5.5mm Contacts vs. 6.5mm Castle Creations Contacts? Anyone have a compare picture?

[properchopper]

Well, they are fairly equal contact wise though the Castle have more pressure and take a bit to disconnect. Castle are also a larger diameter so that gives more surface. The 5.5's are only longer by a couple mm's. Like I said I run 6.5's throughout and see no reason to change.

Not so. If you check the math in my earlier post, the 5.5's by virtue of their greater length have 172.80 square mm's contact area and the CC 6.5's have 153.160 square mm's contact area , therefore the 5.5's have 19.640 square mm 's more contact area than the 6.5's.

Manuel is correct in pointing out that the real factor in assessing current transference is the accuracy of the real-world mating surfaces of the connectors which is a product of the precision that occurs in machining and fabrication. Poor mating results in micro-arcing which translates to heat rather than current transference. Electrical energy OUT = Electrical energy IN minus energy lost to heat.

Hey Tony, is your math accounting for the cuts in the male connectors? I'm just busting your nads... Yep, contact area and good machining are tops.

Am I incorrect in saying it looked like the castle connector looked like it contacted in a longer area than the other one pictured above? Real world observation?

Are you referring to a custom adopted by my tribe centuries ago ?

[QUOTE=ray schrauwen;561107]Take a piece of any wire, be it 10G or 8G wire. If it is stranded and not tinned it has and X value of cross sectional conductance. As soon as you tin the end of that wire it all changes, the cross sectional area decreases to the external surface of the whole piece of wire.

As I understand it, in DC systems current flows through the whole cross section of wire, unlike the 400Hz systems I work on where it flows more on the surface of the conductor and less as you approach the center of the conductor. Hmmmm....I wonder if the pulsed DC out of the ESC behaves like an AC signal.

Might be a fun experiment to round up some different connectors and test them at work with the micro-ohmmeter, TDR, and Megger.
I have some Castle 5.5, HK 5.5, I'll see if my buddy has some of the Castle 6.5's....I wish my son needed a science fair project :)

I don't know if people are getting what I learned in grade 10 electronics class but, no matter. Your results would be great to see. I know Jans or Jeorg in Germany did similar tests waaay back on the 3.5mm connectors, Deans etc.. but, that was 10 years ago or more. Dunno if newer info is out by anyone else so GO FOR IT, please.

I was referring to the test that srislash did with a marker on both. May be my imagination but it looks as if the bigger ones contacted better. I dunno...maybe we are splitting hairs here because I did a back to back test with a buggy I have last week. I gps it with Ec5 connectors then put the castles on. It was the same exact mph to the tenth. I know not real scientific but still answered a question for me. I guess the buggy was supplied good enough with the ec5. My boat might be a different story.

OK, I got it now - I misunderstood your question; my bad. As far as contact area questions I guess there's some variation in how well the individual surfaces mate as well as the actual available surface area. Manuel's test (and Shawn's effort) shed some good light on this. Hmmmm.....

Sometimes I'm not good at explaining things lol

Yes it does. On a scope the DC pluses make a simulated AC sine wave...

I only use 5.5 mm plugs from Neumotors.com
I tryed all the others mentioned here and neu has the best bullets.

are they easier than 8 mm. to remove and can they handle serious current?

[MarkF]

Everything is easier than 8mm to remove. I just find the neus to have a nice fit without being loose feeling.

Now I gotta go looking Mark. hehe. I do find sometimes the 5.5's a bit loose. Not all, but some.
