getting back into racing,

[boy_lard100]

Hey all, im after some guidance as have been out of racing a long time (15 years)

I used to race 1/10 buggies 4wd schumacher cat 2000ec until I couldnt get bits, etc,
Want to start up again but dont know whether to go 2wd or 4wd,

I liked my old schumacher and hotbodies buggies and wondering what would be good to start off with,

Also im used to racing with nich and brushed motors and seems this is far from the pace now,

I want to know if there is a back to basics instructions for lipo and brushless to read up on,

So any help would be appreciated, got about 300-350 to spend, what would you recommend?
