Hey guys my father and I have been flying RC for around 10 years now off and on and my dad has started to get interested in electrics. We have always flown glow and don't really know anything about electric. The question is, how do you know what ECU to use with which motors and which batteries etc? Is there a good place where there is/are article(s) on getting started in electrics that explains the basics from the beginning? Another question, when a motor says it's a 400 or 600 etc. that means 400/600 what? Thanks for the help guys!

It's funny, dad's going micro and I'm concerned with CCs...
