CPLR used a low torque high speed on elevator not rudder, he ran the 9351 (as did most) on the rudder, which is a 200 in-oz .13 servo. Most have gone to this over the 9151 (130/.18 ish) as the higher torque servo improves the rolling circle and rolling loop common in the F schedules.

I dont think this is required unless you are doing those manuvers...100 inoz on rudder should be plenty for most...60-80 on ailerons and 50 on elevators (or dual 50's if you run dual elevators).

Personally I went 9351's on rudder and ailerons to minimize the number of different servos I have....this way I only need a single spare that will work in 3 spots....I use dual elevators so 9650's go on them.
