    Gotcha. Actually this DMM has an internal switch that switches automatically between an ammeter and a volt meter. See the manual on page 25.

    Got a pic or a brand and model #?

    Here's one you can get for like $3 bucks on sale or $5 bucks normally

    You've probably got to change the position of the red lead on your multimeter. If you look on your multimeter, it probably has 3 red ports and 1 black port. If you take a pic of it and post it...
  4. Sticky: RE: Brushed Electric Motor Break-In Guide (Not Just For Heli's)

    One other note. Make sure you do this or you could get a fried multimeter. So the black lead plugs into the common, and the red lead is going to plug in to the Amp receptacle (vs volt or mA on most...

    You're welcome =)

    So what you have here is a parallel setup. You're looking for a series set up. To get it correct, when you look at your diagram, it should look like a circle.

    So lets...

    ahh, IC. I didn't see a way they could have an rx in there, but I guess if it's for dsm2 then there ya go.




    Yes on both accounts. This motor should start around .3A and work its way...
  7. Sticky: RE: Brushed Electric Motor Break-In Guide (Not Just For Heli's)

    ahh gotcha. So it comes with everything but the rx and tx? What an ARF really should be =P



    yeah, sounds about right.

    I do break-ins with my PSU. So what I do is run it on a...

    OK, this one then ;)

    It looks like the motor has some quick connectors on it from this picture

  10. Sticky: RE: Brushed Electric Motor Break-In Guide (Not Just For Heli's)

    The answer is it depends.

    Some of what it could depend on is how much money do you want to spend, is the motor likely to be used in a situation where it's better if it is disposable (like mud...
  11. Sticky: RE: Brushed Electric Motor Break-In Guide (Not Just For Heli's)

    Sure, no prob. A wet break in takes all of the oil out of the motor. Most people think that it's carbon dust coming off the commutator. Basically with the small motors that we are talking about,...
  12. Sticky: RE: Brushed Electric Motor Break-In Guide (Not Just For Heli's)

    Hey, no prob =) If it applies then it's not old to me.

    If you want to do a wet break in then alcohol would be a better choice than water because it evaporates more completely than water (so...
  13. Sticky: RE: Brushed Electric Motor Break-In Guide (Not Just For Heli's)

    10 min is pretty short to seat the brushes, although it's probably better than not doing one.

    So with no load these motors draw 27A each? That's quite a bit. My guess is that it probably draws...

    Sticky: RE: How to convert an ATX power supply to rc use

    if you mean while your computer is running? I'm sure you could, some of the risks would include, overloading the 12v rail with instant power off (most PSU's will do this when they get an undervolt...

    you can run the motors singly, or you can run them in parallel, or you can run them in series. For the motors I've done, I find that somewhere around 1/4th...

    RE: Li-Po for Newbs

    As far as how to treat it, yes it's a good idea to run a "form" charge on lipo's, 0.5C charge 2C discharge for 3 cycles, and allow the pack to cool down between cycles to something like 80F

    You...

    RE: Help on Charging two packs Lipo

    sure, no prob. Yeah things can get complicated quick. A good investment might be a couple of those cellpro chargers. They don't run too much, and they do a great job charging packs.

    I think you've kinda got it. What I would do is just use the one in the first picture. Depending on how it works, you wont need to use the deans connector if you have a balance charger setup. ...

    Sticky: RE: How to convert an ATX power supply to rc use

    sure thing. FSP group makes a good PSU for about 40 or 50 bucks that would be able to put out what the label says. If not, I'd just look for something that's more along the lines of 16 to 18A or...

    Sticky: RE: How to convert an ATX power supply to rc use

    it all depends on the conversion efficiency of your charger, but yes it will take considerable more power, about 33% more assuming a 100% efficient conversion factor. If it's a compaq PSU, it's...

    hey there, I got your PM, so here it goes.

    The formula for TDP is voltage squared over resistance, so it's 5.15^2 or 26.5/resistance. For series you add all the resistance together to put it on...
