Servo Linkages

[derekwarner_decoy]

Hi PD's & a question for Dan [Sparger] - just resolved my viewing issue after many months Dan & got to view your snaps this evening which look great

'paddle_wheel_project_014' snap shows three 'SUL' brand non swiveling type servo linkages for the monkey rudders - I had not considered this style of linkage & have pre purchased six ball & nylon cap style for rudder/steam control/reversing gear linkages for PS Decoy

So my question is 'are the non swiveling type servo linkages more reliable or firm than the ball & nylon socket style?' as the attachment to the Stephenson steam reversing gear when set must not float or drift after the set points are achieved etc

Any thoughts or comments appreciated - Derek

Hi Derek,

Noticed your post re the SUL type linkages. I've used those linkages on a twin schottel drive tug boat and found them very very good - easy to clip on and off, no slack and the threaded rod means that they are infinitely adjustable for fine tuning. They have a nice discrete shape as well - not perhaps as obtrusive as the ball and socket approach.

The only negative that I've heard is that one should avoid unshielded or ungrounded metal on metal movements in an R/C environment as these can induce radio interference - I can't imagine that the small movements involved in controlling rudders would be that troublesome but who am I to say! The ball and nylon socket approach certainly overcomes that concern.
