Well, never heard that a servo working on sine wave input, what was it? I would like to learn something about their working theory. Thanks!

Futaba S148???? are you kidding or want to fool me? I have one and it is working on Pulse width signal control , a standard of existing servos on the market nowaday, centre pulse width is 1.52ms. Do you really understand what is Sine wave signal?
here is the link for S148 specfications:

Thanks!

Oh, mine was not that old, its around 15 years old but still working. I only know it was a early version of the S3001 which has 1 BB and has exactly the same specifications. I really want to know how it (yours very old S148) works with sine wave signal input.
BTW was there any receiver has sine wave signal output to servo? Any brand name you like to mention?
thanks a lot!

Yea, I know, I still recall my first RC equipment was a Futaba 27Mhz 4ch AM and all the servos were of 3 pin male. I also DIY home make my own RC equipment , a 8ch 27Mhz AM transmitter and receiver from discreted parts when I was still a Form 3 student. But at that time the servos were running on pulse width control signal so called the digital proportional system already. So thats why I am so surprise that there were some other system running on "Sine wave signal"??? and really want to learn somethings from you.
Thanks!
