Hi
Try taking two pieces of outer ny-rod tubing about 3-5" inches long ,take some string and tie the tubes into an " X " ...
put your pull -pull cables thru ( crossed Respecfuly ) ( can not spell _d)
The tubes will fall into place where the cables will cross....[sm=thumbup.gif] ....
Check out the books From Mr. Don's [link=http://www.donshobbyshop.com]Don's Hobby Shop , Salina, KS[/link] ..
His Book on "Gas Engines- Giant Planes Contains a Easy setup for "pull-pull "......
Hope helps....
Here some pics.
