I recently acquired a used 2.3 Comp Arf 330L.I am about to setup the rudder pull-pull.
I did not get the rudder pull-pull setup with the plane.The local hobbyshop has a Dubro 518 4-40
pull-pull cable set.Will this be strong enough for this plane?I am using Power HD 1501MG
servos at 6.0v.(236oz-in each).I am using 2 on the rudder.Can someone recommend a
pull-pull setup that will be stong enough if the Dubro is not.Also any tips on setting pull-pull up
will be appreciated.I have only did a few of these but not on a gas plane.Just want to get this setup properly.

Thanks Roy

This is how I did it.

4-40 pull-pull hardware will be fine. I do think a single 8711 or 7955 will be plenty of servo for this plane. You will probably want to use a bell crank of some kind to keep the cable tension off the servo itself.

That's a fine looking plane. The owner should be proud!

I have been using 1 ea JR8711 servo on rudder and its more than enough. I can make knife edge loops. I am using JR 8611A's on each aileron and elevator halfs , they have also enough power but 2 ea JR8411 for each aileron would be better for 3 d for this bird. Here are some pictures;
