The right size and strength for every application!
You don’t have to be a top R/C competitor to appreciate the performance and reliability of Futaba servos — those same qualities plus their economical cost makes them equally popular with everyday hobbyists. If digital servos are what you crave, look to Futaba for virtually instantaneous response, near-perfect resolution and gears just short of indestructible. The result of extensive research, testing, and cutting-edge construction, Futaba's digital servos offer higher torques and faster rotational speeds for improved model performance and no increase in size and weight.
Use the charts below to choose the best servo for your application from over fifty analog and digital styles, ranging from the 0.23 oz. S3111 Micro Servo to the mighty S3306...with over 300 oz.-in. of torque!

High-Performance Digital Servos |
- Surface Mount Technology (SMT) and heavy-duty output shafts add dependability in high-vibration applications.
- Impact-resistant cases withstand minor crashes and the caustic effects of model fuel.
- "Through-the-hole" circuit board plating eliminates the need for wires or leads.
- Many take advantage of the latest developments in coreless motor design for improved resolution.
- Look for servos with single or dual ball bearings for smoothness.
- Options include servos with precision-ground metal gears with a special, interference-eliminating lubricant for maximum strength.
- Water-protected servos are available for marine applications.
- Great options for every application from the smallest micro/mini to the largest giant-scale airplane.
Several Futaba Analog Servos feature precision-ground metal gears with a special lubricant that eliminates interference for maximum strength. |

- The microprocessor sends pulsed power six times faster to the motor, for response that’s up to 50% quicker.
- Response is appreciably smoother due to each signal-to-move being broken into six smaller, easier steps.
- Faster pulse rates hold a precise setting over time.
- Extra-tight tolerances and digital precision enable servos to come back on-center with enviable ease and incredible accuracy.
- Updated gear train technology allows resolution to start at premium levels and stay there.
- Gears not only stay in-mesh longer, they last longer and cost less to replace.
- Digital servo gear weighs less, meaning less mass for the motor to move for enhanced response.
Each Futaba Digital Servo includes a built-in, quartz crystal-controlled microprocessor, along with an FET (Field Effect Transistor) that further amplifies the signal. |

| Brushless Servos |

Compared to brushed motors, brushless motors offer twice the efficiency, require virtually no maintenance and last longer as well. Futaba has blended brushless benefits with digital design to create three cutting-edge servos. The results are incredible. They center/hold/respond as quickly and precisely as brushed digital servos and last up to five times longer. They’re more shock and vibration-resistant and run cooler, too. (No brushes mean no spark (and no heat), plus the motor’s outer coils act as a heat sink.) And since they’re the size of most standard servos, you can upgrade for more torque or speed without worrying about space. The BLS251 is a fast 4.8V servo for heli rudders. The high-speed BLS351 and high-torque/high speed BLS451 are all-purpose servos for 4.8V or 6V use. |
