Servo extensions vs soldering new leads in...

Working on a new airplane tonight, hooking up the aileron extensions and tieing them together with fishing line so they don't come apart and I get to wondering: why not just cut the extension and splice in some wire? It would save the worry about the extension coming apart, and make it easier to run through the wing since the connection would not catch on the ribs while threading it through.



Thoughts?

TIA,

Rook

I never (well, almost never) use servo extensions. I do not use the extension wire, however, but purchase servo wire, and solder in an extension. Two reasons:

(1) Connectors fail.
(2) I'm cheap.

Only place I use a servo extension is from the receiver to the aileron servo connectors. If I need to extend a servo cable 12" or less, I use a better quality replacement servo lead and cut off the original plug, this way I only have a single splice in the wire, fairly cheap, but less work than splicing in wire with double the splices. Now if they'd just sell servo leads longer than 12", I hate to pay for an extension, then cut off the female plug, OK, I'm cheeeep

I always solder new wire directly on the servo PCB, and crimp on new contacts at the other end.
Here's a german how-to:

Ditto. Right now, I've been getting servo connectors and even wire from hobbycity.com. The connector set (both connectors needed for an extension) is $.40 and wire is about $.95/m. The connector set is actually better quality than the ones sold at my LHS for more than 10x the cost.

Alternately, you can purchase long extensions, cut them to fit, and solder them into the servo. I would not recommend soldering directly into the servos if you do not have some experience with very fine soldering. It is easy to damage the circuitry or bridge the connections if you are not extremely careful.

Cool, thanks for the link!
I need to check the small stuff from HC more often.

That's right. I'm glad I like soldering, otherwise, some parts of this hobby would be a nuisance for me.
