Phil 9 Posted August 27, 2017 Share Posted August 27, 2017 Fitting the closed loop system to a rudder on my acro wot. Should the wires run parallel or cross over Quote Link to comment Share on other sites More sharing options...

Keith Berriman Posted August 27, 2017 Share Posted August 27, 2017 Hi Phil 9. You are going to get various answers here but I have personally found cross wire option works better for some reason some how the wires do not sag when in operation Quote Link to comment Share on other sites More sharing options...
Phil 9 Posted August 27, 2017 Author Share Posted August 27, 2017 Well I set them up not crossed and hoped for the best. having said that they still maybe twisted together but it is hard to tell without being able to see them Quote Link to comment Share on other sites More sharing options...
Ultymate Posted August 27, 2017 Share Posted August 27, 2017 Which ever works best geometrically for the model is the way I go, they will not bind when crossed if you use plastic coated trace wire from your local fishing tackle shop Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted August 27, 2017 Share Posted August 27, 2017 The most important thing with closed loop is this. The holes MUST line up in a straight line with pivot point. or hinge line. This applies to the servo output (I don't use the servo output) or the idler bellcrank and the control horns. Quote Link to comment Share on other sites More sharing options...
Jimbo565 Posted August 27, 2017 Share Posted August 27, 2017 Did this one a while ago and as Ultymate says no binding on plastic coated wires. Quote Link to comment Share on other sites More sharing options...

The holes don't have to be in a straight line, see drawings below (the 2x gearing is just an arbitary example) - a) Is OK but lines are under tension even when the model isn't in use causing unecessary strain on the hinges etc. b) and c) If the control surfaces are left off neutral when the model's not in use there's no strain on the wires or hinges etc as the non "pull" line loosens when the servo is off neutral. d) & c) The non "pull" wire will tighten in use Quote Link to comment Share on other sites More sharing options...

john stones 1 - Moderator Posted August 27, 2017 Share Posted August 27, 2017 Yep fishing line is best stuff, if it bugs you that they may rub, use ball links n put a washer under one to raise slightly. Quote Link to comment Share on other sites More sharing options...
Phil 9 Posted August 27, 2017 Author Share Posted August 27, 2017 I think I have it working ok now. More from trial and error rather than knowing what I am doing. It seems to work better with a cross over on the. Acro wot artf as there was some interference at the openings trying it straight through.

Dove from above Posted October 13, 2019 Share Posted October 13, 2019 I asked a question and was pointed to this great post. I have seen the picture where the control wire/cable is run straight through the servo horn eye. Is this ok? my loop kit came with wire,i was going to use some sort of connector fro wire to horn conection. its only a 36" funfly self build.

Bob Cotsford Posted October 13, 2019 Share Posted October 13, 2019 I've done that in the past but these days I prefer to use a short wire link maybe 30mm long with a Z bend on one end for the servo connection and a simple loop the other end for the closed loop cable to connect to. It just makes it easier should you need to swap the servo out. Quote Link to comment Share on other sites More sharing options...
