thats the best thing thats been said all night there well done ashley
voice of reason
a must for every marshall no more burt fingers ether plugged or soldered


quick question for the other people that solder cells in, what was the reason you started to solder in ur cells, what was the changing point and why, ill give mine later i dont wont to influence the answers

Nice idea Ash, but I'd have to say that's equally dangerous. Just imagine slipping over while marshalling with those in your pocket. It wouldn't take to many falls to end up with something stuck in your leg.


Connectors or No Connectors, were talking very very small differences. Everyone's right, once it starts to smoke it's knackered. But one difference, if you see the smoke and manage to unplug before it gets to the point of flames, then the manufacturer is probably more likely to honour the warranty claim.

If you send back a molten chuck of chard plastic, they're likely to think "user error" first rather than product fault. It's not like they can identify the fault if there was one.

ah, but Phil, they could use the Northy theory, and examine the magic smoke to define the problem :) :) ;) :p

None of them are very pointy but i didnt think of it like that. But my keys are proberly sharper than any of the things i carry in my pocket. And my wallet acts as a good padding with all that cash in. NOT.:D

Sorry couldnt help but but in here,

First most cars have a fused link in the battery lead, directly onto the battery the idea of this is if you have a major short that it will burn out causing loss of the circuit hence loss of resitance hence loss of heat.

and the autolec switch fitted to all racing cars does the same its fitted in the main battery lead and once switched off the circuit is dead.

That doesnt mean that the wiring /component wont be damaged beyond repair but it does mean that as soon as the load exceeds the fuse rating the circuit will die.

My answer is carry a set of side cutters, believe me it cuts the power quick and on the spot ! the only thing i will say is if you do spare a thought for the guy whos car it is and cut close to the batt connections.

After all a soldered joint is far more efficient than a plug, but a plug is more convenient to the club racer (and certainly my thumbs...lol).

So each to there own weither you want convenience or effiency its up to you

That mho for what its worth.

My opinion, for what it's worth (which is next to nothing :):confused::)), is that this whole soldering the connections thing is superstition.

The resistance of a good connector is less than the cable that it replaces so the only way that it can reduce the performance is if it means you have to put extra cable in. I think if you're careful then it should be just as good. I bet if you did a controlled, scientific test then it'd show that there was no measurable difference.

As for big cars. Well, it's true that you need a spanner to take off the battery leads. But big cars have fuses! That's why your car doesn't catch fire when you short out the radio ;).

Just my two penneth ...

But i dont carry them for that reason i carry them for outting ball studs back on and pulling stuck motor brushes.

I'd put money on you being right ! So much of this hobby is full of this kind of 'speed secret rubbish' You'll be telling me I need to glue my tyres on next !

My point was simply the saftey of the marshall. A car that CANNOT EASILY be turned off shouldn't be allowed to race in my opinion, its dangerous to the marshalls and all in the immediate vacinity.

Carl, racing before I was born ! Well, your holding up well old lad, I didn't realise you were so ancient ! :) :). My point is simply that I have being racing for a good couple of decades and then some, and i've had to Shut off my fair share of cars going out of control, thankfully they have never had the cells soldered in.

thanks for the complement Andy, i don't often get told i look younger than i really am,lol i understand what your saying and have been there many a time
we have also lost numerous rounds and finals and even a national final because of dodgy connections, and for us that race week in week out it was to much a risk we have been soldering cells for the past 2 years and never had one disconnection, or for that matter one speedo blow up or fire,
its all down to good maintenance,and personnel choice,
and I'm sure Mick cragg and bradders and numerous others will aggree,
but if we all did the same it would be a boring old world would'nt it

so in comparason, how many servos cause a speedo to fry

try shorting out your big red wire to your starter motor, NOT all cars have fuses where they could hence why the fire brigade when on scene will pop a bonnet and cut the battery wires.

no one seems to have noted that when the smoke is release and as the car in this topic the speedo was still glowing orange, yes the speedo was goosed but how long could the cells take a dead short before poping, (see the rcracechat threasd on exploding 4200's.) glen could have been taking the car out side and have a cell go up in his face. now if im marshalling and see smoke ill look, if i can not unplug as its soldered in, then car goes down and i walk away, remember you marshal at your own risk and take steps to prevent injury to your self.

