Brushless - the definitive guide

[Hog]

Right - I'm confused.

I'm hoping to make the switch next year to brushless, but I'm looking to probably mix and match ESC and motors. So I don't go making expensive mistakes, can someone try and write an "idiots guide" so far as sensored / sensorless / bonded / sintered / etc, 'cos I just don't understand, especially the sensored / sensorless bit.

I'm going to need to run both modified and stock, and over the winter months I'm hoping to go LiPo as well.

Please don't turn this into a "get this one mate, it's the dogs, and better than that one" type thread - I'd like to make my own judgement, but I'd like to make the decision armed with as much info as possible about what ESC's are compatable with what motors.

Thanks in advance.
