Pull-Pull set-up pics
 

Anyone using the coated pull-pull cable? I put mine on and can't crimp them where they wan't slip. any pics or help????[:o]

Perhaps you need to remove the coating before you crimp. Or maybe use fishing leader crimps. They have coated leader wire also and I've never seen one of those fail. Just a thought.

I use Kevlar that has no coating. After I crimp a drop of CA keeps things in plce for sure. Make sure the CA dosen't saturate a section of the Kevlar that needs to flex. Put a peice of heat shrink where it exits the fuse and call it done.

Eddie, nice rig. Can't go wrong with SWB. I agree with Shawn B. Although my cable is coated, I find that after the line is crimped all it takes is a drop of CA to lock it.

krayzc-RCU, interesting setup. Does the geometry of that set up offer more leverage than an inline rig? Thanks, Joe

I second that. I've even had the slippage problem on much smaller-scale planes, where you wouldn't think there was enough forces to cause it. CA alway took care of it. Nice setup by the way!!

cumn thru
this set up is a quick deal to not running into matching or binding issues. i can get enough throw for the needs. i am not sure what the max is i only do 40 degrees on all planes surfaces for 3d this bird has such a huge rudder and side fuse that is doesn't ever take much to do even a knife edge loop with this deal. a big bird always does makes things easier IMHO.....

no probs here...but the obvious would be loop the cables through the crimp twice..?

RE: Pull-Pull set-up pics
 

I secound on the 2 loop deal. I always loop the cable threw twice never had a problem with coated wire slipping with that method.

Thanks for all the help, I will try the ca and if that dont work I will get a new cable and run it thru twice. I realy like the SWB ...

How do you mount those SWB rudder control horns?

RE: Pull-Pull set-up pics
 

The control horns mount like any other to the servo output shaft. The nice feature with SWB is they now offer a 'duel lock' feature. The arm screws down like any other, but these have a split center with two additional bolts that go through and pinch the servo output shaft. Also the holes for linkage are pre threaded for 4/40 applications.

If your question pertains to the above rigs, the servo tray comes with cut outs for mounting more than one servo. It also comes with an attached bell crank to keep the tension of the cable, under load, off the servo itself. Offered with a straight arm for parallel runs or an offset arm for crossed cable configuration. The servo arms ar ganged together with short linkage and connected to the bell crank.

Here is a pic of a single servo, JR 8411 on a 10 lb. 2 meter plane. Didn't think it would need a tray and bell crank, but it would help extend the life of the servo. I used an offset arm for a crossed wire set up and a straight arm through the rudder. Joe
