Frequently Asked Questions
Q: What model aircraft are compatible with this 0.25g micro electromagnetic servo?
A: This micro servo is designed for DIY indoor model airplanes using 4mm or 6mm coreless motors — including nano and micro-class foam flyers, paper planes, and other ultra-lightweight RC builds where minimal weight is critical for flight performance.
Q: How does an electromagnetic servo differ from a traditional servo for RC models?
A: An electromagnetic (magnetic steering) servo uses a permanent magnet and brush-commutated gear motor to achieve directional control, making it far lighter and more compact than conventional servo designs. This makes it ideal for micro-scale aircraft where standard servos would be too heavy.
Q: Can I use this servo with motors other than 4mm and 6mm coreless motors?
A: This servo is optimised for 4mm and 6mm coreless motors. Compatibility with other motor sizes may vary — always verify motor diameter and electrical requirements before integrating into your build.
Q: How many servos come in a pack?
A: You can choose between a 1-piece, 2-piece, or 3-piece pack, making it convenient to buy exactly what you need for your current or upcoming DIY model projects.
