Information on motors and their application

[glx]

Hi, Used to racing RC Sail boats but new to RC cars and I got myself a B44 last year but didn't use get to use it much until now - wow what a car - great to drive.

But when it comes to the electrics not too familiar so is there a place where I could find information about motors like what the no of Turns mean in terms of speed/power or other... and what is best on durt or grass etc... and what is the link with the KV (don't know what that is either )

I know the difference btw BL and brushed and starting to get my head around ESC but the choice is quite vast...

So any help on T on Kv and applications for them would be most welcome...

Pretty sure not the first to ask and no I'm not ashamed of not knowing
