IanR Posted February 16, 2016 Share Posted February 16, 2016 When fixing a pushrod with a z-bend at one end and a clevis at the other end does it matter which goes on the servo arm and which goes on the control horn? Many thanks. Ian Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted February 16, 2016 Share Posted February 16, 2016 Only that it is easier to adjust thecontrol if the clevis is out in the open and nt buried in the model on the servo Quote Link to comment Share on other sites More sharing options...
Richard Wood Posted February 16, 2016 Share Posted February 16, 2016 Hi Ian, Usually Z bend at the servo & clevis at the control horn. Any adjustments can be easily made without needing to get access to the servos - no need to take wing off. Beaten by a quicker typer..

IanR Posted February 16, 2016 Author Share Posted February 16, 2016 That makes sense. Thanks to both of you. Ian Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted February 16, 2016 Share Posted February 16, 2016 It's also a damn sight easier to fit a servo horn onto a Z bend then onto the servo than it is to unscrew a control horn from an aileron/rudder/elevator surface to do so at that end.

IanR Posted February 16, 2016 Author Share Posted February 16, 2016 You're right, Bob. I've just done that. Thanks. Ian Quote Link to comment Share on other sites More sharing options...
ASH. Posted February 16, 2016 Share Posted February 16, 2016 The Z bend is the least desirable method for attaching rod to horn. The hole has to be larger than normal which causes slop. We are talking fractions of an mm but it is there when it needn't be. Far better to put a 90* bend in the last <10mm of rod and secure with plastic keeper at the servo end and clevis at the other. For a fast high-powered models I prefer 2mm ball joints threaded onto push rods for elevator and rudder.

Bob Cotsford Posted February 17, 2016 Share Posted February 17, 2016 I'm with Richard, if the holes are drilled a close fit there need be no more slop than with any other connector, and unlike the bend and keepers, there is 0% chance of anything becoming disconnected accidentally.
