Need Advice Managing Castle 8mm Bulletts

[srislash]

Here's the comparison pic.

I'm not sure where the top one is from but the middle ones are Castle and bottom are the ones that I just got.
Just thought I'd throw this in the thread,hope it helps somehow.

the top one looks like an OSE unit.

There seems to be considerable differences in the mating surface area between various connectors. Given that more contact surface area yields better conductivity (and less heat, the criteria under consideration here), note the difference in length of the actual contact surface between these two connectors :

This (HK) connector is machined such that the end has a larger diameter than the middle of the "tangs" in a way that can prevent the full length of the tangs from contacting the full length of the female connector :

The Castle 8's appear to have a longer contact area than the FCR 8's pictured in the previous post :

Just some observations

Yeah, you wouldn't think these were both 8mm buttlets. The smaller ones are AM8MM from HobbyKing, and I don't know where I got the large ones - they look just like those SRISLASH recently bought. Where'd you get those? They are much better quality - thicker gauge metal and just easier to grip. Not to mention the increased 'heat sink' factor.

Edit: I read back, and see you got them from Fightercat. Much beter quality, IMO.

Guys... with all due respect... those TINY wires on the P-Ltd motors are going to look AWFULLY funny soldered into the middle of one of those 8mm contacts. Are you sure this sized contact is really necessary?? (rhetorical question... I already know the answer... )

SirBudman32,

I use this solder [ 62/36/2 from an electronics supply store ; $3.75 for a tube]. There's a few threads where the best solder to use is discussed, just search]. I like this stuff but others may/will differ.

After years of futzing around with just a soldering iron, I now use this setup to get a good solder joint. After liquifying the solder in the connector with the torch, I plunge the tinned wire end in, let solidify, then finish off with an iron. THEN smooth out the blobs with a dremel to eliminate pointy hot-spots.

In alot of applications I would have to agree Darin.I currently am trying 4mm connectors on my motor wires in my twin CF Shocker.No heat yet,but only a couple runs.Should only pull 100 amps in sport trim.If that.

Ha Ha, Could installing oversized connectors on Spec motor wires to keep the temps down tread dangerously close to reviving the "you know what" discussion ?

I can see 5.5's or up to 6.5's... and even there, the wires are swimming in solder in the middle of an overlarge contact. 8mm is HUGE. To each their own... I'm all for developing an optimum package, but I just want the majority to understand that it's doubtful that upgrading THIS far is going to be necessary for pretty much ANY P-Ltd applications. Nice to have the additional capacity, but likely pretty unnecessary.

Of course... I could be proven wrong... Maybe those 14 gauge wires on the motor can safely handle more amps that we think???

P-Ltd Offshore creates more heat than sprints. Needs more cooling. Let the games begin

Good call, Doug. My friends say that I have both feet firmly planted in the air

The extra cooling will definitely help, and likely be needed once you add the additional weight of those huge connectors and the additional cooling...

Surely you'll empathize with the chore of traveling 400 miles to race (with seven boats entered) that a little extra insurance helps. Offshore's rough on motors even with a decently balanced setup. I'm hoping to prove that a Cat can be ultra-competitive if it stays in the race for 4.5 minutes.
