\\ servo case is now full metal! //　
Best servo for E-IMAC and Jets.up to 85”3D
 
Stall Torque 26.5Kgf・㎝
The JR standard size servo S8411 series is now available in a full metal case, the V2.
The case rigidity has been further improved for smoother gear rotation.
In addition, a potentiometer and 2K firmware from a Japanese manufacturer have dramatically improved the servo's performance.
This servo is suitable for everything from sports flight to precision (30 to 50cc class).
About the servo horn
In order to maximize the performance of the high-torque servo, the servo horn should be made of
We recommend using “JR Genuine Metal Servo Horn” or “JR HD Horn” for the servo horn to maximize the performance of the high-torque servo.
If you use JR compatible servo horns made by other companies, the servo may be too loose.
Also, in order to maximize the performance of the servo, the length of the horn should be as short as possible,
If the rudder angle is not enough, please adjust the travel adjustment wider or change the servo movement angle to “150°” in the XBUS setting.
If the rudder angle is not enough, please change the servo movement angle to “150°” in the XBUS setting.
Initial Parameter Value Setting
The initial parameter values of this product are set for 50cc class airplanes.
If the rudder used is light, hunting is likely to occur.
Please change the following items in the XBUS settings to the optimum values that do not cause hunting.
［XBUS setting items]
HOLDING/Holding force: +5 max.
DUMPING/stopping characteristics: +30 max.
