The Low Profile Digital High Speed/Torq Servo produced by Futaba, is classified in R/C Models - System - Servo - Low Profile Servos
Here is the S9551 tall Torque Low Profile Digital Servo w/Coreless Motor for Aircraft and automobile Use. FEATURES:
- Digitally improved microprocessor cuts approximately half for the reaction time from transmitter input to servo response
- Low profile permits the servo to fit into wings and lay down in car chassis at a lower price obstruction
- Coreless engine
- Metal gears
- Twin ball-bearings
- Black synthetic situation
- Dust and waterproof (not waterproof)
- Ideal for F3A aileron application and 1/10 scale electric touring car

RESPONSES:
S9551 Digital Servo Precautions, it is advisable to avoid long leads and Y-harnesses particularly with standard grade wires. If problems are encountered, consider using heavy weight cable particularly Futaba's Heavy Duty Series or Hobbico's Pro Series, minimizing lead lengths, and/or the removal of Y-harnesses. Current Drain: Futaba S9551 Servo is specifically made for tall- Torque and High-Speed, Therefore Very High Current Drain Is Normal At Business. For Ultimate Efficiency Whenever Making Use Of This Servo, Please Review The Next Points. (1) When Utilizing Techniques With all the Battery Fail Safe Function this has an increased Cut-Off Voltage establishing That May Cause Shorter Procedure Time. (2) When Setting Up the Servo Please Check always Pushrod Linkage To Ensure There Is Absolutely No Binding to be able to Prevent Excessive Power Consumption and Decrease the Life associated with Motor and Battery.
This digital servo can't be used with the following * have always been * transmitters as the servo neutral signal is: 1310us). CONQUEST AM, FG Series (T4FG, T5FGK,T6FG, T6FGK, T7FGK), Brand New Terratop, T3EGX, T3PGE, T2NL, T2LGX, T2FR, T2PK show. For full performance usage with FM, PCM and HR systems.
An email on Coreless engines. A conventional servo engine has a steel core armature wrapped with with cable that spins inside the magnets. In a Coreless design, the armature uses a slim wire mesh that types a glass that spins across the exterior regarding the magnet eliminating the heavy steel core. This design is a lot lighter leading to smoother procedure and faster reaction time.
