Let's Make Robots!

Cheap Servvos

Can anyone recommend a website where a servo is inexpensive?

Tupperware

Can anyone recommend where I can get Tupperware containers online? See, I'm working on a couple robot projects, and I was hoping to use a simple tupperware container as the robot chasis.

Flying bots

I'm working on making my own Robot controlled helicopter. Is there anyway to calcute the wing length of the blade in order to lift the helicopter?

Robot Website Question

I'm currently thinking about making a robot community portal website(sort of similar to newgrounds) after I obtain money to build my second robot. I was thinking about offering free swag from my cafepress store as prizes for monthly contests held on the site. Would robot enthusists really want free t-shirts,buttons,stickers,etc as prizes, or would they want hardcore robot parts? I'm sorry if this seems like spam, but I wanted to ask a community who has expertise in this field.
