I've only just started it, and I'm already stuck. I can't, for the life of me, get the larger pins on the analogue sticks desoldered. I'm using a standard 17W soldering iron. Here's a picture:

As you can see, I've tried melting the solder to no avail, and the PCB board is starting to burn. I've also tried dumping extra solder on and melting that, but that doesn't work either. Help anyone?
