I have gotten these "no bulge/slotted design" connectors from two sources: HobbyKing and BidProduct. You have to look at the pictures carefully to see that they are the "no bulge/slotted design". <div><br></div><div>I really like BidProduct for acquiring large quantities of the smaller items, like connectors, extensions and hardware for my small hobby shop. Many items can be purchased with free shipping.<div><br></div><div>Ron</div><div><br><div><div>On Mar 30, 2011, at 4:09 AM, <a href="mailto:Houdini76@aol.com">Houdini76@aol.com</a> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><font id="role_document" face="Arial" color="#000000" size="2"> <div>Ron, what brand of connectors has the no bulge/slotted design?

I used to buy 3.5mm bullet connectors which had a "bulge" in the center of the male part. Recently, I noticed some 3.5mm bullet connectors which had no "bulge" in the male part. They push into the female part because there's a chamfer on the tip of the male part, which compresses the slotted male connector so it will fit into the female part. The big advantage of this design is that virtually all of the connector is mated with the other half, unlike the ones with a "bulge", which have significantly reduced contact area. Then I noticed that you can buy this same design in 4mm, 5mm and 6mm bullet connectors. My opinion - these are far superior.</div> <div><br></div> <div>Ron</div> <div><br> <div> <div>On Mar 29, 2011, at 6:30 PM, Verne Koester wrote:</div><br class="Apple-interchange-newline"> <blockquote type="cite"> <div class="WordSection1"><p class="MsoNormal"><span style="FONT-SIZE: 16pt; COLOR: #1f497d; FONT-FAMILY: 'Arial','sans-serif'">Jerry,<o:p></o:p></span></p><p class="MsoNormal"><span style="FONT-SIZE: 16pt; COLOR: #1f497d; FONT-FAMILY: 'Arial','sans-serif'">I started out with Deans Ultra’s. They worked fine but didn’t wear too well. The arc from connecting them together was really chewing them up. Then I switched to 5.5mm bullets. Those worked great and the arc did damage where it didn’t matter. The problem I discovered later was when I needed some more. Not all 5.5mm are created equal and I ran into some serious fit problems from one batch to the next. I noticed that most of the Europeans were using 4mm bullets. These are made a little different than the 5.5mm and have more “spring” in them so the tolerances don’t have to be so close. Like the 5.5mm bullets, the arc damage happens on the very tip which is not part of the actual electrical connection. I’ve been very happy with the 4mm bullets and will be starting my third season with them. BTW, I never noticed any power changes from the Deans to the 5.5’s to the 4’s. Hope this helps.<o:p></o:p></span></p><p class="MsoNormal"><span style="FONT-SIZE: 16pt; COLOR: #1f497d; FONT-FAMILY: 'Arial','sans-serif'"><o:p> </o:p></span></p><p class="MsoNormal"><span style="FONT-SIZE: 16pt; COLOR: #1f497d; FONT-FAMILY: 'Arial','sans-serif'">Verne Koester<o:p></o:p></span></p><p class="MsoNormal"><span style="FONT-SIZE: 16pt; COLOR: #1f497d; FONT-FAMILY: 'Arial','sans-serif'"><o:p> </o:p></span></p> <div> <div style="BORDER-RIGHT: medium none; PADDING-RIGHT: 0in; BORDER-TOP: #b5c4df 1pt solid; PADDING-LEFT: 0in; PADDING-BOTTOM: 0in; BORDER-LEFT: medium none; PADDING-TOP: 3pt; BORDER-BOTTOM: medium none"><p class="MsoNormal"><b><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Tahoma','sans-serif'">From:</span></b><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Tahoma','sans-serif'"> <a href="mailto:nsrca-discussion-bounces@lists.nsrca.org">nsrca-discussion-bounces@lists.nsrca.org</a> [<a title="mailto:nsrca-discussion-bounces@lists.nsrca.org" href="mailto:nsrca-discussion-bounces@lists.nsrca.org">mailto:nsrca-discussion-bounces@lists.nsrca.org</a>] <b>On Behalf Of </b>Jerry Stebbins<br><b>Sent:</b> Tuesday, March 29, 2011 5:29 PM<br><b>To:</b> Discussion -NSRCA<br><b>Subject:</b> [NSRCA-discussion] bullets<o:p></o:p></span></p></div></div><p class="MsoNormal"><o:p> </o:p></p> <div><p class="MsoNormal"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'">All E's. What size bullets have you settled on for your packs/ESC connections? Seems like something that would sorta get standardized after a lot of 70A usage. I have heard from 3.5 to 6.0. Would think it would work itself out to support the nominal max. I that most see. I am sure 3D needs all they can get but for AMA/FAI patterns seems like it otta round off pretty close for most using 5s packs.</span><o:p></o:p></p></div> <div><p class="MsoNormal"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'">Thanks ahead</span><o:p></o:p></p></div> <div><p class="MsoNormal"><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'">Jerry</span> <o:p></o:p></p></div></div> <div style="MARGIN: 0px">_______________________________________________</div> <div style="MARGIN: 0px">NSRCA-discussion mailing list</div> <div style="MARGIN: 0px"><a title="mailto:NSRCA-discussion@lists.nsrca.org" href="mailto:NSRCA-discussion@lists.nsrca.org">NSRCA-discussion@lists.nsrca.org</a></div> <div style="MARGIN: 0px"><a title="http://lists.nsrca.org/mailman/listinfo/nsrca-discussion" href="http://lists.nsrca.org/mailman/listinfo/nsrca-discussion">http://lists.nsrca.org/mailman/listinfo/nsrca-discussion</a></div></blockquote></div><br></div>=<br><br>_______________________________________________<br>NSRCA-discussion mailing list<br><a href="mailto:NSRCA-discussion@lists.nsrca.org">NSRCA-discussion@lists.nsrca.org</a><br>http://lists.nsrca.org/mailman/listinfo/nsrca-discussion</font></blockquote></div></font><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">_______________________________________________</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">NSRCA-discussion mailing list</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><a href="mailto:NSRCA-discussion@lists.nsrca.org">NSRCA-discussion@lists.nsrca.org</a></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><a href="http://lists.nsrca.org/mailman/listinfo/nsrca-discussion">http://lists.nsrca.org/mailman/listinfo/nsrca-discussion</a></div> </blockquote></div><br></div></div></body></html>
