RC Servos & Servo Spares

RC Servos for Helicopters, Planes and Cars

A servo turns the signal from your receiver or flybarless unit into precise movement, driving steering, throttle, control surfaces and helicopter swashplates. We offer servos in a range of sizes, from sub-micro linear servos for indoor planes to brushless jumbo servos for 1/5 scale cars.

Choosing a servo

• Size: browse Micro, Mini, Standard and Jumbo servos to match the servo pocket in your model.
• Torque: quoted in kg (kg.cm) – use the Torque kg filter to find the strength you need. Heavier models and larger control surfaces need more torque.
• Voltage: HV servos run direct from a 2S LiPo (7.4–8.4V); 12V servos take higher voltages again. Standard servos run at 4.8–6V.
• Speed and motor: coreless and brushless servos are faster and more precise – ideal for helicopter cyclic and tail, racing cars and 3D planes.
• Gears: metal, steel and titanium gears handle crashes and high loads better than plastic.
