All this stuff has the capability to be dangerous, but none of it really is if you read the directions, ask questions here, and don't do anything stupid. It is good to check everything over many times.
I started out with a stock Rustler as my first rc, and slowly moved into powerful BL and lipo set ups. After the first two times running with lipo or charging them, etc, you get the hang of it and it really becomes quite easy to maintain all your lipo packs.
Just remember that if you are not sure on a set up of the charger or whatever it may be, just ask here, and we'll help you out.
