Hi J.Paul,
Yes, the information in your link is correct the torque at 4.8V for the S3010 is 72.2 oz-inches.
Using 4.8 volts with this servo will not harm it or your plane.
I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
Sincerely,
Krysta
