What's best way to solder an ec3 connector on servo wires. I have a Y harness made out of servo wires powering a receiver and FB controller. I currently have deans on ends but wanna change out. Can the servo wire be soldered into bullets or should I use heavier gauge wire.

This is old but servo wires will eventually break in an EC3 function.They don't have enough gauge and stranding to fill the connection and prevent them from moving around. Go with a gauge that will fit.

There is no "best" way as fastrc1 mentioned....

But.....if you must....

My suggestion is to get some old 75ohm TV cable lying around....

And strip a length of the "bare" copper center wire....trim as necessary to fit in the EC3's "solder cup" along side the servo wire....Romex indoor 120VAC cable of a suitable diameter would work, too.

The point is that this cable will occupy space within the mismatched EC3 to servo wire junction....

Add shrink at the junction...and a fillet of JB Weld on top will provide some strain relief to the more fragile servo wires.

FWIW

As with all connectors, make sure the connection is soldered with the servo wire touching the side wall of the bullet.
