I got a couple HobbyStar 5S - 1600mah 120C packs that I need to change the plugs to Deans to match my ESC. I tried soldering yesterday and found the 10 gauge to need a lot more heat than the smaller 12 gauge on the 4S 25C packs I had been. I got these packs cause they weight a little less than the standard 1800 mah pack normally used for this size ship (Ringmaster) and it fits in the nose tank area which also helps the balance.

I got one wire on after trying three different soldering irons - 40 Weller Iron, Weller 140W Gun, 150W iron. The 150W iron worked the best but because the tip is rather large makes it more difficult to get a good contact with the plug lead. Has anyone soldered this weight lead and what solder, iron, method did you use?

Thanks,   DennisT

Did some internet search and found out I was a little lazy on keeping the gun tip clean. Once I got it cleaned off and tinned SUCCESS!!

MM, that tin both pieces tip worked well, thanks.

Glad you got it. On my gun, sometimes the nuts that hold the tip get loose and that robs heat too.

The key to soldering anything is to make sure all the bits are clean.  Go ahead -- be obsessive about it.  Soldering is one of those areas (like painting) where obsessive cleanliness really does help.
