how heavy?
what material?
flat or curved?

first off, don't constantly post after yourself. People aren't just waiting on the site to answer your questions. be patient.
To answer your questions, you want to make the rotor light, as it will spin faster and generate more voltage. You can use any material, some people like to use balsa wood. To answer your question about the flat or curved, i believe curved is better, but you really have to test for yourself. Try different techniques to see what works best. That's one of the main ideas for this event: test and find out. You can't be certain what's best until you try it and see for yourself.
