I'll throw in another vote for the 5955's. I've tried many Futaba and Hitec servos and they all seem to get sloppy which cause some to bounce/jitter at center. I tried one 5955 on the giant rudder on my Vision and it's solid after 50+flights. NO slop NO jittering. Full throttle 3D snaps all day long and no slop!

You can get them for under $100 on sale. I've only tried one but if they are all this good, why buy anything else
