What is the best brushless motor for powering a 300x30x6mm blade on a kilobot?
It will be on 11.1v.

Inertia XL & NST are to my mind some of the best spinners around and neither go for the brushless motor.
I would stick with something more reliable and easier to control. Some 150w motors would be fine.

150W motors might be a bit overkill on a kilobot

I think with brushless motors for kilobots/beetleweights/whatever-you-want-to-call-thems, it'll very much be a case of trial and error. There are a range of motors and controllers on GiantCod (as well as the internet in general) so perhaps just pick one that seems reasonable-ish and see how you get on.
A 300mm long spinning bar though? That's huuuuge! :shock:

I doubt most people will have the space or weight available for a 150w brushed motor in a Kilobot though.

I'm using a 250w 1400Kv brushless in mine, at 50g and Â£8 a pop you can't complain.

On the other hand though we're using some fat brushed drill motors to power our weapon in Bitza 2.

To tag on from what Jamie said, one of the main things that appeals to me about the weight class is that it's a level playing field for everyone, as its all new territory. No one knows what does and doesn't work! Also the spinning bar o my Kilobot is 320mm so I'll let you know how I get on!
