I was wondering if you use sevo extentions if you have to wrap the wires together or not?

When I use them, I always cover the plug with a piece of heat shrink tubing so there is no chance of ever coming apart short of a fatal crash. Over kill perhaps, but it has never failed.

I prefer to make solder connections, but when I do use an extension, I tape, tie, or use some other method of keeping them from coming apart on their own

It is a good idea to tape or shrink wrap the connections together. It is cheap insurance.

If you are doing a lot of extensions, you will save a ton of cash by simply buying a spool of servo wire, cutting the servo lead in the middle, and splicing in the additional that you need. This way, you will have a near fail proof connection at a far lower price (most shops charge full retail price for servo extensions, since these small items are where they make the most margin).

Ernst servo clips. Lightweight and easy to deal with, almost foolproof. But splicing in servo wire is certainly the best option, if you can solder.

No, I mean do you have to braid the extentions together for radio interference issues?

If you are using three separate wires then yes, you should braid, twist or tie-wrap them together. If you are using three conductor ribbon cable (three wires bonded together by their insulation) then there is no need to twist or braid.

Some will tell you that ribbon cable should be twisted. In my opinion they are mistaken.

Be careful using extensions which never get opened/closed on a regular basis, especially if not gold plated. All of a sudden, you start to wonder why you are getting jittery servos etc. and, after unmateing and remateing the connectors, all starts working again. Many of the connectors used in RC will slowly get a coating or corrosion in the connectors that must be removed to get a good connection. The only safe way is to use soldered connections if the joint is in a place you can not occasionally unplug and plug again to remove the corrosion.
