The discontinued Flyermate A3.7 is a feather-light analog pico servo, designed to provide a reliable and extremely cost-effective solution for the lightest of RC aircraft. True to the Flyermate brand name, this 3.7-gram servo is all about getting small electric models airborne with minimal weight and minimal cost. It is the perfect choice for indoor "living room flyers", small park-flyer foamies, and other highly weight-sensitive projects. The A3.7 provides the basic, smooth proportional control needed for these low-stress applications, making it a favorite among scratch-builders and hobbyists who enjoy experimenting with micro designs.
The core identity of the Flyermate A3.7 is its incredible value and accessibility. It is one of the most inexpensive ways to add control to a micro-sized project, making the hobby more accessible to beginners and more sustainable for builders who go through a lot of components. It provides the essential function of motion in a tiny, feather-light package, without any unnecessary frills or costs.
For students, makers, and robotics hobbyists, the Flyermate A3.7 is a fantastic tool for learning and creating on a budget. Its extremely low cost makes it feasible to build complex, multi-servo robots, such as a small insect-inspired walker, that would be prohibitively expensive with premium servos. It is an essential component for any creator who is working in the micro-scale on a tight budget."
