60W shld be fine! I do that with a 20/200W without needing to push that extra button.

What helps will be melting some solder on the thicker part of the tip and bring it to the bullet.

Perhap you shld drop off solder on the bullet and wire side first. As much as needed but not a blob of ball formed.

Then with the hot solder clinging onto the gun now, make use of the hot solder to transfer the heat to the bullet (becoz the bullet has bigger volume to absorb the heat faster), rather than relying on the heat from the tip to heat up the bullet to melt the solder.

The melting solder carries almost the same temp as the tip but transfer the heat to the bullet more effectively then jus the tip alone as it is in liquid state. Try again..

One other thing about soldering is that the tip of the iron has to be good. When the iron is hot and you melt some solder on the tip, the solder should flow and "wet" the tip. If the solder just forms a blob and doesn't flow out, you may as well forget it- you'll just be frustrated trying to solder with a tip like that.

Buy a new tip, learn how to tin and clean it, and it'll last a long time and give you nice results.

That's the point, it was an 18w that was claiming to be "equivalent to" a 60w, if I had a 60w the thing would be wired up by now. I hate marketing. The only connecter that I could not do was the huge 8awg on the battery, it just wicked the heat too quickly to get the job done.

This conversation made me curious, so I went out to look at the iron I use for my heavy soldering- wiring harnesses, soldering Dean's connectors to 12 AWG wire and so forth. I was sure that it was a 35 watt, but it turned out to be a 25 watt iron. It does have a large chisel type tip.This iron does those heavy tasks no problem.

If you're going to be doing soldering, you really need to bite the bullet and get a good iron like a Weller and some decent tips that are sized for the job you're doing.

This is the soldering Iron I use:
http://www.ebay.com/itm/60W-Solderin...item3a73bbd784

Came to me in a couple days, and has been working great! It heats up in a couple minutes, and makes soldering a very quick job! You have to be quick, or else you're going to mess up whatever your soldering (unless its heavy gauge).

The XT60 connectors I am usually very quick with. I tin the wire ends, and the connector, then let them cool. Then i'll hit them quick with the soldering iron to combine the two.

I need a 20-25w or something adjustable because you cannot solder to PCB boards with this thing.

This is the next Soldering station I want to buy: http://www.hobbyking.com/hobbyking/s...arehouse_.html
Im just upset I didn't buy one when they were in stock. I saw this exact same model, under a different brand name, for $119 at my local Fry's Electronics. Too bad too, cause Fry's will match Internet Prices, however I doubt they'll honor the price of another Brand.

I got it soldered this afternoon, even got one full pack through it before I did a tumble and bent one of my alu arms. Electronics are fine and I'm going to bang it out tonight and see if its salvageable. In the market for a frame that takes 11 props. As much as scratchbuilding can be fun, flying is more fun. :-)

Yep, frame is a loss, time to rebuild. Electronics are fine, but two of the motor mounts were loose and needed to be tightened. Not going to stay up all night, I have a marathon to run in the morning.

Good luck on the Marathon brontide. What time are you going for?

I have been working on a few more frames this weekend...

The bigger one has 10" props with Tiger AT2216 1250kv motors and will run off a pair of 3s batteries. The small one in progress is an idea for running 8" props on 4s with the same motors. I am trying to build the smallest quad that can carry all the stereo camera and FPV gear. Although small it will still weigh about 1.8kg

cheers....phil

Ditch the CD casing use a plastic RC Car body it would look perfect for a covering.

3:32:22, not as fast as I had hoped, but still a personal record.

Nice. I am going to make another attempt at breaking 3:00 at LA in March, It is proving elusive :-)

About the CD case...I love the geeky home made look of that round case. But do you have some examples of quads with car bodies?
