Help with Beyblade?

Hi there, I'm new here.

I have a 4 year old son, and he's in love with Beyblade. I want to build him a good top, but, I don't know anything.

If possible, I would like some insights on how they work, what the terminologies are, what does each part do so that I can have a general understanding of it and be able to build him one. Any suggestions on what good tops are would be VERY welcome!!!

Thanks!!!!
Go here. List all the parts you have and someone will help you out.
Also, Beywiki, which is the WBO's own Beyblade encyclopedia is very helpful in obtaining information there. It's suggested to users that they read it first before asking questions.

Also on Beywiki is the Beyblade Parts List. Make sure you scroll towards the bottom of the page to view the Metal Fight Beyblade/Beyblade: Metal Fusion Parts lineup.
If you have any further questions, please post them here and do not make a new thread.

Good luck on your purchases!
