【問題】請問各位先進: FUTABA SERVO 的問題

SAMU

ＦＵＴＡＢＡ的ＳＥＲＶＯ有的特別標示Ni-cd 4.8V專用, 例如：Ｓ９２５０, Ｓ９２０４,
請教各位先進, 是否可用Ni-MH 6V Batteries.

RC

6V可

建議不要 因現在的ＳＥＲＶＯ 已很快很有力了

SAMU

First of all, Thanks for your reply, RC.
Secondly, 用6.0V Battery 的理由是因為想要Rudder Servo (S9450)的速度;
我的System: Two S9204 for Aileron
                     Two S9250 for Elevator
                     One S9450 for Rudder & S135 for Throttle
So, Digital Servo and Csr Servo 的混用是否會有問題？

Thank you very much, again.

Futaba servo 9204

前些日子買了一顆9204,但一直拿不定主意該用4.8v or 6v
經詢問美國Fataba及日本Futaba總社,都建議用4.8v.原文如下,供各位參考
  
Dear Mr. Chang
Thank you for asking via Futaba web site.
  
S9204 is specially designed for high-torque, therefore very high current
drain is normal at startup.
If using dry-cells, there will be less performance and when using systems
with the battery fail-safe function, the operation time will be very short.
Please use it with a NICAD battery.
If using S9204 at 6.0V, the life of the servo is decreased extremely.
Please use it at 4.8V.

Dear Sir:
  
Thank you for your Email.
  
The Futaba S9204 servo, which is now discontinued was originally designed to be used with standard 4.8 V NiCd battery packs.  When it came out, 6V operation was not very common, so Futaba did not test it with 5-cell NiCd battery packs.  We don't know how it will hold up if you use such a pack.
  
Also, 5-cell NiCd battery packs can be as high as 7.5 V when fully-charged, with the voltage gradually dropping to 5.5 V, when the pack is depleted.  The higher voltages can cause damage to servos.
  
In short, we don't know how your  S9204 servo will fare with a 5-cell battery pack for power.  It's not been tested that way.
  
We hope you find this information helpful.  Should you have any further questions or concerns, please do not hesitate to contact us at this email address.  (Please be sure to copy all previous emails into any future questions.)

最主要的是  鎳鉻電池 對SERVO  PROWER  有很好的幫助   (電流比較大)
想一想為甚麼原廠均賣   鎳鉻電池--------------------
