Default Help desoldering my ESC motor leads

I am doing something wrong!

I am trying to desolder the ESC motor leads from my Novac brushless motor so that I can shorten them, as they are far too long.

I am using a pretty powerful 50w soldering iron, but can seem to get enough heat into the joint.

The motor is still mounted into my Mi3, so I was wondering should I remove the motor to stop the heat escaping and if I should cut the leads off near the motor solder tabs so the heat can't escape up power leads and damage the ESC?

Any help would really be appreciated as the long leads make the car look really unfinished!

Thanks

Soldering is a bit of an art and I'm no expert. First, its far easier to resolder at the motor. But if you insist on soldering at the ESC, you want a large mass tip on the iron, put some solder on the tip first and it should melt the connection in a few seconds. A little flux will help too.

My fault for not being clear, I am trying to desolder at the motor end.

Cheers

Certain solders melt very slowly and you will need a lot of heat. Clean the tip and add some flux. Then put some solder braid in-between the tip and the solder you want to remove. This should remove the solder into the braid and the wire should be free. Then repeat.

Yes... Fresh solder on the tip of the iron will help get heat into the existing solder much quicker...

The slower the heat is applied to the existing solder, the easier it is for the heavy gauge wire to conduct it away...

For those works I think 80watt iron is better. Otherwise you will have to be a lot of time warming the cables.

That novak solder takes forever to start flowing. So put a lot on the tip before starting your solder.