Please explain Carl how lowering the resistence in the battery connection, and therefore increasing the current the speedo can draw, can make things run cooler?!

If you have problems with plugs falling out you're doing something wrong, I've never, ever had a battery disconnect. It's not like I change them every 2 minutes either, I think the connectors on the speedo in my b4 have been on the speedo for at least 3 years ;)

That statment is quite correct actualy, a servo can blow a speedo, by having an incorrectly adjusted servo, under certain conditions, can spike the BEC circuit of the ESC, this fails, then the ESC goes open circuit and blows the FETS.

re: connectors, a well maintained gold plated corally/deans is just as good as a solder joint, unless you suck the solder off each time, and solder adding fresh solder each time, then you might have an advantage, of maybe half to a quarter of the on-power resistance of a decent new FET....

A:rolleyes:

P.S. I pissed my self laughing at that but i dont know whats so funny about it:o

Ashley, you realy are up for most 'random' posts this month aren't you...

Nope i cant compete with the king of random northy:(

A;)

yeah, but Northy's are funny.....

Exsactly

as usual Richard Ur off down the wrong line again lol
so what your saying is a loose connector arcing out doesn't produce neat HMM
and your saying that corrallys never loose there spring, god how many times have i had to use a screwdriver to stretch the springs on them,
well i wonder why the likes of the big guns do this then Richard
do you think Mick, bradders, etc do it because its fun
i doubt that, and if connectors are good enough for you why the hell should you change i know i wouldn't,
but just remember the first time i see your car stop and find a connector has caused it, ill take the piss out of you all day,and as you know these thing often come back and bite us all in the arse

what i was saying is matthew lost a big race because a connector fell of it will never happen again,

there is a term for that "PPP" ;)

Neil used to use corallys, I have photo evidence! lol. At that level, i can understand it. For me it makes no sense what so ever. If you wire your corallys up properly they wont fall out anyway - a long length of wire that is free to wave about and a forward facing corally can pull out, just wire it different and if the connector is old, replace it.

I used to use DEANS, some of them got loose - not loose enough to come apart but loose enough to desolder because of the bad connection. but they were 3/4 years old!

I will admit, on batteries, I use Corally, and as long as the tube is in good nick, and your wiring is tidy and neat, then the only way you will get a disconnect is if your cells shift, and then that could be a good thing anyways.

Mark, on the first page you said Adam's car got hit before it went up in smoke, not quite true if you ask him. He told me the car just died and he tried to steer it off the track.

I think Adam solders his cells in as normally he's racing in the top 10 at nationals, so you try to minimise the risk of anything stopping your race... hence, soldering the cells in. Most top 12th drivers do it.

yeah I'm sure must people at one time or another have used em and loved or hated them,it's down to personnel choice,ares is to solder.
I'm not saying its for everyone,
and Richard look here what jimmy has just wrote
(I used to use DEANS, some of them got loose - not loose enough to come apart but loose enough to desolder )
do you think it desolderd because of the lower Resistance lol
no it desoldered because of a heat build up caused buy shorting my point exactly,yippee cheers jimmy not just us it happened to then

Resistance = Heat!

If your having to stretch the spring then it was knackered in the first place and needed replacing.
If a knackered connector is changed then it might not fall out at the most inappropriate time....;)

Carl Carl Carl, read what I wrote again ;)

I never said a higher resistance connector generates no heat, I said I don't understand how soldering the cells directly to the speedo can reduce the temperature of the speedo, motor and batteries as you claimed. If anything it's going to be the other way round, removing resistance between the cells and the speedo will let the speedo draw more current and actually make everything get hotter.
If your corallys are getting hot enough to desolder you need to look into your car prep, thats user error not the fault of the connector :p

It's personal preference as to weather you solder or pulg your cells in, but you can't use "but Mr xxxx does it" as the basis for your discussion as there are no facts to back it up. Please explain how a lower resistance connection between the cells and the speedo reduces motor/speedo temperature.

