UK Kilobots - 1.362kg (3 lbs) Combat Robots

[RogueTwoRobots]

Hang on, wait, what parts are you using?!
My wheels weigh 13g each and motors about 72g

my wheels weigh 100g together and the motors are about 70g

These work quite well, have a metal spur gear box and are cheap as chips. Speed is respectable on an 11.1V lipo but could do with a bit more oomph!! so a higher voltage would be good. Run time on a 300mAh lipo is half an hour or more.

Oh yeah! How come the 12a one is cheaper than the 10a and marginally more expensive than the 5a? It's lighter than the 10a too.

[RogueTwoRobots]

It seems a bit weird but the only thing I can think is that the 12A model is superseding the 10A model so perhaps it now costs less to make the controllers than it did a few years back when the 10A one first came into production, and they've found lighter ways of making them? Who knows

[PJ-27]

Now all they need to do is make a super cheap 5a one.....

[PJ-27]

Anyone know of a cheapy alternative for an ESC?

The current draw seems unlikely to top 5a but looks like I'll be paying the same amount (if not more since I got them 2nd hand) than I did for the ESC's in Bitza, which is far more powerful.

Cheers.

If you're running pretty small motors you could use servo boards. I personally use these http://banebots.com/pc/ELECTRONICS/BB-0309 which are pretty bulletproof, and here's an alternative one some beetles use http://www.fingertechrobotics.com/prodd ... -tinyESCv2

I definitly recommend the Banebots, I use the 3A ones in my ants and they're awesome.

Any issues getting them from America? Excessive postage, customs?
