CTE

[Atwood, Mark]

I also use Coated steel fishing line...but I've never used anything but 20#.  What kind of tension are you guys putting on your rudder????  

Somehow I don't see my servo pulling 20lbs....meaning that my servo is going to give out LONG before my cables...

I use nylon-covered steel fishing leader.  I normally use 40# and I've 
never used stronger than 60#.
