How does stacking fans even do anything? You still get the same cfm going through each fan, so it wouldn't seem like you would get a higher total air flow. If you wanted overkill you should have gone for these 120's http://www.newegg.com/Product/Product.aspx?Item=N82E16835706015 with 252 cfm.

This is somewhat unrelated to the topic, but does anyone know where I can purchase about 6 or 7 servos for cheap? I plan on working on a little project over the summer, I want good quality, standard sized servos, but I'm not sure where I can get them for as cheap as possible.....

Well, some for RC, others to try out a few things with Robot Arm.
Anyways, I'll check out those websites. Thanks

How does stacking fans even do anything?
It increases the potential pressure (vacuum) differential. This could make the robot harder to lift.

Is there another website where you can buy stuff from other than VEX Robotics? I need a stronger motor and VEX Motors arent strong enough

First of all, are you thinking that sumo bots is going to be an event in New York this year? I hadn't heard so, but I'm not in New York. Anyway, there are lots of companies that sell high powered gearmotors. If I were you I'd look at a company like Robot Marketplace. They retail lots of great robot motors on their website. You can also buy them from the manufacturer, but sites like that one are a good way to search for what you want.
