January 1, 2025Application(s): ailerons, ruder, and elevators for model airplane
Comments: Very smooth running servo. Good for a small airplanes. Tested against other brands with full sweep left and right. Movement is opposite SG90 servo.

July 28, 2022Application(s): Was used to test with arduino and as a power generator.
Comments: It works great but, the gears break and sometimes the whole gear system get stuck.

November 17, 2020Application(s): Learning Arduino
Comments: Came with the kit. It wouldn't quite get to the final position for any setting (1 or 2 degrees short each time). As a result it kept trying, causing a lot of vibration.
