I am currently building the Colombo Anderson 27% Extra. I have 8101's that I was planning to use on the elevators and ailerons. I also have a 4721 that I was going to use on the rudder. I would like to know if you think these servos would be enough? I'm not into heavy 3D at this point.

Thanks,

My feeling is that would be a fine set up, but it is possible you may want more torque on the rudder to have the best rudder authority, but the 4721 may work fine.
