Dbow,
Either the S3305's or S3010's would be a good choice for the rudder and elevator on this plane. They both have more torque than the S3004's and have good centering ability.
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
