First time using a pull pull and got this question:

I've got the rudder end set up no problem. At the servo end, instructions say to "ensure the cable is the correct length". What with the "loop de loop" that the cable does going through the clevis holes and that little brass sleeve, how do you ensure that after the cable loop is tightened, the cable is in fact the correct length?

Would you attach the clevis to the horn then thread the cable etc etc?

Obviously my concern at this point is that I could measure the cable and loop it so the clevis reaches the horn but how do I ensure that after the loop is tightened that the cable is STILL the correct length?

Thanks.
