Batch 2 V2 MMM

[Arct1k]

Did you disconnect from MMM - Those huge wires act as great heatsinks

[bdebde]

I think they use lead free solder, seems to take a bit more heat. I managed to get it by feeding a little more solder into the wire.

Yes, they were disconnected - I'll just snip off the ends and start from scratch. Does this mean that I should re-do the bullets (is there a compatibility issue with my solder and theirs that would cause a continuity issue?). BTW, speaking of soldering the bullets - I read about how people filled the cup with solder, then stuck the wire in. My bullets have 2 holes in them, so filling them was not really an option. However, I drilled my hole in the workbench a little deeper, so that the holes were covered and filled it that way.

No need to touch the bullets...

Or if you dont want to snip the ends try melting some other solder onto it, in my experience diluting it a little helps a lot.

i tried and failed with their solder. just ended up cutting my ends off and redoing it, as stated above

[JeffEmbracedDC]

In my current setup the bullet configuration causes the wires to push up on my body slightly. I think I'm going to re-solder the wires to the sides of the bullets at an angle instead of inside of them.

I'm still on a v2.0 with about 15 minutes on it.. I'm supposed to be racing tomorrow but I don't know if that's going to happen :(

the thicker the gauge of wire the more heat, flux and skill you need. A good 100+ watt soldering iron is a good investment.

I got mine done - clipped off the ends, and redid them with my solder. Took the MMM/10L up and down the street a couple times, and it operates as described.....just need to get some fresh packs in it to really test. I am REALLY unhappy with the lack of screw down holes. I hate the zip tie messy look.

Just got my v2 MMM yesterday!!!

Thanks Mike....

Should i direct solder mine, or do i need to get 6.5mm bullets? my MMM didnt come with any male bullets, the MMM HAS female 6.5mm bullets installed on the MMM, but no males???

It came with 3 motor wires 6" long, an 2 battery wires 6" long, stickers, a cd, a usb wire and chip to plug the MMM to the usb, but there isnt any bullet plugs...

My hobby shop has 4mm bullets , but no 6.5mm bullets, will the 4mm bullets work to conect the motor to the esc wires?

I read some post that said only 6.5mm or dirct solder is to be used/done on the MMM...

The wire's don't have male bullets on them on one end? Mine did, and the only thing I had to solder was my choice of ends to connect the motor (I used 6mm bullets for that). I did attempt to use 4mm, but the wire wouldn't fit into the socket on the bullet.

As did all of mine..

use double sided tape :P

[JeffEmbracedDC]

Personally I prefer cable ties combined with double sided tape over any screw mounts.

ah its good to see patrick and co are RoHS compliant. green manufacturing, the way of the future. yes that lead free solder is a royal pain to work with without the right tools/ solder iron. i just gave mine to one of the shop guys and hey presto...all soldered. TBH if i was to do it, i would have used the leaded solder, i am very impatient.
