I could make do with 12v. What ESCs do other featherweights use?
If I do use 12v would the bog standard cheap one do...

Before you criticize another person, first walk a mile in their shoes. Then, when you critisize them, you'll be a mile away and have their shoes.

BTW, this is how it's wired to my understanding...

No, it's more like this:bitternboy wrote:BTW, this is how it's wired to my understanding...

If you have an esc per motor (one for each wheel, one for weapon) they would be all wired like the bottom one.

Standard for drive are the Scorpion XL or XXL, Dimension Engineering Sabertooth 10A or 25A, or Electronizes.bitternboy wrote:I could make do with 12v. What ESCs do other featherweights use?

For weapon ESC's it varies. For the motor in the previous page the MicroViper should be fine.

That's good, BTW I could probably run the drive motors at 19.2v and the weapon at 12v like this...

P.S I can't really see any difference between you diagram and my diagram.

That only gives you more current, batteries need to be put in series to give more voltage.
To do it just wire the battereis up in series with a 0V wire from the side of the 12V battery, 12V wire from the middle of the two and a 19.2V wire from the side of the 7.2V battery
Although I still think that you will discharge the 12V battery faster than the 7.2V one due to it having more sources of current draw.
Edit: That should do it

Actually that doesn't give more current it gives more heat as the nicads catch fire. Connecting a 7.2v nicad across a 12v battery means the 12v will discharge into the 7.2 volt battery until both are at the same voltage or more likely the 7.2V is a smoking wreck. I would never recommend mixing different size or types of batteries it can be hazardous. As Jordan says you could connect them in series but you would have to seperate them for charging I think you would be better off using one or other of the batteries.

You could also set up a potential divider from a larger voltage battery and have similar wiring to the series batteries to give out the required voltages.
It involves a pair of resistors in series with you being able to clip in across them for different voltages without the mixing of batteries.
If you want a diagram then I can do one for you but they aren't too complicated
