I just bought a morris 3d profile plane with pull pull rudder and elevator ( so - do - somthin or other??? ). ( I'll put my OS .55 on it which is at the top end of its power rating)
I already installed the control horns on the elevator and rudder, the holes are about 1/32" behind the hinge line. ( is that ok? )
Any tips or things to watch out for on the pull pull set up?

Looks like one end just loops through the servo and has a single crimp. Just squish with plyers?
Should I but a drop of CA on the crimp? Its very thin cable with a plastic coating...



Does pull pull put any more strain on the servo? should they be ball bearing? nylon gears alright?
I plan on pulling 2 servos out of old equipment, is there a way to tell the condition of a servo?
Which servos would be the most critical?

throttle - used
rudder - used
elevator - buy new
aileron - buy 2 new

thanks
