Mainly Servos

The smallest class. Used in micro indoor fliers, tiny gliders, and sub-250g FPV. Limited torque — best for light control surfaces only.

Park flier and small fixed wing. Handles ailerons and elevator on models up to around 1m wingspan. Good balance of weight and torque.

Browse Micro →

Sport fliers and smaller surface vehicles. Common in RC cars for steering. Wide choice of torque ratings and metal gear options.

Browse Mini →

The most common class. Used in most RC aircraft and surface models. Wide range — from economy to high-speed digital competition servos.

Browse Standard →

For 1/4-scale and larger aircraft, scale warbirds, and big gliders. High torque at full throw. Often specified by servo arm angle requirements.

Browse Quarter Scale →

Large gas and turbine aircraft. Very high torque, robust gearing. Often paired with a separate BEC to handle the current draw.
