HECO Micro Servos
HECO builds compact servos aimed at small electric models, park flyers, and lightweight indoor aircraft where every gram counts. This category collects the HECO micro and sub-micro range along with a matching digital option.
Micro and Sub-Micro Options
The lineup includes the HES-540 micro servo, the HES-788 and HES-888 micros, and the smaller HES-988 sub-micro for the tightest installations. The HECO 440 uses a plastic gear train and comes with a JR and universal compatible connector, making it easy to plug into common receivers.
Digital Choice
For builders who want tighter centering and holding, the HECO HDS877MG is a digital micro servo. Digital servos update their position more frequently than analog units, which can sharpen response on control surfaces.
Across the range, these small servos are sized for the wings and tail of foam and light balsa models, so fitting them in a shallow bay or a thin control surface is straightforward. Check the connector and lead length against your receiver before installing one.
Compare the servo sizes below and choose one that fits your model's mounting bay.
