  1. 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,...
  2. 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...
  3. 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.

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

    looks like choppers beat me to it =P

    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

    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.

    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...
