I used 1/8 carbon fiber on the ailerons and 5/32 on elevator (one side I used 4/40 rod 'cause was too short for the carbon fibre tube and titanium ends - from Central Hobbies) and went with pull/pull on the rudder (mounted servo on bottom of fuse as others did in previous posts). Works great for me. I'm flyin' with a now troublesome (2 deadsticks yesterday) Saito 1.00, 16x4 APC, S9202 servos.
