Need help building my nephew a Beyblade!

First let me apologize if this is in the wrong location.

I'd like to build my youngest nephew a Beyblade for Christmas so he can compete against his older brother. He's 5 and can't get it to spin quite as fast as his 9 year old brother and pretty much loses every time.

Is there a combination I can build that could at least help him to win sometimes? Not sure if there's different stadiums but they usually play in a red, plastic stadium.

Any help is greatly appreciated.
Thanks for the apologies in advance, as yes, it's the wrong section. Smile Please post this question in "Build me a combo".
