Dave, where you've been? Painting those mini bodies?

[DAVEC-NITRO-RS4]

Well, yesterday got the new shocks built and installed, the new motor broken-in and mounted. Picked up new rear tires, so I need to glue them up.

Still need skinny foams for the fronts.

Then the wiring chores begin. Who can recommend a good, reasonable priced soldering iron setup suitable for use with Dean's connectors?

Last "funny" thing...yesterday at HobbyTown I saw a brand new B3 kit that I could have bought for less than I have into this project....oh well.

If you go to a hardware store, look for a soldering pencil instead of an actual "gun". I am sure you can probably pick one up for cheap.

I have this one it works pretty good for the price.

[Ponch]

LH has one for $6 that can solder deans plugs on in less than 6 minutes of plugging it in. I don't know what the name is though, but I'll be picking on up soon.

[Tex]

try to get one that is 60W or better. They get hotter and makes the chore alot easier. It should be less than $10

[DAVEC-NITRO-RS4]

Thanks gentlemen. 60w pencil type it is. Radio Shack tonight!

[salsaking]

pencils are not usually that high wattage, I have mine from college that is 25w but its meant for smaller electronics. I use my portable butane weller most of the time cause I hate wires hanging around when I am working and my kids walk past. Its alot more money to get the butane one but I think its worth it. I just finished soldereing new wires and batts up for the MLST and it works flawlessly.

[DAVEC-NITRO-RS4]

yeah..45w was the highest I was finding at RS and Sears...should be fine.

[Ponch]

I have a butane one from RS, works great, but now the tip for it is like a little mound, not a point, oh and the part that holds the butane cracked so now I have to get a new one.

[Tex]

I have a portable Weller that I will give away, those suck ass IMO.

I bought my 60W iron at Al's for $7.99

[DAVEC-NITRO-RS4]

kewl

[dominick420]

test

[DAVEC-NITRO-RS4]

works fine!

[DAVEC-NITRO-RS4]

ok electric guys...last nite I got it all connected and ran this thing a little.

The wires between the battery and the ESC got warm-hot, but no other wires got even warm. The buggy did run.

What's your quess? What other info do you need? Who has a cheap (read "free") ESC they want to donate to see if the one I have is no good.

[UE-Maxx]

How about some pictures of it completed, Dave?

[DAVEC-NITRO-RS4]

It's just temped up. I didn't wanna hardwire too much in case something was DOA. I haven't painted a body for it yet, either. Picture today looks sorta like the first picture in the thread .

[UE-Maxx]

Oh ok.

[Toughtrax]

Dave what do you mean by hot, The wires from the battery to the esc do get a little warm from running it.

How about the esc was that hot or warm?

I used to race electric so if you need any help lmk and I'll try to help ya out

[DAVEC-NITRO-RS4]

I didn't run it for more than a minute or so, and the wires between the battery and the ESC were prolly above 140 degrees. Output from the ESC and the ESC itself were not that warm, much cooler really.

I'm running a 21x2 motor.

[Tex]

the wires from batt to esc will be the first things to warm up. Then the motor wires will be second along with the motor can. The ESC will get a bit warm also in most cases. Nothing besides the motor can should be HOT though.

Gearing is huge in electric running and keeping everything cool.

[Toughtrax]

Tex is right gearing in electric is key to keeping your motor and esc nice and cool, but if your wires are around 140 for just running it for a min or two then I would say that something is up. It shouldn't get that hot at all for that short amount of time.

What kind of batt are you useing and how many cells also what type of connectors are you useing on you battery and esc

What do the batteries feel like after you run it?

[DAVEC-NITRO-RS4]

7.2V 6cell stick Nicad
Tamiya connector from batt to ESC (haven't soldered the Dean's on yet)
Batt is cool when wire are warm
Heatsink on ESC is cool

I'm gonna test it again with the temp gun handy for accurate data.

I know no-load test will be less strain due to gearing, so I'm gonna do a wheels up test also.

[Traxxas_Junkee]

Does it get hot when it is just plugged in? Like if it just sits there with out moving does it get hot? Thats what happened my EVX went bad in my E-Maxx.
