Ifly it using my U/Tronics Control 4 channel system. Throttle, Wing Warp, and Rudders. Channel 4 is unused. The Wing Warp allows me to do a Wing Wave as an option and level the wings in flight. The Rudder allows me to adjust the line tension. See Picture of my handle. I have also posted a copy of a drawing I did explaining how to hook up my system.

As for the lines I am using nylon jacketed fishing line but Ican recommend using standard flying lines coated with two coats ofwater based Polyurethane.

As for the wires breaking at the connection to the flying lines. I place a one inch piece of 1/4 In. shrink sleeving on the line before making up the end. I use bright brass of silver colored crimp sleeves to make up my flying lines. After crimping the sleeve I strip and tin at least 1/4 inch of the insulated wire that will go to my connector. With the insulated wire laying back along the flying line solder it to the crimp sleeve. Starting 1/4 inch on the insulatedwire fold the insulated wire over and cover the solder jointand crimp sleeve with the 1/4 In. Shrink sleeving and shrink it. This supports and helps protect the solder connection. Except for the original setup of my Single Channel unit all of the controls systemsneed tomaintain polarity of the lines. I personally use 3/32 (Miniature) ear phone jacks and plugs.