Besides Neil runs a B4 not a CR, so by your logic your Matt should be running one too :D

I think I'll start glueing my thumbs to the tranny sticks, just in case they should come off mid-race. :cool:

Right just to be pedantic using a constant current load a corally connector (3 years old from my B4 ;) ) has the same voltage drop and therefore resistance, as roughly 5cm of typical power wire. That includes the resistance of the copper bar and the solder joint connecting the corally tube to the cell.

:::edit::: Just for more comedy effect, it should work out to be about 0.012v drop at 30 amps.

How long are the wire runs in that XX4 Carl?! :)

I used to solder my batteries in but gone back to corallys because just before a race I put a set of cells in which where not charged and could not change quick enough to make the race( having to desolder the cells). This is my personal preferance. (Any driver can make a mistake like that and dont say they cant.)

richard richard richard
god im bored already,
read what i wrote, i never said soldering directly reduced the heat in the car, i said since i stopped useing corllays and deans plugs (well i didnt say ether plug buy name) but since i stopped useing them (because they shorted out causing heat, the heat in the car is less,
which if you had botherd to read is'nt the main reason i stopped using plugs (quote)
we lost a major final run for matty because connector come of )
and i would rather watch my car burn instaed of losing a run dew to crap connectors
and what the f++k is neils b4 owt to do we me not running one
buy my logic wtf

just to be pedantic SPOT ON
COMEDY EFFECT
YOU WOULDN'T KNOW HOW
so come on Richard prove to me why almost all the big boys are wrong
and ill go back to corrallys
just for comedy affect
i obviously after 25 years of racing have no idea
why do they do it please tell me
i don't know
but do you

comedy.

quality


ooops sorry wrong thread wrong site
lol
it getting my post count up i hope jimmy hasnt cottoned on
oops he will now

Can I participate????

Rich,
I have recently had this. The cause being I was using brand #1 male corally type plugs and brand #2 corally type tubes. Although they felt secure, I had the tubes desolder from my cells as the resistance was so HIGH.

I went to soldering cells for most of the winter.

Now, I have gone to the LRP silver connectors, and they work great. A real nice fit and look cool too. And since they are the only silver version, I won't be mixing/matching my connectors ever again.



Carl,
For the tiny advantage in reduced resistance in direct soldering, it is far outweighed in the huge disadvantage in that its a right freckin pain in the arse!!! Then when an ESC goes up in smoke... well... you'll find wire cutters aren't easy to find trackside. :D

Anyway I hope the geezer gets his speedo sorted fixed for free very expensive things these speedos. And I dont mean the swimming attire.:)

Wow, this thread is "heating up". I hope it doesn't turn into a "flame" war. Heating up, flame, get it? I'm here all week.

Sorry. Worst joke ever.;)

hehe this is funny :)

Not to be awkward Carl but you have an amazing habit of quoting people out of context to your own advantage.

Reads a bit differently with the last bit added back on ;)
(That would be arcing btw)


I never said it was wrong to solder cells in, I origonally asked how it could keep the electrics cooler. I don't know why people bother to do it for the miniscule voltage increase the speedo sees, thats my point. Prove to us why you apparently must solder cells in.
It's certainly not for an increase in power as lots of people these days claim to be able to make their car too fast for the track, other than the connector falling out due to poor car prep why do people do it?

Now now play nice :)

o i agree with you Chris
some times soldering is a right pain in the ass and yes we've run back to the pit table because i forgot to solder em up
I didn't know there were 2 different kinds of corrallys,
please explain may be there in was our problem
but as i said i only really changed over because we had a connector fall of mid stream a good race
whats these LRP ones like i come see at batley if thats OK??

would you be able to tell me where you got them (and dont say lrp lol) i mean what shops stock them in the uk
