mamba max pro problem

[himalaya]

Cool info patrick, it feels so great a manufacturer shares the "know how" technical detail with customer. I don't remember anyone else did that better than you.

MMP
castle 2200kv
hyperion 4s 5000 g3
15t pinion
50 spur i think what ever stock is
the motor never got up past 100 and the esc would come off at 115ish after 7min
hats off to castle you guys did a great job !

but the bullet connectors for the 2200motors are 6mm and the bullet connectors on the MMP is 4mm, so you just soldered 4mm bullet connectors on the 2200 motor cables?

other question:
4mm = up to 75amps and 6mm is up to 6mm amps.
What does that difference do to the relation ESC - motor?

[Unsullied_Spy]

The CC 6.5mm bullet plugs are rated to ~200 amps. It is like putting a bigger pipe in your house to let more water in. It's possible to flow extra water through your smaller pipe but it will strain the system more, the larger pipe (bigger plugs) allow for more flow. Connectors aren't a huge deal with trucks, 5.5mm plugs are typically plenty for the motors and Deans can handle the batteries fine. In higher draw applications like a boat you really need larger connectors, I've seen Deans connectors literally melt together in a boat.

Also, smaller connectors (or lower current rated ones) simply have higher contact resistance. Higher resistance creates a voltage drop at high current, which makes less voltage available at the motor and also heats up the connector (v drop * current = power dissipated).

i just use the 6.5 bullets on my pro

Well overkill doesn't hurt.

That does it. I'm putting 8MM plugs on my MMpro and run a neu motor in a dragster.

Lol the connectors are going to weigh more than the speed control. I think you should just use the Anderson powerpole connectors, you know they make them in multipole now.

Coolbeans, I'll use a set in my pan car. I have to eek out every millivolt for my servo.

but how do you guys change the connectors on the ESC itself than I wonder?
fit the connecdtors on the Pro are 4mm, won't any connector that is bigger fit?

All you need to do is heat the connector up with an iron, the solder will melt, and then you can remove the plug & replace it with a larger one. Not difficult to work out at all. Only thing you need to do is add a little extra solder into the new connector before inserting the wire, then after its cooled down add the heatshrink tubing- heres a video for the hard of learning:

You can stick 10mm bullets on 16guage wire if you so desire, it wont make the slightest bit of difference to how the esc or motor works- the reason why the MMpro uses 4mm bullets is because A) they're cheaper & B) larger bullets arent generally required given the size of motor and application the esc will be typically used in, I.E. a 1/10 stadium truck or 1/8 buggy. You've had all this explained to you atleast once or twice now, no need to keep asking about using bigger connectors, as at the end of the day its down to user descression; if you plan to use the esc in a setup that will pull a fair bit of current, then common sense dictates you should use larger bullets. Provided you dont do anything silly like use the MMPro in a 14lb MT with an XL motor and gear it to the moon, as CastleCreations have already stated what applications the esc is suited to I.E 1/10 STs and 1/8 buggies- the smaller cms36 motors use smaller plugs, so that makes life easier when connecting up the esc. If you want to use a larger motor like a ~1512 for example (ideal 1/8 buggy motor), then you will need to change the connectors to somethign more suitable.

[snellemin]

5mm or dual 3.5mm plugs is the biggest I would go with the MMpro. But nothing beats a direct solder connection. I just wish the MMpro motor wires were a bit longer.

yeah okay but that movie shows how to solder it to a motor cables, but what I meant was how to solder bigger 6mm connectors to the MMPro wich has originally 4mm connectors...

if the ESC MMPro has prelocated space for 4mm connectors, how can a bigger connector be soldered on that prelocated space when that space is to small...do you know what I mean? :)

[J57ltr]

Don't worry about changing the connectors unless you upgrade the wires as well. What is being said is that there is no point unless you upgrad the wires. It would be like installing a large 3" (76mm) high flow muffler on a stock 1.5" (38mm) exhaust system, there is no point.

I dont mean to be rude, but are you really trying to tell me that because the wires are coming off the esc and not the motor, that you cant work out how to change the connectors with EXACTLY THE SAME METHOD?!?

1. REMOVE 4MM PLUG
2. REPLACE WITH LARGER PLUG

It doesnt make single bit of difference where the wires are attached to.

Like I said before, and has been said to you by several other people (all with more patience than me evidently...), it doesnt matter what size the wire is, you can always use a bigger connector simply by removing the stock ones- you just have to use the same size male and female ones on the esc wires and motor wires so that they match up.

Or like other guys said, you dont even have to use connectors, just direct solder the wires together with a butt-joint or butt-joint connectors to make a more solid joint. IS NOT DIFFICULT TO FIGURE OUT, YOU ARE OVER THINKING THE 'PROBLEM'...


EDIT:



See the 3 wires coming from the esc that have the 4mm plugs on & that go to the motor? All you have to do is remove them, and solder on the larger plugs- I dont understand what you are talking about with regards to a lack of space? The plugs are not on the esc itself, they are on the ends of wires- there is no lack of space available to put on larger connectors- you just need a little extra solder in the connector before inserting the wire to take up any slack & ensure a solid joint; exactly as I said last time.
