“As long as they work and the insulation isn't brittle on the wires. The 148 was the standard futaba servo for a long time. They are still in production but they have a few newer choices now. I would set them up and run them back and forth for a few minutes before you install them in a plane. Use it on the throttle and you minimize the risk even if it does fail.-- “

“ The S148 was, and still is, Futaba's cheap throwaway servo. As long as it's not expected to do much, it'll be fine.”

“ Mhhh, you mean the S3003 is the cheap, throwaway servo. 

The 148 is a very good servo, mine have outlasted the 3003 by far long....

The 148 is "almost" a S3001.”

“ The S148 is a very good servo, probably the best in its price class. I have used them on even 1/4 scale planes with great success. They will hold up to vibration better than most regardless of price. “
