Thank you everyone for your responses.
Lone Star Charles, as guver stated I prefer to learn how to choose so the calc you posted is a very good thing.
On the 60, I am concerned about the space to mount two servos. My thinking is that if one 40 oz/in standard servo is sufficient for two ailerons then one 20 oz/in servo should be sufficient for one aileron. If I end up needing two High Torque mini/micros then that is what I'll get but if they are not needed then I prefer to spend that extra $$ elsewhere. Once the plane arrives (an ARF supposed to get here Tuesday) I'll be able to measure it up and see. It's a trainer from Tower. I don't plan to use the flaperons right away but am trying to plan ahead as I know it's easier to build something like that in initially rather than modify later. I've read several threads on flaperons and found nothing definitive so I thought I'd leave the option open to myself to experiment with later.
Jester I do need to post some photos of that sailplane. I thought it was a Gentle Lady but it is not like the kits shown now and it has spoilers. I built it while in my teens, during the early '80s.
Guver I don't mind at all as you were correct in your thinking. Hopefully someone will help us out here.
