S148 Servo Equivalent

[mwechter]

I am building a very old GreatPlanes J-3 Cub kit with a 75" wingspan that suggests Futaba S148 servers for the control surfaces.
Do you carry an equivalent servo?
I am planning on coming back to you for the (electric) motor, ESC, receiver, and new transmitter in a few weeks.

I knew Wayne when he lived in SoCal. Tell him and Jane that Michael and Randy say hi.

That is a low performance servo. Just about any modern 12 gram digital servo will do. As this is a kit I assume you can fit the servo mounts to fit any servo you choose.

Power, but the size and weight much smaller than the obsolete Futaba 148

Yep - Agreed - if you need the size, just about any standard sized servo will do the trick. But you should be able to get away with a smaller and lighter servo these days. Will save a bunch of money too!
