Futaba S5101 servos
 

I have several Futaba S5101 servos that I want to use in my airplanes, however, I am unable to identify the specs. I dont know if these are ball bearing, coreless, or their torque, speed, etc. Please help me to sort out what I have so that I may employ them properly. The case size is just very slightly smaller than the popular S3003 servo. I seem to have run into a dead end street on my own, so I thank you very much for your help.

How about
 

S5101 0.77 x 1.52 x 1.36 J 1.40 55.60 0.24/60

Replaced by S9001

Thanks for the info'
 

I see the S9001 listed as "coreless".
Is the older S5101 also a coreless servo?

Used them myself back a couple of years... Futaba pls correct me if I'm wrong, but I remember their specs as non coreless (cored) motors...they were very smooth though...I liked their lighter weight/smaller size.

Cheers,

Good morning KenChoo,

You are correct the S5101 is a "cored" motor. The smoothness that you notice is most likely from the Dual Ball Bearings that they have.
