For hobbyists flying small electric craft who need reliable, repeatable control, the Futaba S3156 is a compact, robust choice that fits tight layouts without sacrificing performance.

Is the Futaba S3156 suitable for lightweight foam park flyers?

Yes, the Futaba S3156 is sized and powered well for foam park flyers and other small electric planes where space and weight are limited.

What supply voltage gives the best performance?

Use a regulated supply between 4.8V and 6V. Running at 6V yields the highest speed and torque without exceeding the recommended limit.

Which servo horns fit this unit?

Standard micro servo horns are compatible; use horns sized for micro servos and check spline compatibility before fitting.

Any tips for mounting in tight bays?

Use low-profile mounting screws and trim surrounding foam or plastic clearance carefully. Secure wiring to avoid interference with control linkages.
