OK, maybe the FA-100 is "little" too big for this plane.

I have hs-605BB servos in both elevator and rudder. My aileron servos are between R-4 and R-5 ribs, so there shouldn't be too much loose in the pushrods, but maybe I change the servos to hs-225BB.

Which Irvine 72 or OS 61FX would be better for this plane? I know that there are CAP's that have Saito FA-91 in the nose and still flies just great.
