This video describes how to make an easily removable control rod out of piano wire for use in RC planes. A full article available at flitetest.com/articles/how-to-...
This makes it very easy to remove without unscrewing the servo horn! Thanks ! Been looking at this hobby on youtube for about 3 years and just now found this.
Wouldn't it be lighter to just use a short retaining piece on the end instead of making a double control rod? We called it "wrapping the wire with thread" in the 70s when building control line jobs. It was just common knowledge and we didn't think of it as a new invention even then. I believe this method has been used since the 16th century dawn of control rods.
The strange item is a "Whip Finishing Tool". It is used for making the finishing not when you tie flies for fly-fishing. You may just as well tie the not by hand, but once you have learnt to use a tool, you never look back.
Filing down the wire ends would probably be a good idea. The ends are not sharp enough to cut yourself on, but it is quite easy to cut the thread on the end of the wires by pulling on it while it rests on the edge. That is super annoying. Done it many times.
Naturally it is better and easier to use z-bends. This technique only makes sense when a double z-bend wire can not be installed. This is often the case for short pushrods in planes where the servo is buried in the wing.
Sure you could, but fly silk is much stronger and weighs much less. The weight might be less important, but the fact that lacquered fly silk will hold piano wired fixated forever is kind of important.
