I am by no means an expert in pull-pull set ups. I have done a couple.
For me it's one of those start fresh kind of projects. I never fiddle with them at the end of an evenings work.
Every pull-pull I've done you cross the wires inside the fuse. Dubro makes some nice pull-pull attachments that I screw into ball links and bolt the ball links to the servo arm. Makes for a really nice clean set up.
When I thread the cable though the crimp I loop it back on itself so that if it ever slipped it locks on itself.
Here's a drawing of the way I loop my wire in this thread.
BTW, I ordered a new toy for next year.
I know you like the unusual so take a look at this.... I wont get to it till after flying season starts next year but I don't want to miss it. I've only seen it at one shop.
I'm hoping to see your fleet at out warbird day next year
