do I really need 5.5mm connectors

[sansouci01]

I'm sure I will get plenty of opinions on this subject. I'm new to rc boats and purchased an impulse 31. I'm running it all stock with 2-2s 4000mah battery packs. I have read tons of posts saying that you should change out those deans connectors for 5.5mm bullet connectors because of the heat build up in the wires. All the posts state that deans can only handle 60 amps and will over heat. I have been watching my temps when running my boat and I really have no problems with the temps. The hottest wires are the motor wires and they only get up to maybe 110 degrees. The deans connectors get to 105 to 108 degrees. I'm really not pushing my boat. Only 5 or 6 minute runs at 3/4 to full throttle. Should I go through all that trouble to change connectors if my temps are well within range of what most people say are safe.....

It isn't just the temperatures. Actually by the time you get the hatch untaped and the IR gun on the wire they have cooled off quite a bit. The Deans will cause extra resistance, which will reduce your speed and run time with no upside. Whether you change them or not is up to you.

5.5's are the standard now days. Buy yourself a nice packet of them and do it all. Ive tried a few brands and honestly the best are the ones right here at OSE. I have also bought a certain one from HK and I believe them to be the same as OSE's but you never know. They are compatible though, which not all are. Some are long, some are short. So buy enough to take care of business!

Thanks...It does take a little time to un-tape the hatch and get a temperature reading. I guess an hour worth of soldering is good insurance for keeping the temps down. Another question...I just purchased some 5000mah batteries. I presume I should get some longer run times with these batteries which I guess would heat up the connectors even more...

First time out with your new batteries don't run them until LVC, bring the boat back in about 2 min. and check temp. Also, part throttle is really hard on the ESC, especially on the capacitors. Longer run time is fun but if you keep an eye on the temp ( batt./ESC/Motor) they will thank you later.

I have a friend who recently purchased a IM-31 (V1), he told me has not had any issues with the Deans battery or 3.5mm motor connectors and plans to keep his boat stock. Having said that, I've read that Deans are only good for about 45-amps, if true, then yes, 5.5's would make a big difference.

I got my IM-31 bout a week ago, I'm replacing the stock speedo with a Seaking which come from the factory with 4mm bullets and users choice of power connectors. I've already replaced my 3.5mm motor bullets with 4mm to make it compatible with the Seaking ESC's.

For the power connectors I'm using Traxxas - I believe they can handle as much or close to as much current as 5.5mm bullets. Remember, they have several cars (4 dragsters + XO-1) with mega monster Castle motors that propel them to speeds of up to 100mph. If those power connectors are inferior, then how do those cars go so darn fast without a meltdown??

For me the power connector issue is more than following fads and / or doing what everybody else does, it's a matter of time & economics. I would have upgrade 28 batteries (many of which were converted to the Trax connectors from other types), 3 Traxxas trucks, a couple boats and a partridge in a pear treeee.

Traxxas states "The Traxxas High-Current connector flows current like a firehose with virtually zero voltage loss due to power-robbing resistance". Is that truth or advertising?? I'll let you be the judge.

Why? Because aerodynamic drag is ten times less than hydrodynamic drag.

[lenny]

Boats have more drag all the time than any other rc out there,
And pull a lot more amps than any other rc out there.
That is why the 5.5 are number one for most boats, Than 6.5 and 8 for really big setups.

Lenny, you and H2O have both made good points about boats having more drag / hydrodynamic drag, I hadn't taken that into consideration because I'm still fairly new to the boat thing. Most of my RC experience has been with RC trucks and as you both pointed they have a lot less drag.

Please consider that in my case I would either need batts that are dedicated to trucks and one's dedicated to boats or switch everything to 5.5's. As I already stated, switching everything to 5.5 is just not a practical solution for me and my needs.

If I was racing or running a Leopard 4074 / 4082 on 6S that would an entirely different story, but I'm a sport boater running a stock motor on 4S (2x 2S).

Both AQ & PB use 4mm ESC<->motor bullets on all they're good boats... MC, LO, UL-1, Revolt, SVR - BJ26, IM31-V2, MG29, etc, without any issues - something to be said for that.

Just found this in the swap shop... http://forums.offshoreelectrics.com/...e-ESC-AQUM7011 - check out the wiring - That's how my Seaking will look (with shorter batt wires) when I install it.

You have been warned. Dont cry on here when you smoke your electrics cause the deans plug melted and it shorted out.
I will never understand why people ask advise on forums then decide they know better and do what they want anyway....
I have deans plugs on my centurion cat, its a 3s boat with a 30A esc i consider that safe and have had no dramas as yet. If I had a 50A+ ESC in it I would go up to 5.5mm.
My genesis, rigger and both my rc cars with high amp turbo ESC setups and low turn motors run 5.5mm.

[sansouci01]

You're right Tristan. Already ordered some 5.5mm connectors and will changed everything over as soon as they come in. I just moved up to some 5000mah 50c batteries and they already come with the 5.5 connectors on them so this is a no brainer...Thanks for all the advice

[TristanJones]

Great choice mate! Happy boating!

I switched to Traxxas connectors on all my rigs a couple years ago. If you'll take the time read my posts as I wrote them, rather than as you interpreted them, you would find that I have stated (many times) that I sold the stock ProBoat 60A ESC (as well as the radio system) that came my boat in favor of a 120A Seaking ESC per the advice of the man who owns this forum, Steven Vaccaro.

His advice was part of a reply he sent me in response to a product inquiry e-mail I sent him regarding upgrade parts he sells for the Proboat IM-31. You would also find that I subsequently placed an order with OSE, I received my goodie bag yesterday.

Seaking ESC's do not come with power connector(s), it is up to the end user to install the power connector(s) of his/her choice, be it: Deans, Traxxas, 4mm, 5.5mm or .50-caliber (12.7mm) bullets. I further stated in post #6 above, that I replaced the stock 3.5mm motor bullets with 4.0mm motor bullets to make it compatible with the Seaking ESC's, the ability to handle more current was my real reason.

I will never understand why people ask advise on forums then decide they know better and do what they want anyway....
I will never understand why some forum members do not read peoples posts, rather they just "assume" someone said something they didn't, then post a hasty and sometimes nasty reply!! Do you know what happens when you "assume"?? You end up with hoof 'n' mouth disease

I did not ask anybody for advice, sansouci01 started this thread, in the first sentence he stated "I'm sure I will get plenty of opinions on this subject", and that he has. All I did was share my own personal experience's, as did Lenny, H20 and several other forum members, and none us "assumed" anything, nor did we post hastily worded or nasty replies.

Any more questions??

You assume I was talking to you, had you read my last post before this you would see I have communicated with OP.
