Hi DOORGUY1,
There is no programming required for digital servos. And any digitals should be fine in conjunction with your MSA-10. Some recommended servos for your 33% Ultimate would be the S3050, S3151, and S9252. Also you may want to look through some of our digital servos on our website at:

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
Lead Futaba Customer Service and Programming Technician
