Properly Setting up a Pull Pull rudder?????
I was wondering if anyone had an article on setting this up properly? I know some dual servo arms come with an offset, but I've never really understood the theory behind it. I'm sure it's fairly simple but if anyone can explain how to set it up (for maximum efficiency, minimum slop) I would appreciate it!
I'm assuming the servo arm should be the same distance across as the control horns on the rudder (so if you are using a 2 1/2" arm then it should be 2 1/2" from horn to horn). What does the offset on the dual arm accomplish?
Thanks
