Sticky idea

[Andy-j.smith6]

Hi guys

I am potentially returning to electric racing after over 15 years out of action. Things have moved on from the brushed motor and nicad days I was used to and I am a bit confused, particularly with a lot of the terminology for lipos, brushless motors and esc. I've done some searches on here and got some answers, but would be great to have it all in one place (apologies if it is already, but not found it yet).

Some example questions that might be good to have in a sticky so its easy to find.

Motors: What do the different numbers mean, e.g. 6.5T. Is lower more power, what would be a good starter motor, which would be good for a competent club driver. Guess it would also depend on the size of track and surface. But some top level advice would be good.

ESC: sensored vs sensorless? Anything else I need to know before buying.

Batteries: Nimh vs Lipo. In particular the Lipo terminology isn't the easiest to get to grips with, e.g. 6000mAh 7.4V 60C 2S

I am sure others would have different questions for the sticky, just an idea
