Alternative to Bullets

[Prozac]

What are some alternatives to 6.5 mm bullets. The first set I had ,I didn't get a good connection and destroyed when I was removing them. The second set, got solder dripped into the inside of the male end, so they wont flex and go into the female end.
I know I can direct solder, but it would be nice to have something I can unplug.

What else is there for connecting up a brushless motor with high current.

bullets are your best bet, are you sure u cant just solder them correctly?

Yes, that is precisely the problem. I didn't need re-affirmed of that, I asked what were some alternatives. I don't have issues soldering deans or traxxas plugs, but these bullets are evading me.

could be your soldering iron I had used a Weller 40 watt and that didnt get it done, I stepped up to the 100/140 model and it reaaly helped, I have since upgraded the tip to an all copper tip you can get at Radio Shack, and make sure the tip is clean, I used the old Deans solder that has the lead in it, you dont need any flux but they stopped making it due to the lead content. The 6.5 size were harder than smaller ones you need a lot more heat,

Have you tried using 5.5mm bullets? IMO they would be enough....I think the 4mm would be too small

One thing thats made a diff for me in working with the big bullets - once you've got it tinned, don't take the heat off of it. You've got to be ready to pick up the wire and shove it in there, so it takes having everything ready.

Not heating both the tinned conn and the tinned wire at the same time made a diff in the quality of what I get when its finished - they're better now.

If using a small iron, it takes a while to heat the connector up to the point where it will take solder. It's acting like a heat sink, and so is anything you are using to hold it (pliers, etc). I use a set of helping hands to hold the connector - the clips are metal so they won't melt, yet small enough to prevent too much heatsinking.

Even though a small iron works, you'll have an easier time with a higher power iron, especially if you are impatient.

I was at Radio Shack and bought those same helping hands I will say that was money well spent unless you have a very understanding GF who dosnt mind burning her fingers while you solder.....lol

FYI: Those same "helping hands" (minus the mag glass) are MUCH cheaper at PartsExpress.com. Yeah, you have to pay shipping, but still a good deal especially if you have to pick up a few other items.

I've switched back to hard-wiring my motor in, covering the joints with shrink wrap. I had some big gold bullets (5 or 6mm can't remember) and one went bad after a while causing heat buildup and it desoldered during a big race. Unless you have to switch motors often or really hate soldering I'd just skip the plugs. Cheaper that way too.

that is a great price...where were you a month ago......

lol, sorry, but you didn't ask. For electronic parts, I usually try allectronics.com first, but when I can't find it, partsExpress is the next place I go. Their electronics selection tends to be geared more for audio crossovers and such, but they do have a decent selection of other stuff considering.

I ll have to keep them in mind, I needed some large shrinkwrap for the 6.5 bullets for the MMM and I ended up buying an assortment pack at radio Shack when I already had all the other sizes...:-(
