Solder or Bullet connectors, Advice?

[freemundo]

Why do I keep buying crap from ebay! It's more stress that the money saved.

I have recently got a Novak GTB esc and Novak 13.5 turn brushless motor.

The problem is the ABC motor wires are to short and need to be extended.

I have tried to unsolder the wires from the PCB and replace but the soolder seems to have higher melting point than my 60 watt iron can produce.

My only other options are.

Slodering the wires together or use bullet connecters?

Any advice?
