Is it better to solder the extensions or plug them in.

The fewer connections you have, the fewer problems you have.

Instead of using extensions and "Y"s, I simply make my own servo wires to custom length. Yea, if you have to move the servo to another model, your wire might be too long or too short, but it's cheap insurance against a dirty or faulty connector losing the power or signal at JUST the wrong time.

Dr.1

And it always happens "JUST" at the wrong time! A little bulk servo wire and shrink wrap are awful handy

Although soldering is the absolute "purist" way to do it right, it becomes a pain when you need to change or work on a servo.
On my hi duty cycle servos, such as ailerons which get plugged in regularly, I use deans which work well and handle a bit more current than standard connector.

always beter to solder....but there comes a place where better for connections isn't a practable solution. you do have to change servos....hows your solder skills? would a short ruin a reciever?

Although a short does no good anywhere, it is easy enough to check for before plugging it in to anything important.

Good question.
I've never seen a shorted servo do anything to the RX. Or a stalled one either. But they work the battery over pretty bad.

Since moving up to crosscountry R/C gliders with 12'-14' wingspans, I've been a believer in soldering in the wires. It works so good and is so dependable, there's no other choice for me. And it's almost no expense other than time. And I do this stuff because I like to, so time is fun.

BTW, if you feel the need to change servos, what's wrong with retrofitting one with it's own extended wire? I guess I don't see the situation where it'd matter and you'd have to have a plug extension. It's as easy to extend the new servo's wire as it was the old one. And the old wire pulls a string when you remove it. Tie the string to the replacement's plug and pull the new wire right back through the wing.

Very positive answers. Soldering it will be.
Thanks Guys
