Do I solder these together?

[Matt King]

I have a new motor and esc, all my other parts of these have been plug ins. Do I solder these two together

No. You solder connectors onto the ESC wires, then plug them together.

A bullet connector?

Yup.

 

[Peeeenuuutt]

A bullet connector?

Correct. To my eye that looks like it should be a 4mm bullet.

add 4mm male bullets the bare wires then add heat shrink tubing to insulate

No!!!
you’ll bollox it up.
What ever size bullet the motor connectors are usually 3.5mm or 4mm
You want Female Bullet connectors .
a vice (preferably) and a decent soldering iron
And plenty of patience.
crimping is not reliable by its own, you want to cut back some of the female bullet from the narrower end .
place your heat shrink over the ESC wire first , Heat the female bullet to put solder inside where the wire goes, put the wire in & solder it, Assuming that held bring the heat shrink over the bullet to cover the wire you just soldered , heat it with a lighter it will wrap it self around the wire and bullet and you’ve done one ??
Repeat two more times .
