Frequently Asked Questions

Q: What is the SG90 MG90 mini servo used for in RC aircraft?

A: The SG90 and MG90 mini servos are small electromechanical devices used to control the movement of control surfaces — such as ailerons, elevators, and rudders — on fixed-wing remote-controlled aircraft and model planes. They convert electrical signals from your RC receiver into precise mechanical motion.

Q: What is the difference between the SG90 and MG90 servo types?

A: The SG90 typically features plastic gears, making it lightweight and ideal for lighter aircraft or beginner builds. The MG90 uses metal gears, offering greater durability and torque — a popular upgrade for more demanding applications or heavier control surfaces.

Q: Will this servo fit my RC aircraft or model plane?

A: This servo measures 23mm × 12.2mm × 29mm and uses standard SG90/MG90 sizing, which is compatible with the vast majority of fixed-wing RC aircraft frames and model kits available on the market. Always check your aircraft's servo bay dimensions before purchasing to confirm fitment.

Q: How many color options are available for this servo?

A: This mini servo is available in 4 color options, so you can choose the one that best matches your RC aircraft build or personal style preference.
