None of those are high performance jets, they will fly fine on standard cored servo's, if you have 60 + ounces of torque you should be fine. The stab on the F16 being full flying may need more, I'm sure somebody who's built one will chime in, but I have known many people that had the F16's and Mig and all used standard servo's. These jets were around in the days that 45 ounces of torque in a servo was a lot and flew fine.
