Wondering if its my iron or the hobbywing soldee thats at fault, really want to get rid of those colourful wires...
Do not just hold your iron on the terminals expecting it to melt (I believe it's silver based solder).
The trick is to apply more solder (sometimes quite a bit) .. bend the wires down at an angle, get the iron as hot as it can, hold on the terminal for 1-2 seconds, apply more solder (60/40 rosin core) to help get the existing solder to flow.
For reference - You should be able to get all the wires off in under a minute. If it takes you longer for any one terminal, give the ESC a little time to cool, you will notice it gets hot when applying heat directly to the terminals.
