Servo options for CARF Extra 330L
 

I have one that I have yet to fly. I had disassembled it to use the servos in another plane, they are JR 8411 and 8611. So far I have had two of them wack out where one jotters, and another just moves 90* after moving both ways a couple times. I want to do some shopping to keep the costs down since there are 8 servos in this plane plus the throttle, so knowing what brands/models to look for would be most helpful.
