermarket alternatives may vary in KV rating, shaft length, and performance characteristics.
• How long will this motor last? — Brushless motors like the KV1550 typically offer extended operational lifespan compared to brushed motors. With proper maintenance, regular inspection of internal bearings, and correct storage in dry conditions, you can expect many flying seasons of reliable service.
